Requirements and Framework for Point-to-Multipoint Pseudowires
over MPLS Packet Switched Networks
Abstract
This document presents a set of requirements and a framework for
providing a point-to-multipoint pseudowire (PW) over MPLS Packet
Switched Networks. The requirements identified in this document are
related to architecture, signaling, and maintenance aspects of point-
to-multipoint PW operation. They are proposed as guidelines for the
standardization of such mechanisms. Among other potential
applications, point-to-multipoint PWs can be used to optimize the
support of multicast Layer 2 services (Virtual Private LAN Service
and Virtual Private Multicast Service).
