| Abstract | Dynamic routing is a simple way to improve network performance without additional investment. Many routing techniques are developed by different operators to support their own exchange. The multi-vendor exchanges are represented in this study by nodes having different sizes, trunk capacities, offered traffics and routing schemes. The performance of network that contains multi-vendor exchanges has been studied here when network is using different routing schemes. The study is based on simulation of non-homogenous network, with three offered traffic cases. First when network has balanced offered traffic at different load (balanced load condition), when the significant node in network has sudden raise of offered traffic (unbalance load condition) and when links between nodes are interrupted (link failure condition). Results are presented from call blocking, link efficiency and revenue viewpoints; e.g. if some nodes in network are using different routing scheme, the effect of that scheme to overall performance of network is studied. The performance of interworking between different routing schemes has been studied in two case as 1) when all nodes except one use DAR scheme while only one identical node is using STR scheme, 2) all but two nodes use DAR scheme while two identical nodes are using STR scheme. In these cases both the overall network performance and the individual node performances are better than when using only DAR method in all the nodes. Simulation results show that at moderate offered traffic, although providing STR scheme only in some nodes in the network, the overall network performance is improved. But at high traffic load, the direct routing method gives higher performance in any traffic pattern. |
