一种改进的OPBM快速算法
An Improved Algorithm for the OPBM Algorithm
【摘要】 在对大规模通信网络中的最优带宽分配算法(OPBM)的实现及其性能的研究过程中发现影响呼叫阻塞概率(CBP)的因素包括两部分预留带宽的影响和非预留带宽的影响,而预留带宽对CBP的影响要大过非预留带宽的影响。基于此发现,该文在OPBM方法的基础上,提出了一种改进式的OPBM算法,与原算法进行了对比,改进OPBM算法的误差很小并且运算速度加快。
【Abstract】 In this article,we focus on researching computer process of optimal path bandwidth management (OPBM)for large-scale telecom networks and find that the factors which influence call blocking probability includes two aspects:the influences for CBP of reserved bandwidth and non-reserved bandwidth.An improved algorithm is presented in the article based on the algorithm of OPBM.We compare the performance of this improved algorithm with that of original OPBM algorithm and conclude that the former makes a great increase in speed with little error.
【Key words】 OPBM; call blocking probability; bandwidth allocation; optimization;
