Abstract :
This paper proposes the TPED MBAC (two-phase edge-to-edge distributed measurement based admission control) mechanism that provides the guarantee of user QoS requirements and the fairness of blocking probability between flows traversing different path lengths in large IP networks. The proposed mechanism has two provisioning phases, the quantitative provisioning phase and the qualitative provisioning phase, in admission control and performs WRR scheduling based on the hop counter for probing packet transmission. Additionally, the proposed mechanism uses the optimized probing packet rate instead of the peak rate. For the performance evaluation of the proposed mechanism, we present simulation results in terms of the fairness of blocking probability and the loss probability using the ns-2 simulator
