document: Traffic engineering with traditional IP routing protocols Traffic engineering involves adapting the routing of traffic to network conditions , with the joint goals of good user performance and efficient use of network resources . We describe an approach to intradomain traffic engineering that works within the existing deployed base of interior gateway protocols , such as Open Shortest Path First and Intermediate System-Intermediate System . We explain how to adapt the configuration of link weights , based on a networkwide view of the traffic and topology within a domain . In addition , we summarize the results of several studies of techniques for optimizing OSPF/IS-IS weights to the prevailing traffic . The article argues that traditional shortest path routing protocols are surprisingly effective for engineering the flow of traffic in large IP networks
