Sender Pays

  In September 2012 ETNO, the European Telecommunications Networks
  Operators' Association, or most notably Deutsche Telekom and France
  Telecom and fellow legacy telcos in Europe published a contribution to the
  2012 World Conference in International Telecommunications (WCIT-12) with a
  proposal for regulatory reform that in ETNO's words would compel content
  providers to directly contribute to the costs on Internet communications
  infrastructure. Or, in their words, "advocating for an adequate return on
  investment based, where appropriate, on the principle of sending party
  network pays"
  (https://etno.eu/datas/itu-matters/etno-ip-interconnection.pdf).

  The proposal excited some reaction at the time, with varying levels of
  hyperbole. There was the Centre for Democracy and Technology's dire
  warning that the "ETNO proposal threatens to impair access to [an] open
  global Internet"
  (https://www.cdt.org/wp-content/uploads/pdfs/CDT_Analysis_ETNO_Proposal.
  pdf) which was pretty representative of the reaction from much of the
  Internet sector.

  At the time there were no changes arising out of WCIT-12, and the matter
  would've remained as a simmering undercurrent in the industry, were it not
  for Korea.

      Korean Content Wars

      Back in 2012 so-called "smart TVs" were the new thing, and Samsung
      launched a high-definition video streaming service in South Korea. The
      response from Korea Telecom (KT) was a rapid escalation, by blocking
      these units from accessing KT's broadband access network. Considering
      that KT was the country's major broadband access provider and Samsung
      was (and still is) a major retail brand this was always going to
      excite a public reaction. Samsung's response was to invoke the
      principles of Network Neutrality, whereby, they claimed, consumers
      should be able to use network services without any active
      discrimination by the network provider, and also casting doubt on the
      argument that the streaming service was an excessive consumer of
      network capacity in any case. The Korea Communications Commission
      stepped in and called KT's actions "inappropriate". KT backed off and
      removed the network blocks on these televisions and the inexorable
      rise of high-definition content streams continued in Korea, and all
      over the Internet, in the ensuring decade.

      But the issue never went away, and it had a reprise in 2021 when SK
      Broadband (SKB) launched a legal action, claiming that Netflix should
      pay the costs of supporting increased traffic loads in response to a
      surge of SKB's customers streaming Netflix content. The Seoul Central
      Count ruled that SKB has legitimate grounds for compensation and the
      amount is a matter of negotiation between SKB and Netflix.  Some
      Korean lawmakers have spoken out against content providers who do not
      pay for network usage despite generating large traffic volumes.
      Clouding the issue in Korea was the additional factor that some local
      content providers were already paying Korean ISPs for content stream
      access, so this dispute was easily cast as a battle between local
      enterprises and an overbearing US giant refusing to do what the local
      players are already doing.

  So, the entire set of issues of network neutrality, interconnection and
  settlements, termination monopolies, cost allocation and infrastructure
  investment economics are back with us again. This time it's not under the
  banner of "Network Neutrality," but under a more directly confronting
  title of "Sender Pays". The principle is much the same: network providers
  want to charge both their customers and the content providers to carry
  content to users.

Sender Pays

  Let's pause for a second to look at the legacy of "Sender Pays" in the
  context of this debate.

  When a service is constructed using diverse components, then the way in
  which service revenues are distributed to the various suppliers of the
  components of the service can follow a number of quite distinct models.
  There is the incremental payment model where the customer directly pays
  each service provider for their service independently of the other
  services. (Of course, imagine the privileged position of the final
  provider the customer has already invested heavily in the provision of the
  service and the final provider is in a position to charge a far higher
  price as the transaction has already accumulated a sunk cost. Then there
  are various forms of revenue redistribution models where the revenue per
  transaction is distributed by the service orchestrator to the various
  suppliers according to their inputs to support each transaction. The
  service orchestrator can bill the initiator of the service transaction or
  bill the service host. And there are various "bill and keep" models where
  a set of service providers use each other's services by essentially
  donating their service to each other. This allows each service provider to
  bill their customers for the entire service and rely on a "knock for
  knock" model where the foregone revenue for the donated services matches
  the opportunity revenue gained in the efficiencies not having to
  redistribute the fees paid by the customer for the compound service.

