摘　　要：设计了在大规模异构网络中对不大于200个用户数量进行可靠多播数据传输协议SRMTP。SRMTP采用流式分趟传输模式、基于接收端的传输状态管理、发送端询问接收端应答的集中报错机制等技术,在已有可靠多播协议的基础上简化协议规程,提高了协议执行效率。在实际环境中的性能测试结果表明SRMTP可以提供高效、可靠的多播数据传输服务。In this paper, a stream-based reliable multicast transport protocol （SRMTP） is designed, which is suitable for those applications in which the number of receivers is relatively small. SRMTP provides effective one-to-many reliable data transfer service by a series of approaches, such as stream-based transfer mode by pass, receiver-initiated loss recovery mechanism, NAK aggregation. As protocol control flow is simplified, the efficiency of SRMTP is improved. The performance of SRMTP is examined in a real environment and the result shows that SRMTP can support reliable data transport in a high throughput.
