摘要

With regard to the limited link time of the inter-satellite links in LEO satellite constellation network, this paper proposes a routing algorithm which takes the limited link time into account, and supports traffic engineering. The routing algorithm is based on MPLS satellite network. The initial weight of links is defined to be function of residual bandwidth and link time. And during the weight adjustment period, link weight is dynamically changed by its critical degree. The algorithm can improve short communication time and limited total network traffic that caused by the link handover. Simulation results show that the algorithm has a good performance in terms of request rejection rate, average traffic per node and total network traffic.
