This text has analysed load balancing method of existent especially lvs cluster system and recommended the net packet and netfilter ’ s frame structures in the linux operating system ; it has compared the cooperative - type - cluster with tradictional cluster in the net packets ’ queue ways and with active cluster in the load balancing dispatcher way, which has reflected the superiority of cooperation type cluster ; the three major parts of the cooperative - type - cluster have been designed and realized in this text, which includes sync packets ’ priority service for dmcs 、 “ priority and avoid sudden load unbalance ” dispatch way at the cooperation of nodal servers and director and active nodal server which ensure cluster normally running when cluster join or rduce node server ; the cooperative - type - cluster ’ s control frame controlled by homepage has been constructed ; the mulit - services cluster system has been realized ; this text has used the existing server pressure testing tools to test the cooperative - type - cluster and lvs cluster, then has comparaed and analysed the two
本文分析了現有服務器集群特別是lvs集群系統的負載均衡方法，介紹了linux系統下的報文和netfilter的框架結構;將所提出的合作式集群與傳統集群在報文排隊方式上進行比較，與主動式集群在負載均衡調度方式上進行比較，體現了合作式集群的優越性;設計並實現了合作式集群體系結構的三大部分:針對分散式測控系統的加權服務、負載均衡器與節點服務器合作式「加權防突」負載調度、保證集群運行不受加減節點干擾的主動性真實服務器;構建了通過網頁界面控制合作式集群的控制框架;實現了一個可運行的合作式多服務集群系統，運用現有服務器壓力測試工具對合作式集群和lvs集群進行負載測試，並對測試結果進行比較分析，同時通過壓力測試實現加權服務。
