IP Traffic Engineering

As late as 1842 a train was started only when sufficient traffic was waiting along the road to warrant the use of the engine.

Abstract

In this chapter, we discuss traffic engineering for IP intra-domain networks. The role of traffic engineering is to optimize an operational network so that performance requirements are met, yet network resources are well utilized. Traffic engineering is an essential component of IP intra-domain operational networks, especially if the network is large. The main goal of IP traffic engineering is to determine link metrics (weights) in an optimal manner so that the primary goal for the network such as reducing congestion or delay is met through efficient traffic ...
