Dynamic Admission Control for Quality of Service in IP Networks

The goal of admission control is to support the Quality of Service demands of real-time applications via resource reservation in IP networks. In this paper the authors introduce a novel Dynamic Admission Control (DAC) mechanism for IP networks. The DAC dynamically allocates network resources using the previous network pattern for each path and uses the dynamic admission algorithm to improve bandwidth utilization using bandwidth brokers. The authors evaluate the performance of the proposed mechanism through trace-driven simulation experiments in view point of blocking probability, throughput and normalized utilization.
