目前基于自拥塞理论的网络可用带宽主动探测方法,一般都要发送大量的探测包串,在对网络可用带宽进行探测的同时,可能会干扰网络的正常通信。这一方面增加了网络负载,另一方面也增加了算法的复杂性。针对此问题,提出使用幂级数变时隙探测包替代等时隙探测包,期望通过新的探测方法在不失估测精度的前提下,用更少的探测流量获得更快的自拥塞集聚时间,从而提高可用带宽的探测效率。实验表明新的探测算法可以达到比传统算法更好的效率。
At present, based on the self-congestion theory, the available bandwidth active probing method of the network usually sends a large number of probe packets, which may interfere with the normal communication of the network while probing the available bandwidth of the network. On the one hand increased network load, on the other hand also increased the algorithmic complexity. In view of this problem, we propose to use the power series variable time slot detection packet instead of the equal time slot detection packet, expecting to achieve faster self-congestion aggregation with less probing flow without loss of estimation accuracy by using the new detection method Time, thereby improving the detection efficiency of available bandwidth. Experiments show that the new detection algorithm can achieve better efficiency than the traditional algorithm.