  If we start with the mail service, the initial models were based on
  "receiver pays" where the message accumulates a debt on its progress
  towards delivery, and the debt is paid upon delivery of the letter. The
  revenue could be redistributed to the other couriers following payment,
  but a simpler scheme is for each successive courier to purchase the letter
  from the previous courier. In this way there is a strong incentive to
  complete the delivery as the terminating courier may have already funded
  the letter's progress through the courier system.

  The Royal Mail took two revolutionary steps in the nineteenth century that
  would make it the leader in postal innovation at the time. In 1840, Roland
  Hill, an enthusiastic campaigner for postal reform, led the Royal Mail's
  introduction of the Penny Post, a cheap single rate for domestic delivery
  of letters, replacing a complex distance and letter volume tariff. This
  step made the mail service accessible to a much larger population. At the
  same time, it was intended to result in a large-scale uptake of the use of
  private correspondence, allowing the mail delivery service to realise
  economics of scale and process. The second revolutionary step was a switch
  from the recipient pays to a sender pays tariff model. This step removed a
  troubling imposition on the mail service, caused by mail refusal. Under
  the recipient-funded service model, the refusal of a mail item meant that
  the postal service incurred the cost of delivery, as well as the cost of
  return, assuming that the refused mail was ever returned. These reforms
  had a profound impact. They generated huge volumes of postal traffic,
  facilitated the development of commerce and underpinned significant
  changes in social communication. This measure coincided with the
  Industrial Revolution, when people were moving from rural areas to the
  industrial cities and from one country to another, so these postal reforms
  eased to, some extent, the social pressures that arose from this
  large-scale transformation in nineteenth century society.

  The telephone system followed this postal template. A telephone subscriber
  paid the full cost of a telephone call to the local telephone company. If
  the call involved another telephone operator to complete the call, then
  the calling operator paid the terminating provider an agreed rate for
  their part of the service. The inference from this model is that there is
  a transactional accounting model for the service, where the user is
  charged for each transaction, and it is this revenue that is used within
  the inter-provider settlement regime.

  At one point in the telephone saga one large telco acknowledged that it
  cost the company some 21c to bill their customers 25c per local phone
  call. The shift to flat fees without usage tariffs is not only attractive
  to many customers, but also attractive to many operators as a means of
  stripping out huge costs from their billing systems as well as eliminating
  one of the major points of friction with their long-suffering customer
  base.

  This also leads to the observation that a stable inter-provider settlement
  regime should be based on a uniform service tariff. How a service is
  billed to a user should determine how the service revenue is distributed
  between the various service providers who contributed to deliver the
  service. When they differ then there is an obvious opportunity for
  arbitrage and distortion.

  While the sender pays inter-provider settlement regime was used for many
  decades, that does not mean that it was free from various forms of abuse.
  A national provider could raise offshore revenue by raising the local
  international call tariffs for outbound calls, making it attractive for
  international callers to call into the provider's network. This way the
  provider could use the inter-provider payments associated with call
  termination of these calls to raise revenue.

  This opportunity was not lost on many national telcos and the resultant
  arbitrage of international call accounting settlement rates was often one
  that works to the financial disadvantage of AT&T in the US. It was no
  coincidence that when the Internet emerged AT&T lobbied US politicians and
  the administration to keep the Internet out of the clutches of the ITU-T.

  AT&T clearly believed that the root of this problem lay in the regulatory
  framework that was promoted by the ITU-T. They believed that the
  one-country-one vote system biased the entire process in favour of smaller
  nation states and the outcomes were rarely ones that coincided with AT&T's
  interests. If the Internet was to be constructed on a platform of built
  through private sector investment, then the international governance
  structures should reflect the same primacy of private sector interests.

  From the perspective of a telephone operator everyone is a customer.

Enter the Internet

  The Internet was originally conceived as a model that was, at least in
  terms of functionality, akin to the telephone network, but their
  differences are far more important that their similarities.

  There is no "call" in the Internet. There is no confirmed transaction that
  initiates a network state that has attributes of distance and duration.
  Packets are far more casual than that. Packets may be delivered to their
  intended destination, or not. They may have been solicited, or not. They
  may be intercepted by intermediaries or agents, or not. They may trigger
  other packets, or not. So, in the absence of a clearly defined transaction
  model of interaction between the Internet and its connected hosts, then a
  transactional accounting method to recover costs through transactions was
  never going to work. So, how was the Internet supposed to funded?

