Research on New Routing Technology in WDM Network System

Abstract

In this paper, a new routing design is presented. Interior gateway Protocols (IGPs), particularly Open Shortest Path First (OSPF), uses a simple single metric component, cost, which is based on the bandwidth of the link. Most large IP networks run Interior Gateway Protocols (IGPs) such as Open Shortest Path First (OSPF) or Intermediate System-Intermediate System (IS-IS) that select paths based on static link weights. Enhanced Interior Gateway Routing Protocol (EIGRP) is slightly more aware of the link characteristics in that it calculates a metric based on cumulative delay (delay is simply an arbitrary assigned value) and the minimum bandwidth value encountered between the source and destination. Routing technology can better the network operation efficiently.
