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.