  Contrary to the utopian mantra of the late 80's the Internet is certainly
  not free, and ultimately there is only one source of revenue: its users
  like you and me. We each pay our local access providers some form of
  service tariff, typically in the form of a "whole of network" access
  tariff. We do not expect to be charged more if the packets are to be
  delivered to a destination on the other side of the world as compared to
  next door. We don't expect to the charged incrementally to receive
  packets, nor to send packets.  The tariffs are based on an "access" model,
  where the service provider is providing a comprehensive access model. The
  retail differentiator is typically the access bandwidth, and in certain
  markets, notably mobile services, some count of aggregate traffic volume.

  In the absence of a transactional model as a common retail structure then
  how do various providers financially balance their respective
  contributions to providing a seamless end-to-end experience to end users?
  The model used by the Internet is extremely crude, but quite effective.

  When two networks directly interconnect and exchange traffic then either
  one network is a customer of the other and pays for all traffic sent and
  received, or the two networks regard each other as "peers" in the true
  sense of the word, and exchange traffic without any payment between them.
  From an individual network's perspective, the network pays for a "transit"
  service provided by its contracted upstream providers, it receives revenue
  from its customer networks, and it "peers" with other networks where it
  exchanges access to its customer base with the peer network's customer
  base without payment, but does not provide access to its transit
  providers, nor to any other peer networks. (Figure 1).

    <https://www.potaroo.net/ispcol/2022-09/senderpays-fig1.png>
    Figure 1 – Inter-provider settlements

  Who determines who is the customer and who is the provider? Who determines
  which networks are peers of a given network? The Internet's answer is
  "nobody". The determination of roles is left to the networks themselves
  and the peering and interconnection regime functions as a market.

  The result is that all viable paths between endpoints on the Internet have
  just two parts: a part where the packet's sender is funding the packet's
  transit, either directly or indirectly via customer/provider
  inter-provider relationships, and a second part where the packet's
  receiver assumes funding responsibility for the packet's transit (Figure
  2)

    <https://www.potaroo.net/ispcol/2022-09/senderpays-fig2.png>
    Figure 2 – Inter-provider path settlements

  This Internet path property is sometimes referred to as "valley-free"
  paths. If a customer/provider relationship is an "upward" relationship, a
  provider/customer relationship is a "downward" relationship and a peer
  relationship is a "horizontal" relationship, then any viable path starts
  with a sequence of customer/provider hops (up), then at most one peer hop
  (across) then a sequence of provider/customer hops (down). All financially
  viable inter-provider paths can be presented as a "mountain" in this
  taxonomy. A "valley" would be where a packet is received by a network as a
  customer but then passed to a different transit network also as a customer
  (Figure 3). The valley segment is unfunded either by the sender nor the
  receiver.

    <https://www.potaroo.net/ispcol/2022-09/senderpays-fig3.png>
    Figure 3 – Inter-provider "valley" path

  So, we now have a lexicon of customer/provider and peer, and an associated
  understanding of the flow of money across these two relationships. What
  about paid peering?  This is a variant of a peer relationship where the
  paid peer receives the same access as a conventional peer but pays the
  provider for this access. It can be seen as a subset of a conventional
  customer relationship without access to the providers transit providers
  nor to any other peer, presumably at some discount to the normal customer
  tariff, so in many ways paid peering is just another instance of a
  customer/provider relationship, but without the stigma of being labelled
  as a customer!

Service Provision

  The internet interconnection model assumes that the interior of each of
  these networks are a collection of carriage circuits and packet switches.
  However, an ISP performs a number of other functions which can be through
  of as part of the ISP's service, and these services are bundled into the
  retail product.

  A good example of this implicit bundling can be found in the provision of
  Domain Name System (DNS) name resolver servers. These services are
  provided by the ISP and made available to the ISP's customers. They are
  typically not made available to the ISP's transit providers, nor to the
  ISP's peers. The cost of operating such services is met by the ISP's
  customer base through the ISP's tariff structure.

