Pseudo Wire Emulation Edge to Edge (PWE3) is a layer 2 Virtual Private Network (VPN) protocol that provides tunnels to emulate services (such as Frame Relay (FR), ATM, Ethernet, TDM SONET/SDH) over packet switched networks (IP, MPLS). This protocol connects traditional networks and Packet Switched Networks (PSNs) to share resources and extend networks. It is the extended Martini protocol. It extends new signaling (optimized signaling overhead) and specifies the negotiation mechanisms for MH-WP to enrich the networking modes. This paper describes the working principle, critical technologies, advantages and defects of the PWE3 technology. It also provides suggestion to PWE3 application and deployment.
