Dynamic class selecting mechanism for guaranteed service with minimum cost over relative differentiated-services networks

The differentiated-services model has prevailed as a scalable approach to providing quality of service over the Internet. However, there are difficulties in providing the guaranteed service in terms of end-to-end systems since a differentiated-services network considers the quality of service of traffic aggregates due to the scalability. Furthermore, since the quality of service level may be time varying according to the network conditions in the case of the relative service model, it is more difficult to provide guaranteed end-to-end service when the path between two end systems includes several domains. Therefore, we study dynamic class selection mechanisms to guarantee the end-to-end quality of service for continuous media traffic with minimum networking cost over multiple differentiated-services domains.
