Abstract

This document describes base requirements for the Pseudo-Wire Emulation Edge to Edge Working Group (PWE3 WG). It provides guidelines for other working group documents that will define mechanisms for providing pseudo-wire emulation of Ethernet, ATM, and Frame Relay. Requirements for pseudo-wire emulation of TDM (i.e., "synchronous bit streams at rates defined by ITU G.702") are defined in another document. It should be noted that the PWE3 WG standardizes mechanisms that can be used to provide PWE3 services, but not the services themselves.

Abstract

   This document describes base requirements for the Pseudo-Wire

   Emulation Edge to Edge Working Group (PWE3 WG).  It provides

   guidelines for other working group documents that will define

   mechanisms for providing pseudo-wire emulation of Ethernet, ATM, and

   Frame Relay.  Requirements for pseudo-wire emulation of TDM (i.e.,

   "synchronous bit streams at rates defined by ITU G.702") are defined

   in another document.  It should be noted that the PWE3 WG

   standardizes mechanisms that can be used to provide PWE3 services,

   but not the services themselves.
