US 8,284,697 B2 · System and method for estimating flow-specific traffic volumes

Abstract

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.

Dependent claims

A system for estimating flow-specific traffic volumes of combined layer 2/layer 3 (L2/L3) based routers, which is used to exactly estimate a volume of traffic introduced into a network, the system comprising:

a plurality of router-for-clients, which creates or consumes the traffic;
a router-for-relay, which transfers a packet to the plurality of router-for-clients;
and
a simple network management protocol server, which receives information about the traffic, which is measured and transferred, from each router-for-client and forms information about distribution of the entire traffic of the network,
wherein each router-for-relay receives a data packet from a client, creates a flow information packet for estimating information about the received flow, and transfers the data packet and the flow information packet to a destination one of the router-for-clients via the router-for-relay.
