The Differentiated Service Architecture (DiffServ) is currently a popular research topic as a lowcost method to provide Quality of Service to the different applications in the Internet. This paper addresses the definition and deployment of specific network services in a DiffServ environment. The proposed network services are described, while our main focus(More)
Differentiated Service Model (DiffServ) is currently a popular research topic as a low-cost method to bring QoS to today’s Internet, especially in the backbone. The DiffServ architecture consists of two key components: traffic conditioning at the edge and Per Hop Behavior (PHB) at the edge and the core. Traffic Conditioners contain various elements such as(More)
A vital requirement for next generation IP networks is the provision of services with differentiated behavior and characteristics. The basic reason for that is the need to provide Quality of Service (QoS) to the different types of user traffic produced by applications that are different in nature and behavior, analogously to the IP network services. The(More)

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(More)
