          Private Line Emulation over Packet Switched Networks
                      draft-schmutzer-bess-ple-02

Abstract

   This document describes a method for encapsulating high-speed bit-
   streams as virtual private wire services (VPWS) over packet switched
   networks (PSN) providing complete signal transport transparency.
