2. Introduction
This document defines a Policy Information Base (PIB) for
partitioning a single switch into a set of virtual switches.
([SPPI] describes a structure for specifying policy information
that can then be transmitted to a network device for the purpose
of configuring policy at that device. The model underlying this
structure is one of well defined policy rule classes and instances
of these classes residing in a virtual information store called
the Policy Information Base (PIB).) The partitioning PIB defined
here is largely based on the Base Switch Partitioning MIB (MSF
00.069) [MSF-VSMIB]. However, unlike that MIB, this document does
not provide a management interface for the switch as a whole but
instead only specifies the ports and resources assigned to virtual
switches. The management interface(s) to discover switch
resources as a whole are outside the scope of this document.
3. Partitioning Function
There are four logical interfaces for managing a switch that can
be divided up into multiple virtual switches. They are (1) the
interface to control the behavior of the switch as a whole, (2)
the interface to control the behavior of each virtual switch, (3)
the interface to query what resources exist on the switch, and (4)
the interface to create and delete virtual switches and to
partition the available resources amongst these virtual switches.
Interfaces 1 and 2 are likely to be very similar and PIBs
currently exist for the purpose of managing these non-virtualized
parts of switches. These interfaces are not considered further in
this document. While the latter two interfaces are clearly
related, they perform different functions - discovery and
configuration respectively. The motivation for separating these
functions into different PIBs is that in many cases other PIBs
already support resource discovery. The missing element is a PIB
to support the virtual switch partitioning function. Therefore,
in this document, PIBs for discovering switch resources are
assumed to exist and we instead focus on the PIB for the virtual
switch partitioning function. This partitioning function creates
and deletes virtual switches on a switch and assigns resources in
the support of those virtual switches.
4. Base Switch Resources
Anderson et al. Expires January 2001 [Page 2]
Internet Draft IP Forwarding PIB July 2000
The following switch resources may be partitioned amongst virtual
switches.
4.1. Bandwidth, Buffer Space, and Queue Schedulers
The bandwidth, buffer space, and queue schedulers assigned to a VS
can be abstracted using a single parameter: the equivalent
bandwidth per port assigned to the VS in both the incoming and
outgoing directions. The equivalent bandwidth is associated with
a performance target. The performance target is most common in
the form of a loss target but also a delay target can be used.
4.2. Label Space
Label space resources are allocated independently for the incoming
and outgoing directions of switch ports. Label space must be
specified as a set of potentially non-contiguous ranges to allow
for the flexible allocation of label space in a dynamic
environment. Depending on what service a port provides the label
space can be of a different form, e.g., the label space is VPI/VCI
for an ATM port and DLCI for a frame relay port.
4.3. Routing Table Space
The abstraction for routing table space is more complex than that
for label space because different switches implement routing
tables of different granularities. Some switches implement a
routing table at each port, while others implement a common
routing table, which is shared by the connections that go through
all of the ports.
4.4. Control Link Bandwidth and Processor Cycles
When multiple VSs exercise control over separate LSPs, which are
hosted on the same physical switch, they potentially share the
processor on which the Switch Partitioning Functionality and
Switch Control Functionality is executed. Multiple controllers may
also share a communication link to the switch.

6. Security Considerations
The information contained in a PIB when transported by the COPS
protocol [COPS-PR] may be sensitive, and its function of
provisioning a PEP requires that only authorized communication
take place. The use of IPSEC between PDP and PEP, as described in
[COPS], provides the necessary protection against these threats.
7. Intellectual Property Considerations
The IETF is being notified of intellectual property rights claimed
in regard to some or all of the specification contained in this
