A high priority real-time connection is denied admission to an ATM network if sufficient bandwidth is not available along all suitable paths through the network. Bandwidth reallocation and dynamic active channel re-routing are techniques that can be used to admit high priority real-time connections where traditional CAC techniques would deny admission. A node can select lower priority channels, reallocate their bandwidth to the new higher priority connection being admitted, and reroute those channels so that their QoS requirements and transmission deadlines can still be satisfied. At call admission time, one or more backup channels are established for those primary channels that are likely to be selected as victims for bandwidth reallocation. This allows reroutes to be handled quickly and efficiently. When reroutes occur, the protocols ensure that the transmitted data are received on time and in sequence, which is essential for real-time communications. SANRoP, a cell based discrete event simulator, was developed to simulate these protocols in an ATM network in order to determine how well they perform.