  Such ISP-provided services are not limited to DNS services. Prior to the
  ubiquity of Google's Gmail service many ISPs offered mail hosting, and
  perhaps web hosting and related services. In some cases, these were
  bundled into the retail tariff, and in other cases were optionally
  selected services available at an additional tariff.

  The next step in the evolution of the provider service model is the
  third-party provision of such bundled services. An ISP may pay a third
  party to provide DNS services, for example. Conventionally, this is seen
  as a service provided to the ISP, at a cost to the ISP, which is bundled
  into the ISP's retail offering.

  However, the distinction between a third party acting as an agent of the
  ISP and a third party acting independently start to get blurred when the
  service model concerns third party content hosting and similar. Having
  content delivered directly to the ISP's customer base allows for a cheaper
  and faster service for both the ISP's customers and the content provider's
  content customers. The question naturally arises that if hosting a
  third-party content service within the ISP's infrastructure saves costs
  for the content provider, then rather than the ISP paying for the service
  and folding that into the ISP's bundled tariff, shouldn't the content
  provider be paying the ISP for access services in the same vein as any
  other customer? What makes the content service a special case here that it
  gains free access to the ISP's network? Why should a content provider be
  freeloaded over the ISP network when all others pay for similar access?

  There is no objective and clear answer to this question. Instead, the
  answer is the outcome of a negotiation between the parties and the
  outcomes vary based on the relative pressure and leverage each party can
  bring to the negotiation.

Choke Points and Natural Monopolies

  A "natural monopoly" is a type of monopoly that arises where the unique
  position of the incumbent is such that there are significant barriers to
  entry for any potential competitor. A sea port might be located in a
  particularly favourable point that makes it uniquely useful for trade,
  such as the location of Rotterdam at the mouth of the Rhine, or Copenhagen
  at the point where the Baltic Sea meets the North Sea.

  There are various choke points in the Internet infrastructure which become
  natural monopolies. Exclusive use radio spectrum allocations for mobile
  service providers are a good case in point where the usable spectrum is a
  limited resource, and the spectrum auction process typically has just 3 or
  4 operators each with exclusively licensed spectrum while other intending
  mobile operators have to negotiate arrangements to share the mobile
  infrastructure. The broadband access networks also can be considered as a
  natural monopoly given the high cost of competitive deployment of multiple
  access networks. Even a single broadband deployment seeks a household
  connection rate of more than 60% of households passed to make the
  deployment cost efficient.  Multiple parallel deployments of broadband
  access infrastructure become extremely prohibitively inefficient very
  quickly.

  How does this relate to the concept of "sender pays" in relation to the
  negotiations between access providers and content networks?  To rephrase
  this in the terminology of Internet interconnections some access ISPs
  would like to position the content streamers as a "paid peer" and have
  them pay some termination fee to have their content reach the ISP's
  customers. The content streamers are asserting that they have carried
  content across oceans and across continents and have delivered the content
  to the front door of the ISP, all at their expense, and it seems like a
  crude from of extortion for the ISP to then charge the content stream to
  carry the content up to the third floor!

  It is a point of leverage for the access provider. For example, in Germany
  the three largest access providers serve some two thirds of the national
  user base, and there is no feasible way for an alternative mechanism to
  access these users, and no real prospect of churning these customers to a
  different provider. So, if the position from these three providers is one
  that demands some form of access co-payment from the content provider as a
  termination fee, then the content provider is likely to accede to these
  demands and pay the impost. To put is simply, there is no getting around a
  termination monopoly.

Negotiation or Blackmail?

  What if the content provider cannot reach an acceptable arrangement to
  directly host content servers within the access provider's network?

  This is not an abstract question. If the access ISP takes the position
  that these third-party content providers should be customers of the ISP,
  then the content provider has little choice but to either enter into a
  customer arrangement or take a step back and offer the service via an
  external peer or transit network. The content streamer then is not paying
  the access ISP a termination fee and the ISP's customers can still access
  the steamed content. Problem solved. Right?

