A system and method for exactly estimating a volume of traffic is provided when packets are transferred within the network. The system and method receive data packets from clients through a plurality of router-for-clients, and creating a flow information packet for estimating information about a flow, transfer the data packets and the created flow information packet to the destination router-for-client via a router-for-relay, calculate information about the traffic of a flow at the destination router-for-client through the flow information packets transferred from the router-for-clients, and estimate a volume of the traffic. Thus, the system and method can estimate the volume of the traffic on the network with respect to the aggregated flow defined by the router pair connected to the terminal or the external network when the traffic is actually introduced into the network, instead of the flows of each terminal and each destination.

System and method for estimating flow-specific traffic volumes

A hybrid channel assignment method comprising the steps of negotiating among routers to select one router to act as a central server; collecting, at the selected router, information on an entire network transmitted from the other routers, and assigning channels based upon the information on the entire network; and reassigning channels of respective routers based upon dynamically-changing traffic characteristics. The hybrid channel assignment method can assign channels using both centralized processing and distributed processing in order to ensure optimally correct channel assignment consistent with present traffic characteristics. This as a result can prevent network resources from being wasted and also increase network capacity, thereby optimizing effective use of the network resources.
