As the speed and number of Local Area Networks continue to increase, higher
and higher demands are placed on Wide Area Networks. To support the tremen
dous resulted traffic and prevent their links from congestion, such network
s should utilize a robust routing strategy. This paper proposes an efficien
t routing algorithm and a new model for evaluating the average packet delay
in high-speed networks. The routing strategy takes into account the level
of congestion over each link in order to choose the best possible routes fo
r each source/destination pair, whereas the proposed model is directly deri
ved from the characteristics of high-speed links. Numerical results show th
at the combination of such a strategy with the proposed model gives a good
behavior to high-speed networks and induces the generalization of the avera
ge packet delay. (C) 2000 Elsevier Science Ltd. All rights reserved.
