Connection Management Network Protocol (CMNP) Specification
John DeHart, Dakang Wu · 1999
This document specifies a Connection Management Network Protocol (CMNP) for managing multipoint multimedia communications in high-speed packet switched networks. We target CMNP to networks employing the Asynchronous Transfer Mode (ATM) communication standard. We define a multipoint connection as a communication channel between two or more clients of the network, where all data sent by one client is received by all other clients who have elected to receive. A point-to-point connection is a special case of a multipoint connection involving only two clients. CMNP specifies message formats used to pass the control information among network nodes to create, modify and delete multipoint connections. CMNP also defines the actions at network nodes when a message is received. Once a connection is established, network nodes exchange data using protocols other than CMNP. 1.
