摘要 为了解决多传感器信号传输中端到端TCP协议存在的如高丢包率、带宽不稳定、动态拓扑以及存在由于多信号同时传输产生拥堵,导致网络传输性能降低等问题,提出了一种基于多传感器信号传输网络的传输控制协议M-TCP.M-TCP采用了一种基于瓶颈节点信息反馈的新的流量控制机制,取消了慢启动探测网络带宽阶段,在连接建立后便采用较理想的发送速率进行数据传输,成功避免了传输振荡.结果表明,M-TCP在数据吞吐量、丢包率和传输延迟等方面具有较大优势,能够很好地提升传输网络的传输性能. In order to solve such problems as high packet loss rate,unstable bandwidth,dynamic topology and network performance degradation caused by the congestion due to simultaneous multi-signal transmission in the end-to end TCP protocol in the multi-sensor signal transmission(MST) process,a transmission control protocol M-TCP was proposed based on MST.A novel flow control mechanism based on the information feedback of bottleneck node was adopted in the M-TCP,and the slow start phase to detect network bandwidth was cancelled.After the connection was established,an ideal transmission rate was adopted for the data transmission,which could successfully avoid the transmission oscillation.The results show that the M-TCP has great advantages in such aspects as data throughput,packet loss rate and transmission delay,and can well enhance the transmission performance of transmission network.
