Abstract :
The author presents and comparatively analyzes the virtual-circuit routing control for the ISDN (integrated services digital network) frame-relay networks. The focus is on comparing the performance of the two routing control schemes: source routing and link-by-link routing. It is shown that the source routing scheme outperforms the link-by-link routing in all of the following aspects: the call setup delay and capacity, the call looping probability, and the call denial rate. It is thus recommended that the source routing control strategy with crankback mechanism be used for the ISDN frame-relay networks
