Improving the IP routing table update using clusetring technique

Abstract

Link state IP protocols like OSPF and IS-IS work upon network state advertisements. Link state packets travel all over the network, advertising recent failure or changes in the network. It is IP router responsibility to execute the complex updating process which includes recalculating shortest paths and updating central and local forwarding tables. Since forwarding tables must be updated for forwarding new arrival packets, forwarding received packets during the updating process is one of the most critical issues. There have been several researches in the way of updating forwarding tables for achieving less packet loss ratio and faster packet forwarding statistics during updating process. This paper presents an updating method based on clustering the traffic which has been recently received by the router. Each cluster represents a set of network prefixes with almost the same priority for being updated. Our experimental results shows how clustering could decrease the packet loss ratio during updating process.
