Abstract

Abstract:

For achieving more effectively dynamic resource allocation, a dynamic bandwidth allocation algorithm is proposed using complete partitioning (CP) technology in a single communication link by analysing dynamic bandwidth allocation in a common link. On the basis of forecasting the influence of call-blocking probabilities on the transient response,the algorithm proposed in this paper controlls call-blocking probabilities proportion between different Classes-of-Service (CoSs) of non-stationary traffic with variable size bandwidth requests, consequently achieving optimal utilization of the bandwidth. Simulation shows that the capacities can be dynamically allocated in a nonstationary traffic environment by adopting the proposed algorithm. And it can also allocate the bandwidth much more effectively,while enhancing greatly the utilization ratio of the bandwidth, reducing the average polling time.

Key words: proportion, dynamic bandwidth allocation, call-blocking probabilities, controlling
