Abstract

The main aspect covered by signaling systems and protocols for ATM networks concerns the possibility to manage, maintain, and control a user-driven communication between arbitrary ATM end-systems connected to an ATM network. The tasks and procedures defined for, e.g., setting-up an ATM connection, are often very different concerning the rrelevant specifications of various working bodies (such as ITU-T or ATM-Forum) or certain vendors, although the basis to be done for maintaining ATM connections are always principally the same. The reason for this situation is, that the intentions of working bodies are different and each one of them follows specific strategies for certain scenarios (such as for point-to-point unicast or point-to-multipoint multicast). Nevertheless, various types of characteristics (such as addressing, multicast, or interworking) are requested from applications residing on top of ATM networks.Therefore, this survey of signaling systems and protocols for ATM networks identifies for several of selected approaches (such as Q.2931, UNI 3.1, or CMAP) important characteristics and relevant scenarios. Furthermore, a table-based comparison of some approaches has been added
