ALSM represents a major new stage in a research program in Logistical Computing and Internetworking, (LoCI), for distributed state management. The IP model is too limited for distributed computing because it does not include the possibility of managing application state between end systems (i.e. at intermediate nodes). The unique contribution of the LoCI approach is that it not only models this possibility, it does so without sacrificing the scalability essential to networking.While not viewing the IP model as sufficient for distributed systems, the project's strategy is to reapply the end-to-end design principles that underlie that model to storage and processor resources. The first target was storage. Following the end-to-end paradigm, the PIs created the Internet Backplane Protocol (IBP), which is a primitive mechanism for managing distributed storage. With IBP-based intermediate nodes, called depots, the network itself can be infused with storage resources that can be shared, scaled up, and exposed for external scheduling, much like IP service is. A testbed provisioned with more than 22TB of storage, spread among 250 depots in 20 countries has been deployed, and a variety of application groups are currently using the testbed to explore the technology.Following the LoCI design philosophy, ALSM.s guiding hypothesis is this: If, by adhering to end-to-end principles, a generic, best effort computing service can be integrated into ascalable logistical network, then a programmable network resource fabric can be created that is capable of providing the kind of active state management that grid applications require.The work will encompass the following main activities:o Design Active Depots and ALSM middleware: will optimize active depot architecture to efficiently support data transformation; middleware will be created to map a high level network view onto the weak semantics of IBP and the NFU, using sophisticated end-to-end techniques to generate reliability, performance, etc.o Enable GridSolve-L application environment: NetSolve will be adapted to use ALSM middleware so that NetSolve applications can issue logistical directives to exploit data locality patterns and offload state processing to active depots in the ALSM infrastructure. The result of this integration is GridSolve-L.o Validate ALSM in a grid visualization application: We will investigate the use of ALSM to implement a remote visualization pipeline, using a real-world medical imaging application under GridSolve-L; operations will separate as appropriate onto active depots for state management and GridSolve-L for major computation.

ALSM代表了一个重要的新阶段，在一个研究计划，在Logistics计算和互联网，（LoCI），分布式状态管理。 IP模型对于分布式计算来说太有限了，因为它不包括在端系统之间（即在中间节点）管理应用程序状态的可能性。LoCI方法的独特之处在于它不仅模拟了这种可能性，而且没有牺牲网络所必需的可扩展性。虽然不认为IP模型足以满足分布式系统，但该项目的策略是将该模型所依据的端到端设计原则重新应用于存储和处理器资源。第一个目标是存储。 遵循端到端的范例，PI创建了Internet背板协议（IBP），这是一种用于管理分布式存储的原始机制。使用基于IBP的中间节点（称为仓库），网络本身可以注入存储资源，这些资源可以共享，扩展和暴露以供外部调度，就像IP服务一样。ALSM已经部署了一个测试平台，其存储容量超过22 TB，分布在20个国家的250个仓库中，目前各种应用程序组正在使用该测试平台探索该技术。根据LoCI设计理念，ALSM的指导假设是：如果，通过坚持端到端原则，一个通用的，最大努力的计算服务可以集成到一个可扩展的物流网络中，o设计主动仓库和ALSM中间件：优化主动仓库的体系结构，以有效地支持数据转换;中间件将被创建来将高级网络视图映射到IBP和NFU的弱语义上，使用复杂的端到端技术来生成可靠性、性能等。o启用GridSolve-L应用环境：NetSolve将适应于使用ALSM中间件，以便NetSolve应用程序可以发出物流指令，以利用数据本地化模式并将状态处理卸载到ALSM基础设施中的活动仓库。 这种集成的结果是GridSolve-L.o ALSM在网格可视化应用程序中：我们将研究使用ALSM来实现远程可视化管道，使用GridSolve-L下的真实世界医学成像应用程序;操作将酌情分离到用于状态管理的活动仓库和用于主要计算的GridSolve-L。
