由分析在包延期上强制的生气交通(CT ) 的效果,一个改进路径能力测量方法, pcapminp 算法,被建议。与这个方法,路径能力被基于测量最小的包对延期过滤探查样品测量。最小的包对延期的 measurability 被模拟也分析。结果证明当与 pathrate 作比较时,如果 CT 负担是轻的, pcapminp 和 pathrate 有类似的精确性;但是在重 CT 的箱子中装载, pcapminp 比 Pathrate 更精确。当 CT 负担到达 90% 时, pcapminp 算法有 5% 仅仅测量错误,它是 10% 比 pathrate 的低算法。在任何 CT 负担层次, pcapminp 算法的探查费用是比 pathrate 的小的二大小,并且测量持续时间是比 pathrate 算法的短的一大小。
By analyzing the effect of cross traffic (CT) enforced on packet delay, an improved path capacity measurement method, pcapminp algorithm, was proposed. With this method, path capacity was measured by filtering probe samples based on measured minimum packet-pair delay. The measurability of minimum packet-pair delay was also analyzed by simulation. The results show that, when comparing with pathrate, if the CT load is light, both pcapminp and pathrate have similar accuracy; but in the case of heavy CT load, pcapminp is more accurate than Pathrate. When CT load reaches 90%, pcapminp algorithm has only 5% measurement error, which is 10% lower than that of pathrate algorithm. At any CT load levels, the probe cost of pcapminp algorithm is two magnitudes smaller than that ofpathrate, and the measurement duration is one magnitude shorter than that ofpathrate algorithm.
