This paper describes the current state of network signaling for ATM broadband SVC call control, and the direction of evolution of the current work in the ITU, ANSI and the ATM Forum activities. The most recent issues of the signaling protocols will support enhancements to the basic call control such as point-to-multipoint network connections, variable bit rate, look-ahead, and negotiation/modification of connections. Future activities are aimed at the areas of extensions to basic connection control, adaptation of narrowband procedures such as echo control and mobility, and linking of ATM signaling with higher level application control efforts such as DSM CC and TINA. These extensions to the signaling protocol will allow signaling to support basic connection services with a variety of different connection types. More complex multimedia services are likely to be provided using service-specific control protocols, where basic signaling provides a component part for the control of network connections.
