Abstract

   This document describes the General Switch Management Protocol
   Version 3 (GSMPv3).  The GSMPv3 is an asymmetric protocol that allows
   one or more external switch controllers to establish and maintain the
   state of a label switch such as, an ATM, frame relay or MPLS switch.
   The GSMPv3 allows control of both unicast and multicast switch
   connection state as well as control of switch system resources and
   QoS features.

Acknowledgement

   of GSMP is based on their work.
