【摘要】：針對(duì)具有星間鏈路的衛(wèi)星網(wǎng)絡(luò),提出了一種軟件定義衛(wèi)星網(wǎng)絡(luò)架構(gòu)下的鏈路故障檢測和恢復(fù)方案。首先基于軟件定義衛(wèi)星網(wǎng)絡(luò)架構(gòu)設(shè)計(jì)了一種主動(dòng)上報(bào)式故障檢測機(jī)制,并設(shè)計(jì)了鏈路故障檢測算法,實(shí)現(xiàn)對(duì)衛(wèi)星網(wǎng)絡(luò)中鏈路故障的快速發(fā)現(xiàn)和準(zhǔn)確定位。在此基礎(chǔ)上,提出了一種保護(hù)加恢復(fù)式故障恢復(fù)機(jī)制來快速恢復(fù)因故障導(dǎo)致的業(yè)務(wù)中斷。最后在原型系統(tǒng)中對(duì)該方案進(jìn)行了驗(yàn)證。實(shí)驗(yàn)結(jié)果表明,該方案可以在毫秒級(jí)的時(shí)間內(nèi)快速檢測并準(zhǔn)確定位到鏈路故障,并可以在10±2ms的時(shí)間內(nèi)對(duì)故障進(jìn)行快速恢復(fù)。同時(shí),該方案可適用于多種衛(wèi)星網(wǎng)絡(luò)拓?fù)洹?br/>[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 鹵2ms. Meanwhile, the scheme can be applied to various satellite network topologies.
