摘　　要：在分析服务器集群负载平衡的特点的基础上,针对集中式负载平衡调度,提出了LTI算法,并给出算法实现的过程和算法效率评估的具体方法。为了解决该算法中接近临界状态时性能急剧下降的问题,进一步提出改进算法LTI+,以判别和避免集群进入临界状态。此算法有效地提高了分布式网络资源的利用率。The paper put forward of algorithm of LTI for the load balance by analysising characteristic of the server group load balance.The implementation process of the algorithm and efficiency evaluating method are put forward. Further, improved algorithm of LTI+ is proposed in order to avoid a sudden descending performance on critical status which occurred in algorithm of LTI. Algorithm of LTI+ can distinguish and avoid critical status of server group and rapidly improve efficiency of distributing network.
