A Call Model For Multipoint Communication in Switched Networks

Abstract

We describe a call model for multipoint communication in switched networks. The model provides network clients with dynamic multipoint, multiconnection communication channels, which we term calls. Clients create, manage and manipulate calls using our Connection Management Access Protocol (CMAP). The call model provides basic interconnection services suitable for local and wide area networks, where more sophisticated services can be layered over this substrate.

Cell pipes are implemented in the ATM network by setting up low level connections between each switch traversed by the cell pipe. When a cell arrives at a switch, its VPI/VCI is examined and used to route the cell to the appropriate output link. The VPI/VCI is then updated so as to be meaningful to the next switch on its ro..
