Abstract
Differentiated-services model has been prevailed as a scalable solution to provide quality of service over the Internet. Many researches have been focused on per hop behavior or a single domain behavior to enhance quality of service. Thus, there are still difficulties in providing the end-to-end guaranteed service when the path between sender and receiver includes multiple domains. Furthermore differentiated-services model mainly considers quality of service for traffic aggregates due to the scalability, and the quality of service state may be time varying according to the network conditions in the case of relative service model, which make the problem more challenging to guarantee the end-to-end quality-of-service. In this paper, we study class renegotiating mechanisms along the path to provide the end-to-end guaranteed quality of service with the minimum networking price over multiple differentiated-service domains. The proposed mechanism includes an effective implementation of relative differentiated-service model, quality of service advertising mechanism and class renegotiating mechanisms. Finally, the experimental results are provided to show the performance of the proposed algorithm.
