摘　　要：在作者提出的一种新的Web集群体系结构的基础上,详细讨论了防止系统过载,实现区分服务的多级控制策略与机制.给出了区分服务接纳控制的系统模型及其数学描述,然后提出了基于事务的区分服务接纳控制策略.实验结果与理论分析表明:在系统过载时能有效保证系统的稳定性,高优先级任务得到较好的服务,在某些情况下比基于会话的接纳控制效率好10%.Based on the new web clustering architecture which the author presented, the preventing system overload, and the multilevel control policy and mechanism of implementing the differentiation service are discussed in detail. The system model and its mathematics descriptions are brought forward, and then the differentiation service admission control policy based on session is presented. The results of experiment and theory analysis indicate that when the system is overload, its stability can be efficiently ensured, the advanced priority task can get better services and in certain case, our control tactic will more efficient 10% than the admission control based on session.
