TCP/UDP业务拥塞问题的研究

TCP/UDP traffic congestion problem

随着UDP(User Datagram Protocol)业务的增加,网络拥塞出现了新问题。当网络发生拥塞时,UDP业务非公平的占有网络带宽,导致TCP业务性能下降。文中提出了基于MPLS显式路由机制和流量中继主干线解决TCP/UDP业务之间的不公平竞争网络带宽资源问题的策略,并进行了网络仿真实验。仿真结果表明:用基于严格显示0路由的流量中继主干线来分离TCP和UDP业务流,TCP/UDP业务的拥塞状况有所改善,业务性能有较大提高。

With the increase of UDP traffic, a new problem with network is congestion. The appearance of network congestion, UDP traffic allocating unfairly the network bandwidth leads to fall of TCP service performance. The paper proposes a scheme based on MPLS explicit routing and traffic trunk to solve the unfairness in allocating the network bandwidth among TCP and UDP, and network simulations experiment is worked. The result of simulations shows： on the conditions of the strict explicit routing trunks separate the traffic of TCP and UDP , congestion state of TCP/UDP traffic are improved and performances are raised.
