Abstract
In this paper we propose a scalable admission control scheme for the QoS sensitivity traffic in DiffServ domains. In our scheme, the ingress routers perform admissibility test in a fully distributed and parallel fashion for requests based on our resource per-assigning mechanism.Then, we introduce a novel two phase token passing mechanism to adaptively optimize resource per-assigning among contending edge ronters in proportion to their traffic.In addition, we adopt a measurement based admission decision-making criterion to gain the benefit of high utilization of statistical multiplexing. Our simulation results indicate that even under very high request load it is possible to perform admission control and resource allocation in parallel without suffering in terms of response time, packet loss rate, or utilization.关键词