  But that's by no means the end of the story. Part of the negotiation
  playbook as seen the access ISP deliberately allow this external peer or
  transit connection to reach the content provider to congest such that the
  service quality of the streamed content degrades significantly. This has
  happened in many contexts over the years, such as in the early 2000's when
  one large economy decided to force transit ISPs to pay a termination fee
  to access their national internet infrastructure. The forcing function was
  to only allow access only via under-provisioned access path unless the
  transit ISP was willing to pay the termination fee. The same technique is
  used today when a large access ISP deliberately pushes off-network content
  services to enter the ISP's network via an under-provisioned path which
  significantly degrades the customer experience when accessing the service.

  This deliberate differentiated treatment of traffic from certain content
  sources in order to exert leverage over them falls under the general topic
  space of "Network Neutrality." In theory the customer base has contracted
  the Access ISP to deliver all content to the customer on equal terms.
  Under network neutrality framework the network should not treat traffic
  from different sources in different ways. This has been a high-profile
  issue in the United States, where the issue of enforceable measures to
  require public Internet networks to carry all traffic in a consistent and
  neutral manner hinges on whether an Internet service is defined as an
  "Information Service" as defined by Title I of the US Telecommunications
  ACT or as a common carrier under Title II of the same act. If ISPs are
  Title II common carriers, then the FCC has the power to enforce measures
  on these providers including behaviours consistent with the principles of
  network neutrality. The 5-member Commission of the FCC changes with each
  new Presidential administration, and the attitude of the FCC has reflected
  the seesaw of US political leanings in recent years.

  Under FCC chair Tom Wheeler, the FCC voted in the 2015 Open Internet
  Order, categorizing ISPs as Title II common carriers, and making them
  subject to net neutrality principles. Under the Trump administration the
  FCC chair Ajit Pai, had the FCC reverse the 2015 Open Internet Order in
  December 2017, reverting ISPs to Title I information services.  As part of
  an executive order issued in July 2021, President Biden has called for the
  FCC under the current chair, Jessica Rosenworcel, to undo some of the
  Trump-era changes around this Title I classification.

  Negotiation Tactics vs Reality

  The conventional rationale from the access provider is that the demanded
  termination fees would allow the provider to cover the costs of
  incremental upgrades to the internal infrastructure of the access network.
  Is this really the case? Or is this a case of opportunistic rent seeking
  on the part of the access provider?

  A typical access ISP infrastructure is shown in Figure 4. The internal
  design of these networks is a collection of edge fan-outs, where each edge
  concentrator is connected inward to a Point of Presence (POP), which are
  themselves interconnected over a backbone set of trunk connections.
  Typically external connections to exchange points, transit upstream
  providers and peer networks are also made from backbone sites, so the edge
  network is dedicated for customer connections.
 
    <https://www.potaroo.net/ispcol/2022-09/senderpays-fig4.png>
    Figure 4 – Generic Access ISP design

  Over the past decade streaming has taken over much of the traffic profile
  for a retail ISP. All CDNs offer settlement free peering and provide
  private interconnects over IXs irrespective of the size of the ISP (Figure
  5a). Larger ISPs may be offered central cache servers or server clusters
  without cost to the ISP (Figure 5b). Large ISP may use CDN cache clusters,
  or use caches deployed closer to the edge of the internal infrastructure
  (Figure 5c). In this edge deployment scenario, it's unclear as to the real
  extent of the impact of this streaming content in the ISP's internal
  infrastructure, as the content streams are passed on demand only across
  the access tails rather than across the entire ISP's internal
  infrastructure.

    <https://www.potaroo.net/ispcol/2022-09/senderpays-fig5c.png>
    Figure 5c – Edge Content Streaming

  What is also unclear is the extent to which existing customer payments
  have 'covered' the ISP's costs. Given that the major case to deploy a
  high-speed broadband network is to stream content, then it does seem to be
  either negligent of the access ISP sector if they failed to factor in this
  use pattern while at the same time deploying ever faster 5G mobile
  services and high-speed fibre broadband infrastructure. Or, more likely,
  this use case scenario was already factored into the access product from
  the outset and the claims that the streaming use by customers have created
  an unanticipated load on their network infrastructure to be specious at
  best, or, more likely, an outright lie.

