摘要/Abstract

摘要：

提出了一种在单链路中采用完全划分技术的动态带宽分配算法，该算法在预测呼叫阻塞率对过渡反应影响的基础上，对链路中具有可变带宽需求的非固定流量的不同服务级间的呼叫阻塞率的比例进行控制，从而实现带宽的最佳利用．仿真表明，所提出的算法能够有效地将容量动态地分配到非固定流量环境中，提高了带宽利用率，缩短了平均轮询时间．

关键词: 比例, 动态带宽分配, 呼叫阻塞率, 控制

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
