【摘要】 在已有的主动网络拥塞控制机制(ACC)中,通过丢包的方式缓减拥塞。TCP拥塞控制机制起主导作用,但不能满足现有网络环境要求。该文提出一种改进的ACC算法,该算法将拥塞控制参数嵌入到每个主动包中,通过驻留在主动路由器中的拥塞控制代码,对参数进行相应修改,从而达到拥塞预防和控制的目的。仿真结果表明,该方法具有较好的网络带宽利用率和公平性,丢包概率接近0。更多还原

【Abstract】 Active Network Congestion Control(ACC) uses dropping packets to relax congestion which can not satisfy the current network. This paper puts forward an improved ACC algorithm which can avoid and control congestion through modifying the congestion parameters carried with every active packet by congestion control codes in active routers. Experimental results show that the algorithm keeps high efficiency, good fairness, and rare packet dropping.更多还原
