试验IP网组播丢包问题研究

摘要

As a highly efficient network transfer technology, IP muhicast is widely applied in data transfer, multimedia and many other communication fields. Packet loss has been found to happen because of problems in network environment, protocol setting or port flow. The network protocol on tracking ＆ control ship and packet loss problem are analyzed, and several solutions are provided,which are proved to be effective.%IP组播技术实现了IP网络中点到多点的高效数据传送,因为组播能够有效地节约网络带宽降低网络负载,所以在实时数据传送和语音图像数据等诸多方面都有广泛的应用。由于传输环境、协议配置或端口流量等原因,在实际应用中可能会发生传输数据丢失的现象。针对组播传输丢包问题,分析了某类试验IP网络协议及组播传输环境特点,提出了几种解决方案并进行了试验验证。
