Arquitetura Pseudowire: uma infraestrutura multiserviço

Abstract

This work aims to study the PWE3 technology, the types of native emulated services, the present PSN models as well as the methodologies under different Drafts and techniques that have improved the model in Backbone transport environments. Thus, the work provides in formation on the evolution of the switching systems so that one can have an insight into the speed with which new technologies have emerged and others become obsolete, as well as a margin about the problematic faced by ISPs and customers regarding the evolution and spending on new infrastructures. The types of emulations and transport that can be used to obtain or maintain the legacy service are mentioned. It discusses the Pseudowire emulation through MPLS, TDM, and L2TPv3 mechanisms and completing is explained about its applicability in several points of a telecommunications network while contributing in the network convergence process.
