Abstract

This chapter discusses the subjects of teletraffic theory, namely, dynamic routing strategies, cellular mobile radio systems, and the application of fast packet switching techniques (used in a broadband integrated services digital network). Trunk reservation is an ideal way of preventing bistable behaviour in the network performance and for providing more efficient use of network resources. This might be achieved by using, for example, moving average estimators. Learning automata schemes have been applied to telephone routing. They continually offer calls across the available routes. Network bounds are used to obtain bounds on the performance of any dynamic routing scheme under a fixed stationary pattern of offered traffic. Dynamic Alternative routing is a simple, decentralized dynamic routing strategy consisting of between 50 and 60 main switches or nodes that are fully connected.
