Na Internet, serviços garantidos de Qualidade de Serviço (QoS) são cada vez mais exigidos, e a Internet Engineering Task Force (IETF) está desenvolvendo intensamente os documentos de especificação para os serviços de QoS. Esta visão geral detalha os fundamentos técnicos que sublinham o conteúdo dos documentos de especificação desenvolvidos pela IETF para Serviços Diferenciados (DiffServ) – para fornecer serviços de garantia de QoS nas grandes redes IP – e Policy Framework – para gerenciar redes compatíveis com DiffServ. As redes IP com DiffServ consistem em roteadores de limite e roteadores internos. Esses roteadores são compostos de classificadores de pacotes e funções de marcador, modelador e policiamento. Muitos fornecedores desenvolveram roteadores compatíveis com DiffServ com interfaces gigabit. Um exemplo de implementação de um roteador compatível com DiffServ e uma demonstração de um serviço QoS usando este roteador são apresentados aqui. Espera-se que o Quadro de Políticas seja uma das soluções de gerenciamento promissoras para cooperar e gerenciar muitos roteadores compatíveis com DiffServ. Um experimento que adota o Policy Framework para uma rede compatível com DiffServ também é descrito.

Abstract: On the Internet, a Quality of Service (QoS) guaranteed services are increasingly being demanded, and the Internet Engineering Task Force (IETF) is developing the specification documents for the QoS services intensively. This overview details the technical rationales underlining the contents of the specification documents developed by the IETF for Differentiated Services (DiffServ)--to provide QoS guarantee services in the large IP networks-- and Policy Framework--to manage DiffServ compliant networks. The IP networks with DiffServ consist of boundary routers and interior routers. These routers are composed of packet classifiers and marker, shaper, and policing function. Many vendors have developed DiffServ-compliant routers with gigabit interfaces. An example of an implementation of a DiffServ-compliant router and a demonstration of a QoS service using this router are presented here. The Policy Framework is expected to be one of the promising management solutions to co-operate with and manage many DiffServ-compliant routers. An experiment that adopts the Policy Framework to a DiffServ compliant network is also outlined.
