摘要: 对选播服务的网络负载均衡做了研究,提出一种支持多协议标签交换(MPLS)流量工程的选播路由算法(ART).ART基于最小冲突路由机制,通过MPLS约束路由的标记分发协议(CRLDP)建立1条从选播服务器到客户方向的标记交换路径(LSP),并预留带宽资源.仿真结果表明,ART能平衡网络的负载,在选播服务中实现网络资源的优化利用,并且在传输服务数据流时,能减少时延及数据包的丢失.

关键词: 选播, 多协议标签交换, 流量工程, 最小冲突

Abstract: The network load balance of anycast service is studied. An anycast routing algorithm(ART) supporting multiprotocol label switching (MPLS) traffic engineering is presented. In ART, based on the minimum interference schema, MPLS constraint routinglabel distribution protocol (CRLDP) is used to establish a label switching path (LSP) from anycast server to client, meantime, the bandwidth is reserved on the LSP. Simulations show that ART can balance the load of networks, optimize the network resource utilization of anycast service, and reduce delay and data loss during data transfer.

Key words: anycast, multi-protocol label switching, traffic engineering, minimum interference