  The critical factor for residential broadband deployment is not the costs
  to pass a house (in USD that cost still appears to be some $1,000 per
  household as part of a larger deployment), but the take up rate of the
  service. The cost of the tie line to the house is some $800. If the take
  up rate is 50% then cost of the project rises by 55% as compared to a 100%
  take up rate. The costs associated with the take up rate of broadband
  dominate the economics of broadband deployment, and the marginal cost of
  bandwidth and volume are relatively minor cost factors. Accordingly, it's
  challenging to substantiate the claims of significant costs on the part of
  the Access ISP to meeting the traffic demands of carrying streaming
  services. 

Consequences

  The issue here is that in a relatively unconstrained negotiation the
  outcomes tend to favour the larger player. If the content provider is a
  major player with content that customers are demanding, then the ISP is
  under some pressure to reach an acceptable outcome or risk customer churn
  to a rival access provider. On the other hand, a major access provider is
  able to present an effective termination monopoly to the content provider
  and can demand a termination fee from the content provider as there are
  few alternatives to the content provider other than withdrawing from that
  market completely while the content streaming business is subject to a
  wave of competitive pressure from the various new entrants.

  What improves the negotiating position for both parties is relative size.
  The greater the customer share the greater the leverage the access ISP can
  bring to the negotiation. The same applies to the content provider, and
  the larger the content provider in terms of market share the better its
  ability to capture a significant committed customer base, and then use
  this committed customer base as leverage in the negotiation with the
  access ISP.

  The common outcome for both parties is increased pressure to aggregate and
  increase their size, or, in other words, continue along the inexorable
  path to centralization and large-scale industry consolidation, which is
  already a prominent issue for today's digital world.

Options for the Regulator

  How should a regulator respond to this situation?

  It's clear that a detailed regulatory response that sets forth strict
  guidelines on how termination fees can be levied, and under what
  circumstances, stands a strong risk being overtaken by events in
  relatively short order. Overly prescriptive directions have the risk of
  rapid obsolescence as the players, the services, and the technology
  options change.

  The larger danger lies in potentially compromising the ability of the
  national economy to sustain continued private sector investment in
  broadband infrastructure through increased regulatory risk. There are very
  few economies where the construction of a broadband access infrastructure
  has been undertaken as a public sector activity, and if it's a private
  sector activity then each national environment is competing for investment
  funds with other national environments as well as other activity sectors.
  The capital returns on infrastructure investment in this sector have been
  generally rather poor, and this is reflected in the protracted exercises
  that make up various national broadband rollout programs.

  However, sustaining a favourable environment for private sector investment
  in infrastructure is not the only objective here. An overly predatory
  private sector that exploits a monopoly position to the detriment of
  local; consumers and local enterprises is equally a major liability for
  any economy. In this post-industrial social landscape, many economies are
  pinning their hopes for a sustainable future on a vibrant and healthy
  digital economy. A fundamental fracture in the relationship between
  content and carriage services imperils any such aspirations for a healthy
  and efficient digital economy at a national level.

  The currently fashionable regulatory position is seen in the response in
  Korea: "the parties must negotiate in good faith. We will not dictate the
  outcomes of such negotiations, but we will insist that it is undertaken in
  a genuine spirit of reaching some mutually tenable common position as an
  outcome." But what is a "good faith" negotiation if one of the parties
  maintains that the outcome is unfair? If such negotiations take the form
  of a set of bilateral negotiations, then presumably a large access ISP
  with a significant customer population can leverage a more advantageous
  outcome than a smaller ISP. Does this provide yet more barriers to entry
  for smaller ISPs with the consequent erosion of a diverse competitive
  access ISP environment. Do similar considerations apply in the content
  service space? Are larger content providers able to force outcomes that
  are more advantageous to them, as compared to smaller content providers?
  Again, does this provide unwelcome incentives for more aggregation in the
  content service sector?

  In any case, the pressure for some further response appears to be very
  high in Europe. In a recent media report
  (https://totaltele.com/european-commission-to-ask-telcos-for-proof-that-us
  -tech-giants-should-pay-for-traffic/) it was noted that there is some
  enthusiasm for the European Commission to move ahead with such a structure
  of negotiated termination fees, while other commentators are concerned
  that there are some serious longer term concerns with the erosion of
  network neutrality and the potential for network capture as a consequence.

