Abstract

Abstract:

According to the demand on the admission control of softswitch-based clustered media server, a new dynamic quota-based admission control algorithm was proposed. A sub-negotiation process was presented with the algorithm. Meanwhile, not only the advantages of quota-based algorithm was inherited but new ideas was adopted in the new algorithm. Simulations have been conducted on the Petri net model. The result shows that this algorithm can be of excellent performance. In order to find the optimal size of each resource section in real time, two approximation analysis methods were proposed. It can be seen from experiments that these methods can be used to get sub-optimal quota values quickly and effectively. These two approximation analysis methods will play important roles in implementation of system algorithms.
