摘要
为实现网络流量均衡和网络性能优化,借鉴多路径路由算法分流传输的思想,在单路径快照聚合路由(SIR)算法基础上提出了多路径快照聚合路由(SIMR)算法.针对基于卫星网络的空间信息快速回传的场景,分析星座的可见性,在机会网络仿真环境ONE中进行仿真实验,对比延迟可容忍卫星网络路由算法(CGR)、基于多协议标签技术(MPLS)的SWP算法和SIR算法,统计分析成功交付率、节点存储占用率、链路利用率等6项指标.结果表明:SIMR算法能更有效地实现流量均衡,从而实现信息快速回传.
For optimization of network traffic balance and network performance, with the idea of split-flows, snapshot integration multipath routing(SIMR) is proposed based on the snapshot integration routing(SIR) for single path. In the paper, for the information fast returned satellite network, the visibility of constellation is analyzed and simulated in ONE. SIMR is compared with contact graph routing(CGR) for delay-tolerant satellite network routing, shortest widest path(SWP) based on multi-protocol label switching(MPLS) and SIR. Then successful delivery rate, node storage occupancy, link utilization and other six indicators are analyzed. The results reveal that SIMR algorithm can achieve traffic balance more efficiently, and it achieves information fast return of satellite network.
