Study on Packet Sampling
分组采样技术研究

With the improvement of bandwidth,packet sampling,as an important technique of traffic measurement,is getting more and more attention. Because in high speed networks,statistics of all the arrived packets is very expen- sive. Through packet sampling,the measurement cost is largely decreased,which makes the measurement more scal- able. In this paper,a number of packet sampling techniques are analyzed systemically,focusing on their basic idea,ac- curacy,and effectiveness. Furthermore,some advices are presented to improve existing problems.
