【摘要】：針對具有星間鏈路的衛(wèi)星網(wǎng)絡,提出了一種軟件定義衛(wèi)星網(wǎng)絡架構下的鏈路故障檢測和恢復方案。首先基于軟件定義衛(wèi)星網(wǎng)絡架構設計了一種主動上報式故障檢測機制,并設計了鏈路故障檢測算法,實現(xiàn)對衛(wèi)星網(wǎng)絡中鏈路故障的快速發(fā)現(xiàn)和準確定位。在此基礎上,提出了一種保護加恢復式故障恢復機制來快速恢復因故障導致的業(yè)務中斷。最后在原型系統(tǒng)中對該方案進行了驗證。實驗結果表明,該方案可以在毫秒級的時間內快速檢測并準確定位到鏈路故障,并可以在10±2ms的時間內對故障進行快速恢復。同時,該方案可適用于多種衛(wèi)星網(wǎng)絡拓撲。
[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.
