Performing Admission Control Concurrently in Core-stateless Networks
In this paper, the authors propose a concurrent admission control scheme for the QoS sensitivity traffic in core-stateless networks. In this scheme, the ingress router of core-stateless network domain is capable of performing admissibility test in concurrent for requests by per-assigning core-link resource to each edge routers. Then, they introduce a novel two phase token passing mechanism to adaptively optimize the proportion of bandwidth dividing among contending edge routers according to the dynamic of their traffic. In addition, they adopt a measurement based admission decision-making criterion to gain the benefit of high utilization of statistical multiplexing.
