A METHOD FOR ADMISSION CONTROL AND ROUTING BY ALLOCATING NETWORK RESOURCES IN NETWORK NODES

摘要

A method regulates the admission control of, and requests for routing of, vi rtual circuits in a network by determining network resource requirements for the v irtual circuits. In particular, the network resource requirements are based on a s et of parameters used to control the flow of information from a communications dev ice onto the virtual cirucit. The requirements for network resources typically include buffer space requirements in network nodes and bandwidth requirements in net worklinks, and the parameter used to control the flow of information are those associated with an access regulator. The network resource determination is made for th e case where lossless performance in the network is required and in the case where statistical multiplexing with limited loss is allowed. Both constant bit rat e and variable bit rate information is considered.
