【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]:For satellite networks with intersatellite links, a link fault detection and recovery scheme based on software defined satellite network architecture is proposed. Firstly, an active reporting fault detection mechanism is designed based on the software defined satellite network architecture. A link fault detection algorithm is designed to realize fast detection and accurate location of link fault in satellite network. A protection and recovery fault recovery mechanism is proposed to quickly recover the service interruption caused by the fault. Finally, the scheme is verified in the prototype system. The experimental results show that, The proposed scheme can quickly detect and locate link faults in milliseconds, and can quickly recover faults in 10 卤2ms. Meanwhile, the scheme can be applied to various satellite network topologies.
