Multi-protocolos sobre ATM, interoperabilidade e gerência: um estudo de caso

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Computação.Este trabalho consiste no estudo e na realização de experimentos com o Multi-Protocolo sobre ATM. São apresentados testes de interoperabilidade entre equipamentos com suporte a MPOA de diferentes fabricantes. Nos experimentos de conformidade as características dos equipamentos são confrontadas com as declarações de conformidade da implementação do protocolo MPOA. Para mostrar os benefícios do MPOA, foi implementado um ambiente de teste especifico para realizar experimentos de avaliação de desempenho em ambientes

Did MPOA achieve its objective?

Layer 3 switching is a subject vehemently discussed in the networking community. In addition to a number of manufacturer-specific approaches, Multi-Protocol Over ATM (MPOA) and Multiprotocol Label Switching (MPLS) are the most important examples of this technology. MPOA [1,2] was released in 1997 by the ATM Forum; MPLS [3,4] is a collection of IETF Internet drafts. This paper presents the concept of MPOA and reports on experiences resulting from the practical use of MPOA implementations from several manufacturers. The report also discusses the areas in which MPOA can be appropriately employed. Two years after the release of the MPOA standard, time has come to critically discuss the original objective of MPOA, to examine the implementations of several manufacturers and to compare MPOA with other solutions and their objectives.
