The Differentiated Service Architecture (DiffServ) is currently a popular research topic as a low-cost 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 large-scale network is used as a reference topology for studying the performance and effectiveness of the proposed services. It has five interconnected networks, which belong to five cities of Europe. The traffic generators are placed in the Athens network and the destination network is London for all TCLs, which is the longest path. Background generators(More)
