建立了一个SBS(基于服务的系统,service based system)应用端到端性能评价模型,并在该模型的基础上提出了SBS应用动态资源分配方法,该方法通过将静态的初始资源分配和动态的资源分配方案调整相结合,能够适应用户访问行为的动态变化,保证SBS应用端到端性能.在SBS应用动态资源分配问题求解中,提出了服务吞吐量约束确定算法并在此基础上给出了SBS应用动态资源分配算法,该算法根据SBS应用吞吐量约束确定服务资源需求量并在此基础上通过起始服务到服务间的转移时间计算服务的资源分配时刻,从而能够在保证SBS应用端到端性能约束的同时提高资源利用率.实验验证了所提出的基于SBS应用端到端性能评价模型的动态资源分配方法的有效性.
An end-to-end performance evaluation model for SBS (service based system) application is established. Based on the model, a dynamic resource allocation method for SBS application is proposed. The method allocates static initial resource and dynamic Resource allocation scheme adjustment can adapt to the dynamic changes of user access behavior to ensure the end-to-end performance of SBS applications.In the SBS application of dynamic resource allocation problem solving, the service throughput constraint determination algorithm is proposed and on this basis is given The SBS applies a dynamic resource allocation algorithm. The algorithm determines the service resource requirement according to the SBS application throughput constraint and calculates the service resource allocation moment based on the SST application start-to-end transfer time so as to ensure the SBS application end to End performance constraints and improve resource utilization.The experimental results verify the effectiveness of the proposed dynamic resource allocation method based on end-to-end performance evaluation model of SBS.
