J. Quan · Computer Engineering and Applications Journal · 2007
Packet sampling technique is a key technique in high-speed network traffic measurement and network supervise.In this paper,by introducing into five parameters which are stratified characters,the number of strata L,stratified boundary,sample size assignment of each stratum and sampling strategy inside stratum,and through reconfiguring them and analyzing their theory simply,we improve the technology of stratified sampling.After then we use simple linear estimation method to inferring original information,further more by using Φ discrepancy examine method,we carry on the accuracy performance comparison between improved stratified sampling technique and other sampling methods form packet size distribution aspect.The result indicates that the accuracy performance of improved stratified sampling technique is well-above other sampling methods in packet size distribution aspect,and improves measured precision greatly.
