摘　　要：在分布式共享内存(DSM)中使用多播进行节点间的消息传输,可以大幅节省通信开销,但传统多播具有不可控性。为此,提出一种将基于软件定义网络(SDN)实现的多播应用于DSM中的方案。设计一种基于多播的DSM系统,并以基于SDN实现的多播为其提供数据传输。实验结果表明,与传统以太网相比,该方法能够有效降低DSM中的数据传输延迟,为DSM系统提供良好的通信性能保障。In Distributed Shared Memory（DSM）,using multicast to transmit messages between nodes can greatly save communication costs,but traditional multicast is uncontrollable. To solve this problem,a scheme to apply multicast based on Software Defined Network（ SDN） to DSM is proposed. A DSM system based on multicast is designed,and data transmission is provided for it with SDN based multicast. Experimental results show that,compared with traditional Ethernet,this method can effectively reduce the data transmission delay in DSM and provide good communication performance guarantee for DSM system.
