Adaptive map configuration and dynamic routing to optimize the performance of a satellite communication network

Availability of alternate routes are shown to enhance the performance of non-hierarchical circuit switched networks at moderate load conditions on which the networks typically operate. But alternate routes introduce instability at heavy and overloaded conditions and at these load conditions the network performance is found to deteriorate. To alleviate this problem, one of the control mechanism used is to reserve a fraction of the capacity of each link for direct routed calls. In this work, the feasibility of changing the facilities of a satellite network is taken advantage in optimizing the performance of such a network. A mesh connected, circuit switched satellite communication network is optimized by reconfiguring the network with proper allocation of link capacities and placing an optimal reservation scheme. The network load is measured and the network is continually adapted by reconfiguring the map to suit the current traffic conditions. The routing is performed dynamically. The results from the simulation study shows this method of traffic management performs better than the pure dynamic routing with fixed configuration
