Advanced MPLS Design and Implementation

Chapter 7.  MPLS Traffic Engineering

This chapter covers the following topics:

• The Need for Traffic Engineering on the Internet—. Through the deployment of traffic engineering, the traffic flowing across the service provider's backbone can be optimized, and traffic flows over underutilized paths can be optimized.

• Unequal-Cost Load Balancing via Metric Manipulation—. This technique allows routers to take advantage of load sharing over multiple unequal-cost paths to a given destination. This can be achieved by manipulating the parameters that determine the routing metrics for protocols such as OSPF, IS-IS, and EIGRP.

• Advantages of MPLS Traffic Engineering—. This section describes the features provided by MPLS traffic engineering that replicate and ...
