QoS Guaranteed Service Resource Co-Allocation and Management

Abstract

提出一种具有QoS保证的资源管理系统架构,理论分析表明,该系统架构能够较好地适应资源的动态性;其次将服务资源联合分配问题归化为MMKP(multiple-choice multiple-dimension knapsack problem)问题,并提出两种资源联合分配算法:最优解算法RA_BBLP和启发式算法RA_MHEU,实验结果表明,RA_BBLP保证求得最优解,可作为其他算法的参照系,而RA_MHEU收敛速度极快且所求出的解集接近最优,是一种理想的资源联合分配 算法.;A QoS guaranteed resource management system architecture is proposed. The theoretical analysis demonstrates that this system architecture can well adapt to dynamic behavior of resources; Secondly, service resource co-allocation problem is formulated as MMKP (multiple-choice multiple-dimension knapsack problem) and an exact algorithm RA_BBLP and a heuristic algorithm RA_MHEU are both presented. Experimental results show that RA_BBLP which ensures the optimal solution can be used as reference of other algorithms. However, RA_MHEU can obtain near-optimal solution at high speed, which is an ideal service resource co-allocation algorithm.
