摘要
流量分配是影响并行入侵检测系统实时性的重要因素。首先提出了一种以局部时间内探测节点的负载平衡为目标,综合考虑探测节点的负载和处理能力的动态流量分配策略;然后通过引入负载平衡的粒度、益处估计,提出了一种动态负载平衡策略,达到了全局时间内探测节点的负载平衡;最后通过实验分析表明该策略是有效的。
flow-distribution is a factor influential to the efficiency of parallel IDS.First of all,this thesis propounds a comprehensive strategy based on the load and performance of the sensors,which aims to get the load-balance of sensors in a limited time. Then through the introduction of load-balancing granularity and benefits evaluation,a dynamic load-balancing strategy is presented, causing load-balance of sensors to IDS in a whole time.Finally,the efficiency of it can be showed through experiment.
