Abstract:
IEEE 802.1 Provider Backbone Bridges (PBB) [IEEE.802.1Q-2011] defines
an architecture and bridge protocols for interconnection of multiple
Provider Bridge Networks (PBNs). PBB was defined in IEEE as a
connectionless technology based on multipoint VLAN tunnels. PBB can
be used to attain better scalability in terms of number of customer
MAC addresses and number of service instances that can be supported.
Virtual Private LAN Service (VPLS) [RFC4664] provides a framework for
extending Ethernet LAN services, using MPLS tunneling capabilities,
through a routed MPLS backbone without running RSTP or MSTP across
the backbone. As a result, VPLS has been deployed on a large scale in
service provider networks.
This draft discusses extensions to the VPLS Provider Edge (PE) model
required to incorporate desirable PBB components while maintaining
the Service Provider fit of the initial model.
