Design and Implementation of Flow Monitoring System Using a New Flow Record on QoS Router

摘要

In this paper, a flow analysis and monitoing system uging a New flow Record is introduced. This system is designed to harvest real-time, billing-accurate information on any combination of application, session or user traffic- in the very core of the network. Since the emergence of IP networking, operators have wanted visibility into individual flows within the network. Conventional methods such as cflowd rely on sampling and can only report on a small number of flows. To date no scalable way to accurately view individual flows deep within the network has been made available- except for this system. we present the system collects all flow information which sampled and loosely extrapolated but accurate and updated for each and every packet.
