INTERNET-DRAFT Sami Boutros Intended Status: Standard Track VMware Ali Sajassi Samer Salam Cisco Systems John Drake Juniper Networks J. Rabadan Nokia Expires: October 16, 2017 April 14, 2017 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.
