VPWS support in EVPN
draft-ietf-bess-evpn-vpws-12.txt
Abstract
This document describes how EVPN can be used to support Virtual
Private Wire Service (VPWS) in MPLS/IP networks. EVPN enables the
following characteristics for VPWS: single-active as well as all-
active multi-homing with flow-based load-balancing, eliminates the
need for traditional way of Pseudowire (PW) signaling, and provides
fast protection convergence upon node or link failure.