Be careful what you wish for

  What happens when the content platforms consolidate further such that the
  few enterprises remaining in the field are truly massive, far larger then
  even today?

  What happens when these content behemoths have sufficient capital
  resources to play a dominant role in the access provider by virtue of
  being their largest and most significant customer through such termination
  fees? For any enterprise if a small subset of customers dominates the
  revenue profile for the enterprise, then the enterprise will naturally
  focus on the needs of these customers at the expense of all others.
  Ultimately, such a skewed situation could reach the point where the
  dominant customers effectively take over the enterprise.

  This is not idle speculation in this industry. The last decade has seen a
  comprehensive change in the submarine cable landscape and these days the
  majority of new cable projects and most of the portfolio of
  intercontinental cable connectivity is undertaken only by the very largest
  of today's content providers. More than 80% of the current trans-Atlantic
  cable capacity is controlled by content providers, not by the traditional
  carriage industry. So dominant is the content sector's position in this
  domain that their control of the submarine cable sector is in itself a de
  facto monopoly. No single carriage entity can amass the volume of content
  to justify the construction of new terabit cable project, nor have carrier
  consortia been up to the task, and few, if any, of the carriage providers
  have access to investment funds to pay for such a project. The outcome has
  been that content industry is no longer a customer in this sector. It is
  also its own provider for this form of carriage.

  What then of the last mile access market? Can it sustain itself as an
  independent sector? Are there sufficient uses and sufficient competitive
  interest in the access market to withstand the pressure that could be
  placed upon it from a largely aggregated and highly lucrative content
  sector? For example, Google has been an interested low-level player in the
  US access markets for many years. Google's Fi service and Google Fibre
  appears to be deliberately positioned as low level "foot-in-the-water"
  exercises that are exploring the space. What might happen if their level
  of interest in the access sector were to dramatically increase? Consumers
  would probably be all in favour of such a move, particularly if it
  involved a dramatic increase in service quality, reliability, and a
  massive drop in cost to the consumer. What would be the regulatory
  justification to resist such a move, assuming that it was confidently
  expected that it would result in a vastly cheaper and more capable digital
  infrastructure? We have already seen the shift to content-based
  aggregation for much of or digital service environment, from mail and
  messaging to document management and commerce, based on offerings that
  have slashed prices to consumers and increased to robustness and quality
  of the offered service. The regulatory response to such fundamental
  changes in this landscape has been a general silence. If the current
  efforts to force the content sector to engage with the access network
  operators are indeed successful, and so successful that the content sector
  takes a substantial position in not just subsidising but directing
  broadband access infrastructure activities, then what would be left in the
  access sector? Would they still remain as a separate sector? Or would the
  broadband access sector become part of an even larger entrenched monopoly
  of the current suite of content providers?

  With particular reference to the European Community, there is already a
  visible level of concern with the level of offshore control of the
  regional DNS infrastructure, as evidenced by the DNS4EU program. It
  appears to me that the concerns over foreign control of critical
  infrastructure applies as a far greater strategic concern if the subject
  of the foreign control was the entire national broadband access
  infrastructure. In that context, inviting these offshore entities to
  undertake what could become a major investment in this strategically
  important local asset strikes me as a triumph of short-term opportunism by
  a small clique of actors at the expense of a broader common strategic
  interest for the European region, and others of course.

  There is also the concern as to whether this could ever be undone if we
  later regret it. The last time we saw large scale social upheaval was as
  an outcome of the industrial age at the end of the nineteenth century.
  Once the industrial behemoths of the day had consumed their competition
  and become de facto monopolies, they turned their attention from the
  present to the future and worked diligently to create a dominant position
  that would echo through the ensuing decades. General Electric,
  Westinghouse, JP Morgan, Standard Oil are still with us from this period.
  I have no doubt the current digital behemoths have similar aspirations of
  an enduring legacy, and once they convert such termination payments into
  structural subsidisation of access networks, then they can thereby exert
  greater levels of controlling interest in this critical infrastructure
  component.

  The old adage applies here of being very careful of what you wish for! We
  really may not have the tools or even the understanding of how to cope
  with the outcomes were this comprehensive hegemony of content over
  carriage to eventuate.
