DIDA: a Distributed, Dynamic and Adaptive VP bandwidth management scheme for ATM networks

Virtual Path (VP) provisioning has gained wide acceptance as an effective r esource management technique for improving transmission efficiency in ATM n etworks. VP bandwidth management in particular could absorb short-term fluc tuations in traffic and improve call-blocking probability. In this paper, w e propose a distributed and dynamic VP bandwidth management scheme called D IDA, which absorbs medium scale traffic fluctuations and improves the call blocking probability. The proposed scheme incorporates an adaptive traffic estimator that is suitable even for VPs carrying heterogeneous traffic. Sim ulation studies conducted on DIDA show that the adaptive estimator of DIDA improves the call blocking probability in an ATM network, with VPs carrying heterogeneous traffic while maintaining fairness among different call type s at the same time.
