Routing and Traffic Engineering using MPLS

If one sticks too rigidly to one's principles, one would hardly see anybody.

Agatha Christie

Abstract

In this chapter, we present the applicability of MPLS for routing and traffic engineering for a set of representative real-world problems. Specifically, four problem classes are considered: 1) An integrated IP/MPLS environment for IP traffic engineering; 2) VPN traffic engineering/routing using MPLS; 3) multicast VPN traffic engineering with MPLS; and 4) a Voice over MPLS network, that is, an MPLS network where voice or multimedia real-time interactive service is provided.
