1. Introduction
SCE provides early and proportional feedback to the CC (congestion
control) algorithms for transport protocols, including but not
limited to TCP. The [sce-repo] is a Linux kernel modified to support
SCE, including:
* Enhancements to Linux's Cake (Common Applications Kept Enhanced)
AQM to support SCE signaling
* Modifications to the TCP receive path to reflect SCE signals back
to the sender
* The addition of three new TCP CC algorithms that modify the
originals to add SCE support: Reno-SCE, DCTCP-SCE and Cubic-SCE
(work in progress as of this writing)

Internet-Draft sceonetwotests July 2019
In this note we run one and two-flow TCP tests across a range of
simulated path bandwidths and RTTs. One-flow tests measure SCE's
impact on TCP throughput and TCP RTT. Two-flow tests evaluate
fairness between and among several SCE and non-SCE TCP
implementations, while making several adjustments to Cake's SCE and
fair queueing parameters.
It is recognized that these tests do not simulate real-world
conditions, and will not be an indication of how SCE will perform in
all situations. However, they serve as fundamental tests for the SCE
reference implementation. Once the behavior in these tests is well
understood and theory and experiment are in agreement, additional
complexity can be added to the test procedures with the confidence
that the reference implementation's fundamentals are sound.
2. Terminology
The following terminology is used in this document:
* Path Bandwidth or Cake-limited Bandwidth: The available bandwidth
between the sender and receiver, as controlled by Cake on the
middlebox, and set by Cake's bandwidth parameter.
* Path RTT or just RTT (in context): The approximate minimum round-
trip time of packets that go from the sender to receiver and back
when the path is unloaded.
* Netem bi-directional delay: The total path RTT added by netem in
both directions.
* TCP throughput and TCP RTT: Well-known terms that apply
specifically to the flows under test.
3. Test Tools and Environment
The [Flent] tool is used for all tests. Flent uses netperf for its
TCP tests, and allows for test batches, plotting, the recording of
results and the collection of metadata in JSON format [RFC8259].
Flent both captures the measured TCP throughput from netperf, and
simultaneously uses the [ss] tool in Linux to passively monitor TCP
RTT.
All tests are performed using a three node dumbbell topology:
+--------+ +-----------+ +----------+
| Sender |--------------| Middlebox |--------------| Receiver |
+--------+ +-----------+ +----------+

Internet-Draft sceonetwotests July 2019
Figure 1: Test topology
* Sender: Runs Flent and sends data to the receiver
* Middlebox:
- Acts as a router between the sender and receiver
- Runs Cake on egress of both interfaces for queue management and
SCE signaling
- Runs netem on the ingress of both interfaces for delay
simulation, splitting the total delay in half for each
interface
* Receiver: Receives data from and reflects SCE signals back to the
sender via the ESCE (Echo Some Congestion Experienced) bit
All nodes run the SCE reference implementation kernel as of commit
56915a82 (2019-06-20), and are connected directly via Gigabit
Ethernet.
4. Tests
The tests are implemented with a Flent batch file to drive netperf
and re-configure Cake and netem on the middlebox with various
parameters. Scripts post-process the results and create csv and
markdown tables for external use, including by this document.
Unless otherwise mentioned, measurements are obtained from TCP flows
from start to finish, not at steady state. This allows for some
discussion of the differences in TCP CC algorithm behavior during
slow start and congestion avoidance. Typically, each test is run
long enough to obtain a reasonable approximation of steady state
throughput, but in a few high BDP cases slow start accounts for a
significant portion of the test length. When relevant to the
analysis of the results, this is stated in the text.
5. Results and Analysis
5.1. One-Flow Tests
The goal of the one-flow tests is to analyze the impact of SCE on the
TCP throughput and TCP RTT of single TCP flows across a range of
simulated path bandwidths and RTTs. What follows is an analysis of
the results. See Section a.1 and Section a.2 for the raw results for
TCP throughput and TCP RTT, respectively.

Table 1: Difference in TCP Throughput (reno-sce - reno),
normalized to Cake- limited Bandwidth; Columns: netem bi-
directional Delay (ms); Rows: Cake-limited Bandwidth (Mbit)
From the above TCP throughput differences we can observe:
1. Improved utilization for SCE at sufficiently high BDPs. This is
due to SCE's proportional congestion signals, which can
significantly reduce the classic Reno throughput sawtooth by
making drops or CE marks rare to non-existent. The utilization
improvement increases with BDP largely because the TCP window
recovery time after a drop or CE mark increases with BDP,
deepening the sawtooth.
2. Significant under-utilization at bandwidths <= 10Mbit, which
tends to worsen as path RTT increases. Investigation is underway
as to the source of this. These drops in utilization are however
also accompanied by drops in TCP RTT (see below).

