Abstract
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 Differentiated Services (DiffServ) paradigm is still one of the major outcomes of the research community toward the provision of QoS to individual customer needs and applications. This paper addresses the definition and deployment of specific network services in a DiffServ environment. We reuse and extend the fundamental concepts of the Expedited Forwarding and Assured Forwarding per hop behaviors in order to define four new network services, apart from the well known Best Effort one, which introduce a specific traffic handling implementation along with an Admission Control methodology. These are analyzed and simulated in the paper in order to evaluate their performance and confirm the correctness of their fundamental principles.
