网格资源分配中的自动协商机制研究

提出有监督的网格自动协商机制,实现了网格中用户需求和资源服务的动态调节及匹配.在该机制中,用户代理作为用户利益的维护者,在用户需求基础上,用户代理与资源不断调整自身的利益需求,最终实现用户需求和资源服务的一致.利用GridSim工具包建立了网格自动协商机制模拟平台.模拟实验表明,此机制能够消除用户需求和资源服务之间的冲突,并在一定范围内保持较高的协商效率.

Automated Negotiation for Resource Allocation in Grid

An automated negotiation mechanism for resource allocation in grid is presented. The mechanism supports the dynamic adjustment and matching of the user's requirement and the resource service. In the mechanism, user's agent safeguards his interest. User's agent and resource gradually adjust theirs interest, change their requests to make the user's complex requirements match the resource services. This negotiation process is supervised by the negotiation-tunnel agent. At last, a simulation environment is established based on the GridSim toolkits and the simulation experiments indicate that the mechanism can eliminate the misfit between the user's requirement and the resource service, and can keep a fine efficiency within certain range.
