摘要
通过分析传统 TCP算法的局限性 ,讨论 TCP Vegas、TCPW两种基于源端实时带宽测量拥塞控制算法的原理以及带宽分配的公平性 ,结合主动队列管理技术 ,提出一种基于加权缓存区容量分配 RED算法 .理论分析和仿真实验表明该算法提高了带宽分配的公平性 ,保持了网络的高吞吐量 ,并实现服务 Qo S保证 .
Analysed the limitation of traditional TCP algorithms and discusses the elements of TCP Vegas and TCPW, which are based on real-time bandwidth measurement and the fairness of bandwidth allocation.Combined with active queue management scheme,an enhanced RED algorithm based on weighed buffer capacity allocation was introduced.Theoretic analysis and simulation experiments show that this algorithm improves the fairness of bandwidth allocation,maintains high throughput and assures QoS of service.