Table 2: Difference in TCP RTT (reno-sce - reno); Columns: netem bi-
directional Delay (ms); Rows: Cake-limited Bandwidth (Mbit)
From the above TCP RTT differences we can observe:
1. Significant reductions in TCP RTT for Reno-SCE at most BDPs.
SCE's proportional congestion signals are aiding the sender in
managing queue lengths.
2. Greater reductions in TCP RTT at lower path bandwidths and RTTs.
This is because Reno-linear growth becomes relatively larger as
the path bandwidth decreases. This results in greater queue
growth in the interval before AQM activates, and a subsequently
longer drain time after congestion is signaled.
3. A slight increase in TCP RTT for SCE at high BDPs. This has been
observed to have a possible connection to the ESCE (Echo Some
Congestion Experienced) feedback strategy implemented in on the
TCP receive side. Research and optimization in this area is
ongoing.

Table 3: Difference in TCP Throughput (dctcp-sce - dctcp),
normalized to Cake- limited Bandwidth; Columns: netem bi-
directional Delay (ms); Rows: Cake-limited Bandwidth (Mbit)
From the above TCP throughput differences we can observe:
1. Improved utilization for SCE at higher BDPs. At first glance we
might assume that this is due to SCE's feedback signals improving
upon DCTCP's window recovery time, as with Reno, but another
significant part of this increase is due to DCTCP-SCE's steeper
ramp during slow start, and a test length that is short relative
to the time spent in slow start. The test is 300 seconds long,
and at a path bandwidth of 100Mbit and RTT of 160ms, DCTCP takes
a full 225 seconds to ramp up to the BDP, while DCTCP-SCE, with
its steeper ramp, takes only 80 seconds. That said, steady state
throughput at this BDP is around 87Mbit for DCTCP, and around
96Mbit for DCTCP-SCE, an increase of around 10%, so the
proportional congestion control signals also play a part in
increasing utilization.
2. Significant under-utilization at bandwidths <= 25Mbit, which
tends to worsen as path RTT increases. Investigation is underway
Heist, et al. Expires 4 January 2020 [Page 7]

as to the source of this. These drops in utilization are however
also accompanied by drops in TCP RTT (see below).

Table 4: Difference in TCP RTT (dctcp-sce - dctcp); Columns:
netem bi- directional Delay (ms); Rows: Cake-limited Bandwidth
(Mbit)
From the above TCP RTT differences we can observe:
1. A nearly across the board reduction in TCP RTT for DCTCP-SCE.
SCE's proportional congestion signals are aiding the sender in
managing queue lengths.
2. Greater reductions in TCP RTT at lower bandwidths and path RTTs.
See Section 5.1.2 for an explanation of this.
3. A slight increase in TCP RTT for DCTCP-SCE at 100Mbit / 160ms.
See Section 5.1.2 for a likely explanation of this.

5.2. Two-Flow Tests
The goal of the two-flow tests is to measure fairness between and
among SCE and non-SCE TCP flows, through either a single queue or
with fair queueing. What follows is a partial analysis of the
results, and see Section a.3 through Section a.8 for the raw results
tables.
5.2.1. Single Queue (Cake "flowblind")
Cake's flowblind parameter disables fair queueing, so that Cake uses
only a single queue. This can be used to evaluate single-queue
throughput fairness between SCE and non-SCE flows.
5.2.1.1. Reno vs Reno
It might be useful to remind ourselves that competition between two
(or more) flows of the same TCP CC algorithm is usually designed to
yield a high degree of throughput fairness in a single queue.
Looking at Jain's fairness index [RFC5166] for two flows across a
range of simulated path bandwidths and RTTs shows this to be true for
two TCP Reno flows, for example:
+-----+-------+-------+-------+-------+
| | 0 | 10 | 20 | 80 |

+-----+-------+-------+-------+-------+

5.2.1.2. Reno vs Reno-SCE
Now, we do a comparison of Reno vs Reno-SCE in a single queue, while
still using Cake's default SCE signaling ramp:

+-----+-------+-------+-------+-------+
| | 0 | 10 | 20 | 80 |
+=====+=======+=======+=======+=======+

+-----+-------+-------+-------+-------+
| 5 | 0.958 | 0.824 | 0.714 | 0.632 |
+-----+-------+-------+-------+-------+
| 10 | 0.959 | 0.719 | 0.669 | 0.698 |
+-----+-------+-------+-------+-------+
| 50 | 0.608 | 0.621 | 0.673 | 0.907 |
+-----+-------+-------+-------+-------+
| 100 | 0.560 | 0.627 | 0.668 | 0.782 |
+-----+-------+-------+-------+-------+
Table 6: reno vs reno-sce Jain's
fairness index; Columns: netem bi-
dir Delay (ms); Rows: Cake
Bandwidth (Mbit)
From the above Jain's fairness index numbers we can observe that
while there can be reasonable fairness at very low BDPs, and while
there is no starvation, fairness degrades quickly at higher
throughputs and RTTs. This is due to the Cake's default SCE
signaling ramp being tuned to provide an early signal of congestion,
to avoid CE marks and packet drops. As a result, SCE enabled flows
back off in the face of competition, whereas non-SCE flows fill the
queue until a drop or CE mark occurs.
5.2.1.3. Cubic vs DCTCP-SCE
Of particular interest to the congestion control community is
competition between the commonly used TCP Cubic algorithm and DCTCP-
SCE. It is a well-established fact that classic DCTCP will typically
out-compete Cubic in a single queue. It would be valuable if there
were a way to improve that fairness with SCE.
When comparing Cubic vs DCTCP-SCE using Cake's default SCE signaling
ramp, we can see that while there is no starvation, fairness does
degrade fairly rapidly as BDP increases:

