After this introduction, we then introduce and discuss some of the new applications of MPLS networks such as traffic engineering and virtual private networks.
After an introduction to MPLS, we explain the basic premise behind why MPLS-enabled networks need to be managed to provide scalable, usable, and most importantly profitable MPLS networks. Given ...
