摘要/Abstract

摘要： 针对具有星间链路的卫星网络,提出了一种软件定义卫星网络架构下的链路故障检测和恢复方案。首先基于软件定义卫星网络架构设计了一种主动上报式故障检测机制,并设计了链路故障检测算法,实现对卫星网络中链路故障的快速发现和准确定位。在此基础上,提出了一种保护加恢复式故障恢复机制来快速恢复因故障导致的业务中断。最后在原型系统中对该方案进行了验证。实验结果表明,该方案可以在毫秒级的时间内快速检测并准确定位到链路故障,并可以在10±2ms的时间内对故障进行快速恢复。同时,该方案可适用于多种卫星网络拓扑。

Abstract: Link failure detection is an open issue remained to be solved in satellite network with inter-satellite links.This paper proposed a novel strategy of link failure detection and network service recovery based on software-defined satellite network(SDSN) architecture.In this architecture,the link failure detection mechanism is designed to detect and locate link failures in satellite network,while the failure recovery mechanism combines both protection and restoration to migrate and recover the interrupted services.To prove the efficiency of the proposed strategy,we conducted an experi-ment on a prototype system.The results show that the link failures can be fast located,and the recovery durations are kept in 10±2 milliseconds.The architecture and corresponding strategy can be adapted to any other satellite network topology.
