Compared with traditional cluster, the cooperative - type - cluster has carried the sync net packets from all real server ’ s network cards to director and set up a priority queue of sync net packets for dmcs, then it has transmitted them through the cooperation of nodal servers and directoer, it has made that the nodeal server lost efficiency suddenly or automatically joined or broke away from the cluster not influence the whole system ’ s normal running again ; meanwhile, it can avoid reducing handling capacity even appearing phenomenon of “ living locking ” in high load
與傳統集群相比，合作式集群從各真實服務器端網卡報文隊列中分離出請求報文移至負載均衡器端，建立針對分散式測控系統的請求任務報文優先權排隊隊列，通過節點服務器與負載均衡器合作進行報文轉發，使得節點服務器突然失效或自動加入脫離集群不再影響整個系統的正常運行;同時，也能避免在高負載下處理能力降低甚至出現「活鎖」的現象。 -
