用于3G网络监管的负载平衡方法及其稳定性分析

Dynamic Load Balancing and Stability Analysis for 3G Network Security Management

为了处理3G网络监管系统中产生的海量数据,该文提出一种负载平衡算法.在分布式动态负载平衡模型的基础上,采用负载选择分配策略设计了随机转移负载的时延模型,并给出了增益系数的取值.根据控制论的相关理论和方法对该算法进行稳定性分析,验证了本算法符合3G监管需求,并据此修正了多余负载转移的百分比公式.

To deal with massive data produced by the 3G network security management system,a load balancing algorithm is developed.Base on Hayat＇s dynamic load balancing model for a distributed system,a stochastic load-transfer delay model is proposed using selective load allocation.The optimal value of the load balancing gain is given via simulation.Stability of the load balancing method is a key issue in parallel computation. Unstable behaviors can greatly influence the performance.By analyzing stability of the improved algorithm using the control theory and the related techniques,a formula for the percentage of excessive load is revised to satisfy the demand of 3G-network security management.
