XCP协议是一种针对高带宽时延乘积网络的Internet拥塞控制体系,其算法的关键是将拥塞控制参数嵌入每一主动数据包中,然后根据途经路由器的网络拥塞状况对相关参数进行修改,以达到预防拥塞的目的.本文分析了路由器参数对突发网络的性能影响,证明了路由器参数设置应该是优化效率与鲁棒性的折中,并提出了一种针对突发网络的自适应算法,实验结果表明,新算法明显优于原算法.
XCP協議是一種針對高帶寬時延乘積網絡的Internet擁塞控製體繫,其算法的關鍵是將擁塞控製參數嵌入每一主動數據包中,然後根據途經路由器的網絡擁塞狀況對相關參數進行脩改,以達到預防擁塞的目的.本文分析瞭路由器參數對突髮網絡的性能影響,證明瞭路由器參數設置應該是優化效率與魯棒性的摺中,併提齣瞭一種針對突髮網絡的自適應算法,實驗結果錶明,新算法明顯優于原算法.

XCP protocol is a new system in Internet congestion control for high-bandwidth delay . The key of this algorithm is to embed the main parameters of congestion control into each packet, and then to prevent congestion by controlling these parameters according to the congestion condition of the routers. The paper analyzes the influence of the router parameters to the performance of the instable Network,demonstrates that router parameters should be a tradeoff of the efficiency and robustness,and finally puts forward an adaptive algorithm for instable network,which is evidently superior to the original one shown by the experiments.
