A SYSTEM FOR CONTROLLING THE FLOW OF THE IP NETWORK AND THE METHOD THEREOF

摘要

A system for controlling the flow of the IP network and the device and method thereof, includes the user flow policy server unit, the IP LAN network element, the up-link flow control unit and down-link flow control unit. The user first uses the default flow control policy, and then collects the flow data on the link, and determines the link which needs to control the flow, generates and sends down the command of the user flow control policy, and the user flow control unit updates the user flow control policy database to look for the matched user flow record according to the policy command, if it finds, updates the parameter of the user flow record, if it doesn't find, uses the default policy, and generates the user flow record to control the user flow according to the user control policy. This invention improves the server QoS of the IP LAN telecommunication , and reduces the influence of the flow attack to the IP LAN.
