The Differentiated Services (DiffServ) architecture has been proposed as a scalable solution for providing service differentiation among flows. Towards the enhancement of this architecture, new mechanisms for admission control and a new set of network services are proposed in this paper. Each network service is appropriate for a specific type of traffic and is realized through its own network mechanisms, which are the Traffic Classes. Traffic Classes provide the traffic handling mechanisms for each Network Service and are composed of a set of admission control rules, a set of traffic conditioning rules and a per-hop behavior (PHB). Different traffic-handling mechanisms are proposed for each network service and are implemented with the use of the OPNET simulation tool. A large-scale network is used as a reference topology for studying the performance and effectiveness of the proposed services.
