【摘要】 随着当今Internet技术日渐成熟和第三代互联网的提出,网格计算的设想与实践已不再遥远,网格计算的核心是对异地异构资源非集中性控制的资源协调,通过通用开发的协议和接口,提供优质的服务,而网格资源选择性配置方案,就是为解决现今网格中资源的不合理利用所提出的。首先,本文针对服务网格中资源的安全共享问题,提出了在复合条件下认证服务的资源共享方案,通过消息认证、签名方案和访问控制等方法保证在服务网格环境下资源共享方和资源申请方的个人信息和共享资源安全。其次,本文为解决服务网格中资源的不合理利用,传输过程中瓶颈造成的封包被动式丢弃管理等问题,通过研究在有限容量条件下多元受限任务的等待,提出了网格资源选择性配置方案以及对应的封包主动式管理GRS,通过建立数学模型,验证了算法的稳定性和可靠性,并对模型进行了仿真计算,验证了模型的可行性。在仿真实验过程中,与以往的被动式管理进行了对比分析,初步证明了方案的实际价值,论文最后对所作的工作进行总结,并指出有待进一步开展的工作。本文基于对服务网格中资源的安全共享和网格中资源的不合理利用等问题进行了研究,通过算法分析和仿真实验初步证明了该方案具有一定应用价值。笔者认为,随着网格技术和信息通信安全技术不断发展,这里提出的网格资源选择性配置策略和在复合条件下认证服务的资源共享方案将不断拓宽网格技术的商业化发展道路,具有一定的探索和创新精神。更多还原

【Abstract】 Nowadays, with increasingly sophisticated Internet technology and the third generation of the Internet suggested that the idea and practice of grid computing is no longer far away.The core of grid computing is resource coordination which focus on off-site heterogeneous resources controll by the non-concentrated.Through the Common Development Agreement and interfaces, it want to provide high quality service, while the selectivity of grid resource allocation solution is to solve the current irrational utilization in grid resources.First of all, the article focus on the security sharing of grid resource, it proposed the conditions of resource-sharing program in the composite certification services, through the message authentication, signature programs and access control and other methods to ensure that resource sharing and resource side applicant’s personal information and sharing of resource security under the service grid environment.Secondly, the article is to address the irrational use of Service Grid resources and the process of discarding packets passive management issues caused by transmission bottlenecks.Through researching the waiting under the conditions of a limited capacity-constrained multi-task, the article apply the selective grid resource allocation programs and the corresponding packet active management---GRS.Establishing the mathematical models,it verifies the stability and reliability of the algorithm.And it verifies the model’s feasibility simulation count. In the simulation process, with the previous passive management of the comparative analysis,it proves the real value of the program.Finally, the article sums up the work and notes that it needs to be further work in progress.Based on resource sharing and grid security of the irrational use of resources and other issues with a analysis of algorithms and simulation in the service grid. This article preliminary prove that the program has a certain value. I believe that, with the development of technology and information communication security technology, it presented for Grid Resource selective allocation strategies and resource-sharing program of certification services in the composite conditions will continue to broaden the commercialization of grid technology development.Thus it have a certain degree of exploration and innovation.更多还原
