Multi-Level Profile-Meters for Service Differentiation in the Internet
نویسندگان
چکیده
The loss of fairness due to parallel TCP connections and the new UDP applications imply an architectural change in Internet’s structure. Service Differentiation is a new concept that defines simple methods to improve Quality of Service. The key modules of this model are the profile verifiers located in edge routers. They are charged of creating a tag for each packet based on this verification. This tag is used by core routers to help taking packet discard decisions and queue assignation. This paper describes the basics of the DiffServ architecture, presents a Multi-Level Token Bucket profile-meter and compares the performances of 2-level against multi-level approaches.

متن کاملAdvanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
متن کاملImproving Success Ratio in Multi-Constraint Quality of Service Routing
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...
