Abstract

The invention discloses a sketch based data center network flow analysis method. The method comprises the steps of receiving a network flow statistic data package in real time or off-line; determining the flow amplitude of the data package according to analyzed network flow counting data package header information to serve as the sketch input; performing real-time flow analysis based on sketch. According to the method, the prior sketch based flow statistic algorithm is innovated, a sketch algorithm based on probability selection is put forward, and CM and CU algorithms are selected according to the probability; a partition sketch algorithm is raised, and partition can be performed on sketch when different types of network flows are processed, so that the accuracy is improved, and the complexity is reduced; besides, updating information is added into information discounted according to the ratio through a real-time moving average algorithm, according to the real-time moving method, the older the information is, the more information discounts are, so that space is saved, and flow sudden change situations can be recorded.
