CSR-DMSS, SM, Harmony: Efficient Integrated Resource/Trust Management in Large-Scale Distributed Systems

过去十年的技术进步为大规模分布式系统（LSDS）带来了一个充满希望的未来，在这种系统中，全球分散的分布式资源将被集体汇集并以合作的方式使用，以实现前所未有的千万亿次超级计算能力。无所不在的用户没有预先存在的信任关系，这对协作资源共享提出了挑战。这些事实要求解决资源管理（resMgt）和信任管理（trustMgt）问题，以确保成功部署LSDS。然而，这两个问题通常是单独解决的，尽管它们之间存在显著的相互依赖性：resMgt需要trustMgt为资源共享提供合作环境，反过来又促进trustMgt在提供各种资源时评估节点的多方面可信度。该提案旨在通过开发分布式软件架构来集成resMgt和trustMgt。拟议的项目建立在两个关键创新的基础上。(1)轻量级多资源管理。与大多数以前的多资源管理方法不同，这些方法依赖于多个基础设施并产生高开销，或者一个基础设施但导致瓶颈，而该项目涉及一个没有瓶颈的分层集成基础设施。(2)一体化的多方面信任管理。大多数以前的trustmanagement方法可能无法通过为节点分配单个信任值来提供资源选择的正确指导，而与之不同的是，该项目提供了跨多个资源的多方面信任评估。此外，它促进了trustMgt和resMgt之间的交互。

Advancements in technology over the past decade are leading to a promising future for large-scale distributed systems (LSDS), where globally-scattered distributed resources will be collectively pooled and used in a cooperative manner to achieve unprecedented petascale supercomputing capabilities. Ubiquitous users without preexisting trust relationships have posed a challenge of cooperative resource sharing. These facts necessitate that the issues of resource management (resMgt) and trust management (trustMgt) be addressed in order to ensure the successful deployment of LSDS. However, these two issues are typically addressed separately, despite the significant interdependencies between them: resMgt needs trustMgt to provide a cooperative environment for resource sharing, and in turn facilitates trustMgt to evaluate node multi-faceted trustworthiness in providing various resources. This proposal is aimed at integrating resMgt and trustMgt through the development of a distributed software architecture. The proposed project is built on two key innovations. (1) Lightweight multi-resource management. Unlike most previous multi-resource management approaches that depend on multiple infrastructures and incurring high overhead, or one infrastructure but causing bottlenecks, the project involves a single hierarchically integrated infrastructure without bottlenecks. (2) Integrated multi-faceted trust management. Unlike most previous trustMgt approaches that may not provide correct guidance for resource selection by assigning a node a single trust value for providing all resources, the project offers multi-faceted trust evaluation across multiple resources. Furthermore, it facilitates interaction between trustMgt and resMgt.
