摘要
该文指出互联网技术的发展,带来了网络大流量业务的不断增加,特别是UDP业务数据急剧增加。由于UDP协议不具有拥塞控制能力,TCP协议具有拥塞控制能力,UDP数据极易阻塞网络链路,产生了严重的不公平性,影响了其他业务的进行。该文分析了路由器队列调度算法的原理,通过Opnet仿真,模拟了不同队列调度算法的拥塞状况,分析出采用正确的算法可以大大降低网络拥塞,提高网络传输的公平性。
Along with the Internet technology development,the network on the big flow increased business,especially the UDP business data has increased dramatically.Because the UDP protocol does not have congestion control ability,TCP protocol has congestion control ability,UDP data network link,extremely easy jam produces serious unfairness,the impact of the other business.This paper analyzes the principle of the router group scheduling algorithm,through the Opnet,simulating different queue scheduling algorithm,analyze the congestion in the right algorithm can greatly reduce congestion,improve the network transmission of fairness.