Table 7: cubic vs dctcp-sce Jain's
fairness index; Columns: netem bi-
dir Delay (ms); Rows: Cake
Bandwidth (Mbit)
As of today, SCE by default does not lead to fairness at all BDPs
between SCE and non-SCE flows. However, efforts are ongoing to
improve this, and as we can see in Section 5.2.2, Cake's signaling
ramp can be tuned to improve this fairness.
5.2.2. Single Queue (Cake "sce-single")
As we saw in Section 5.2.1, there is room to improve SCE vs non-SCE
fairness in a single queue. One way to do this is to change the SCE
signaling ramp to reduce or delay SCE signals until closer to the
point where CE signals occur. This is the motivation behind the sce-
single and sce-thresh Cake parameters.
By default, Cake begins proportionally signaling SCE when a packet's
sojourn time in the queue is greater than half the CoDel target, and
reaches 100% SCE signaling when the sojourn time is greater than or
equal to the CoDel target. The sce-single parameter delays the start
of the ramp until the sojourn reaches the CoDel target itself, while
keeping the ramp slope the same. The sce-thresh parameter, while not
evaluated here, allows an intermediate ramp between the default and
sce-single, using values from 2-1024, with sce-thresh set to 8
yielding a ramp that's halfway in-between.
It is expected that the result of signaling SCE later is a subsequent
increase in TCP RTT, including for single flows. Thus, the
adjustment of the SCE signaling ramp is a tradeoff between the
increased utilization and reduced TCP RTT possible with SCE, and
fairness with non-SCE flows in a single queue. By using sce-single,

we can show the maximum fairness that can be achieved by tuning the
SCE signaling ramp in this way.
5.2.2.1. Reno vs Reno-SCE
Revisiting the Reno vs Reno-SCE comparison that we did in
Section 5.2.1.2, we now run the same test with Cake's sce-single
parameter set:
+-----+-------+-------+-------+-------+

Table 8: reno vs reno-sce Jain's

We can see that single queue fairness has improved considerably.
While there are results at a few bandwidth-delay combinations that
are still under investigation, single queue fairness between Reno and
Reno-SCE has largely been achieved.
5.2.2.2. Cubic vs DCTCP-SCE
Revisiting the Cubic vs DCTCP-SCE comparison that we did in
Section 5.2.1.3, we now run the same test with Cake's sce-single

Table 9: cubic vs dctcp-sce Jain's
fairness index; Columns: netem bi-
dir Delay (ms); Rows: Cake
Bandwidth (Mbit)
While it can be seen that there is an almost across the board
improvement vs Cake's default SCE ramp, there are still bandwidth-
delay combinations that do not yield a sufficient level of fairness
in a single queue. Work is ongoing to improve this.
5.2.3. Fair Queue (Cake "triple-isolate")
Cake's default triple-isolate fairness mode provides fairness among
flows and a combination of source and destination IP addresses. For
our purposes, this will effectively serve as fair queueing among
flows, as we are only using one IP on each of the source and
destination hosts.
With fair queueing, we expect to achieve a high level of throughput
fairness at most bandwidth-delay combinations.
5.2.3.1. Cubic vs DCTCP-SCE
Revisiting the Cubic vs DCTCP-SCE comparisons that we did in
Section 5.2.1.3 and Section 5.2.2.2, we now run the same test with
Cake's fair queueing enabled via triple-isolate:

Table 10: cubic vs dctcp-sce Jain's
fairness index; Columns: netem bi-

Bandwidth (Mbit)
With fair queueing, fairness is achieved for a broad range of
bandwidth-delay combinations. We do see a consistent and narrow
deviation at around 160ms between 5 and 10Mbit, which happens in
competition between SCE and non-SCE flows, regardless of the exact
algorithms in use. The cause of this will be investigated.
5.2.3.2. DCTCP vs DCTCP-SCE
As another example of SCE vs non-SCE competition with fair queueing
enabled, here we compare DCTCP vs DCTCP-SCE:

Internet-Draft sceonetwotests July 2019
As with Cubic vs DCTCP-SCE, a high degree of fairness is achieved for
most bandwidth-delay combinations, yet we do see the same small gap
in fairness at around 160ms between 5 and 10Mbit as we see with Cubic
vs DCTCP-SCE and other SCE vs non-SCE flow tests with fair queueing.
It is expected that further investigation into this will lead to a
solution.
