Programmable Remote Traffic Monitoring Method Using Active Network Approach

As the Internet has become an infrastructure for the global communication, a network failure and a quality degradation have become a serious problem. In order to solve the problem, a network monitoring system which monitors the traffic of Internet in real time is strongly desired. Traffic monitors which collect the statistics from captured packets play a key roll in the system; however, they are not flexible enough for being used in the rapidly changing Internet. The traditional approach such that a new traffic monitor is developed for a new requirement results in a long turn around time of the development. Therefore, we have proposed a flexible network monitoring system which consists of programmable traffic monitors. Traffic monitors are made programmable by introducing active network techniques; therefore, we call the network monitoring system as the active monitor network. This paper describes the implementation and evaluation of the active monitor network.
