摘要
快速准确的链路状态估计是基于网络的拥塞控制算法中一个重要的组成部分。提出了一种链路状态快速探测算法A2DPM,通过对报文头部标识字段进行多个哈希映射,加速链路状态信息的探测,只需少量的探测报文即可得到准确的链路状态信息,因此会话发起端能够迅速感知链路上的拥塞,并相应调整其发送速率,以实现网络的最优化传输。
Accurate and fast estimation of link price is the key component in network-based congestion control schemes. A fast estimation method A2DPM is presented. Multiple hashes on IP identifier of packet header are adopted to accelerate the side information transmitting, so accurate estimation of maximum price on the flow forwarding path can be got just after a small number of probe packets are received, and the sender is capable of reacting to congestion more quickly, making networks optimally utilized.
