【摘要】：針對(duì)現(xiàn)有旅級(jí)指揮信息系統(tǒng)中存在服務(wù)器單點(diǎn)失效問(wèn)題,設(shè)計(jì)并實(shí)現(xiàn)了基于路徑與網(wǎng)絡(luò)質(zhì)量相結(jié)合的服務(wù)動(dòng)態(tài)遷移機(jī)制.該機(jī)制基于分布式指揮系統(tǒng),是服務(wù)器集群技術(shù)的應(yīng)用.該算法有以下特點(diǎn):可以針對(duì)不同請(qǐng)求分析網(wǎng)絡(luò)質(zhì)量,確定網(wǎng)絡(luò)資源,制定動(dòng)態(tài)閥值,形成節(jié)點(diǎn)候選方案;引入時(shí)間距離,并與負(fù)載組合,選擇最佳遷移路徑;取消前端服務(wù)器,實(shí)現(xiàn)系統(tǒng)容錯(cuò),同時(shí)實(shí)現(xiàn)服務(wù)動(dòng)態(tài)遷移.經(jīng)實(shí)驗(yàn)證明,該算法與輪循算法相比,性能提高49.65%,一定程度上節(jié)約了時(shí)間成本.該算法已應(yīng)用到旅級(jí)指揮信息系統(tǒng)中.
[Abstract]:Aiming at the single point failure of server in the existing brigade command information system, a dynamic service migration mechanism based on the combination of path and network quality is designed and implemented, which is based on distributed command system. This algorithm has the following characteristics: it can analyze network quality according to different requests, determine network resources, make dynamic threshold, form node candidate scheme, introduce time distance, and combine with load. Choosing the best migration path, canceling the front-end server, realizing system fault tolerance, and realizing the dynamic migration of service. The experimental results show that the algorithm is compared with the rotation algorithm. The performance is improved by 49.65, and the time cost is saved to some extent. The algorithm has been applied to brigade level command information system.
