【摘要】 作为网格系统最重要构成部分之一的网络资源管理是对发展网格系统极具意义的技术。网格资源管理的内容范围广泛,包括了网络地点资源、网络组织资源、网络资源分配、网络资源调度等多方面。众多单一的网络资源能够通过网格管理系统集成一个整体,统一进行处理过度。先进的网络资源管理软件能够合理的配置资源、运用资源,对实现网络资源共享有着重要意义。本文以传统网格传统调度模型P2P-Grid为对象进行分析,针对现存的几个问题,提出构建新的调度模型Group-Grid。Group-Grid作为新的网格结构模型,能够根据网络资源提供者的不同将网格资源分为不同的小区,通过对各小区信息资源的快速搜索得到资源共享的目的。Group-Grid相比P2P-Grid,信息资源搜索速度更快,搜索过程带来的网络负担较小,并且容易调整,扩展性强。Group-Grid的资源预留策略不仅具有普遍性的预留策略,还具备了任务预留及其级别判定等多项功能,这些功能提高了模型资源预留成功度,有利于保留客户资源的QOS,最终实现模型在资源预留上的灵敏性和可靠性。除此之前,本文针对传统调度模型P2P-Grid无法平衡利用网络资源的缺陷,提出了改进式的网络资源预留计算法,即通过对即时任务快速的转化为预留任务,从而减少网络即时任务等待处理的时间,减轻网络任务处理的负担,最终实现网络资源共享高速度。本文通过相关模型的仿真数据说明,资源预留策略与即时任务处理速度相比提高了百分之十五的成功率。更多还原

【Abstract】 Resource management of grid system is one of the most important technologies, and it is of great theoretical practical value for the development of grid computing, location, organization, scheduling, allocation, confirming the discovery process, creating and preparing the necessary resources.It provides advanced management features and concepts, the clusters can be used as a single resource, administrator according to predetermined criteria, through resource management software, ensure the reasonable configuration of resource and use, achieves resources sharing.The main work of this paper is based on the traditional hierarchical scheduling model (P2P-Grid), proposes a new grid structure model (Group-Grid), to solve the traditional grid structure model in the surviving several main problems.This paper presents the model cf Group-Grid, is the grid resources according to the resource provider is divided into different compartments.Model of service discovery module to realize the purpose of quick search resources.Improved P2P-Grid using pan Hong Fa led to the network load increases, the disadvantage of the long search cycle.But also has strong expansibility, easy adjustment etc.Based on the structure model of resource reservation strategy, is available in the general reserve strategy based on task, put forward block, reservation cancel and reserved level concepts, so as to ensure the reliability and flexibility of the reservation of resources, and improve the success rate of Resource Reservation Reservation and customer QoS.In addition, the traditional resource reservation algorithm can balance the network overall resource utilization is insufficient, the existing balance tasks of resource reservation algorithm, this paper proposes an improved resource reservation algorithm, the immediate task is transformed into the reservation task submitted to the entire network to reduce the immediate task of the average waiting time, and can realization of whole network load balance, improve the utilization rate of resources in grid.The simulation results show that, the resource reservation strategy than the old strategy in the success rate improved by15%, in the cyber source utilization rate is improved by5%.更多还原
