Abstract:
1. A method of calculating transit traffic in a router including a plurality of interfaces transmitting or receiving a packet in a form of octets, comprising the steps of: (a) preparing a routing table having an interface column defining one of the plurality of interfaces which is interconnected to a router to which a packet is to be transmitted; (b) generating a transit traffic matrix of a subject interface whose transit traffic is to be calculated and initializing the transit traffic matrix; (c) obtaining an interface traffic matrix of the subject interface, the interface traffic matrix having packet and octet columns in which numbers of packets and octets received are stored respectively; (d) searching the routing table with respect to the interface traffic matrix obtained to locate an entry of the routing table matching with the interface traffic matrix to obtain a value of the interface column of the located entry; (e) determining whether or not the obtained value of the interface column corresponds to the subject interface; and (f) adding, if the obtained value of the interface column is determined corresponding to the subject interface, values of the packet and octet columns of the subject interface in the interface traffic matrix to the transit traffic matrix.
