Today's enterprise computing environments resemble the mythological chimaera: they are comprised of heterogeneous devices, ranging from PDAs to servers, which individually presents distinct, fragmented views of available data and services. To exacerbate the problem, devices are often managed by individuals with different interests and expertise. Thus, the parts are not even coordinated by a single brain! Unsurprisingly, these monsters are hard to use and maintain.This project is exploring two ingredients for the taming of these monsters: a peer-to-peer (P2P) file system and a decentralized coordination mechanism. The file system serves to unify the fragmented data views of devices into a global namespace, providing device-independent name and content addressing. Underneath the global view, the file system continually monitors device characteristics and user behaviors, and automatically adapts the replication and placement of data to achieve specified availability and durability targets.The coordination mechanism serves to govern the interactions between components within a decentralized system according to explicitly specified policies. Critically, this mechanism is based on an intrinsically decentralized system called Law Governed Interactions (LGI). This work explores the applicability of LGI to the above P2P file system and the experimental use of the resulting integrated system in the computing infrastructure of the Rutgers Computer Science Department.The expected outcome of the project is a demonstration of how P2P technologies can be used to build powerful and flexible, yet low-futz enterprise computing systems. The project will also produce two prototype building blocks that can be used for future investigations of decentralized systems.

当今的企业计算环境类似于神话中的嵌合体：它们由异构设备组成，从 PDA 到服务器，这些设备单独呈现可用数据和服务的不同的、碎片化的视图。 更糟糕的是，设备通常由具有不同兴趣和专业知识的个人管理。 因此，这些部分甚至不是由一个大脑协调的！毫不奇怪，这些怪物很难使用和维护。该项目正在探索驯服这些怪物的两个要素：点对点（P2P）文件系统和去中心化协调机制。 文件系统用于将设备的碎片数据视图统一到全局命名空间中，提供与设备无关的名称和内容寻址。 在全局视图下，文件系统持续监控设备特征和用户行为，并自动调整数据的复制和放置，以实现指定的可用性和持久性目标。协调机制用于根据明确指定的策略来管理去中心化系统内组件之间的交互。 至关重要的是，该机制基于本质上去中心化的系统，称为法律治理交互（LGI）。 这项工作探讨了 LGI 对上述 P2P 文件系统的适用性，以及由此产生的集成系统在罗格斯大学计算机科学系的计算基础设施中的实验使用。该项目的预期成果是演示如何使用 P2P 技术来构建强大、灵活、但低复杂度的企业计算系统。 该项目还将生产两个原型构建块，可用于未来的去中心化系统研究。
