    abstract =  {This document describes how E-VPN can be used to support virtual private wire service (VPWS) in MPLS/IP networks. E-VPN enables the following characteristics for VPWS: 1) active/standby redundancy, 2) active/active multi-homing with flow-based load-balancing, 3) eliminates the need for single-segment and multi-segment PW signaling, and 4) provides faster convergence using data-plane prefix independent convergence upon node or link failure in comparison to control-plane convergence with PW redundancy.},
