RESEARCH AND APPLICATION OF DISTRIBUTED SAMPLING MEASUREMENT SYSTEM BASED ON MASK MATCHING FOR IP NETWORK TRAFFIC

摘要

This paper provides an architecture of the distributed sampling measurement system based on mask matching,and the system is divided into three layers which includes message collecting,sampling and saving.Furthermore we refer to distributed collecting measurement method and give a distributed sampling measurement algorithm (DSMA).Then we use the distributed sampling measurement system and DSMA to make sampling measurement for the export traffic of campus network and estimate the original traffic during a period of time from sampling message.By comparing the differences between the result of sampling measurement and the traffic message of firewall in campus network,it can be proved that the result of sampling measurement conforms to the fact.
