Comparison of Path Selection Algorithms for ATM Networks

Abstract

The choice of routing algorithms for use in ATM networks has a large impact on network efficiency. While the PNNI specification provides a scalable framework for topology discovery and information distribution, various path selection algorithms may be used. Dynamic routing using path pre-computation is widely used, but various path selection strategies are possible. This paper the blocking rate caused by load-packing, load-balancing, shortest-hop, and hybrid strategies for path selection
