软件定义卫星网络中基于业务调度的混合路由算法
A Hybrid Routing Based on Traffic Scheduling in Double-Layer Software Defined Satellite Networks
摘要
Abstract
In order to solve the problems of high dynamic topology,large data transmission,multi-signaling cost of low-orbit satellite network,and to meet the growing demand of global coverage and massive number of mobile users,the software defined satellite network architecture and virtual topology model of high orbit and low orbit satellite collaboration are built on the basis of quality of services(QoS)of different traffic in operational performance index systems.A priority assignment function considering both traffic arrival rate and wait time is designed,and a joint inter-satellite routing algo-rithm based on traffic-aware and traffic scheduling is proposed.The algorithm includes a low-complexity intra-orbit priori-ty forwarding routing algorithm for high QoS requirement services and a link weighted routing algorithm for low QoS re-quirement services.Simulation results show that the performance of the proposed algorithm is significantly better than that of the traditional algorithm in average end-to-end delay,packet loss rate and throughput.关键词
