Charter for Working Group
BGP is established as a protocol for provisioning and operating Layer-3
(routed) Virtual Private Networks (L3VPNs). It is also used in certain
Layer-2 Virtual Private Networks (L2VPNs).
The BGP Enabled Services (BESS) working group is responsible for
defining, specifying, and extending network services based on BGP. In
particular, the working group will work on the following services:
- BGP-enabled L2VPNs (as described in RFC 4664) that operate over IP or
MPLS packet switched network tunnels. All types of L2VPN are in scope
provided they utilize BGP for discovery, signaling, or for some other
purposes related to the VPN. But L2VPN solutions that operate over
pseudowires or use LDP and that do not utilize BGP will be addressed
by the PALS working group. Any contention in placement of the work
between these working groups will be resolved by the chairs.
- BGP-enabled VPN solutions for use in the data center networking.
This work includes consideration of VPN scaling issues and
mechanisms applicable to such environments.
- Extensions to BGP-enabled VPN solutions for the construction of
virtual topologies in support of services such as Service Function
The working group may also suggest new services to be supported by BGP
and these may be added to the working group charter subject to
The working group may work on:
- Mechanisms to support BGP-enabled services in the presence of multi-
homing of Customer Edge (CE) devices to multiple Provider Edge (PE)
devices to provide load-balancing and resilience.
- Auto-discovery of sites that participate in the BGP-enabled service.
- Data models for modeling, managing, and operating BGP-based services
using SMI or YANG.
- OAM or resiliency mechanisms operating over BGP-enabled services. But
native data plane OAM mechanisms may be worked on only in conjunction
with the working groups responsible for the relevant data planes.
- Extensions to BGP and extensions to YANG models for BGP. All such
work must be reviewed by the IDR WG, but the decision to request
publication of such work remains with the BESS WG.
The working group will also coordinate with other working groups where
appropriate. For example, with the MPLS working group for issues
related to the MPLS architecture, and the NVO3 working group for
coordination of protocols to support data center VPNs.
The BESS working group will not define new data plane or forwarding
