Chapter 1. Understanding Traffic Engineering with MPLS
Multiprotocol Label Switching (MPLS) has been getting a lot of attention in the past few years. It has been successfully deployed in a number of large networks, and it is being used to offer both Internet and virtual private network (VPN) services in networks around the world.
Most of the MPLS buzz has been around VPNs. Why? Because if you're a provider, it is a service you can sell to your customers.
But you can do more with MPLS than use VPNs. There's also an area of MPLS known as traffic engineering (TE). And that, if you haven't already figured it out, is what this book is all about.
