The proposal describes a DHT-based approach to constructing a scalable and distributed information management system that aggregates information about large scale networked systems. Such a system is envisioned to be a key enabler of large-scale distributed applications through monitoring, querying and reacting to changes in the state of the distributed system(s). A prototype will be developed and experiments in collaboration with TACC are expected to enhance grid infrastructure in the near-term with usable technology to improve data replication, grid information systems, and distributed network monitoring. The proposal addresses new scalability, flexibility, autonomy, and robustness concerns raised by the tight integration of the aggregation tree abstraction with the internal DHT structure. By providing the equivalent of a distributed systems control backplane, middleware infrastructure should be greatly enhanced and simplify distributed application development and use.

该提案描述了一种基于分布式哈希表的方法来构建一个可扩展的分布式信息管理系统，该系统聚集了关于大规模联网系统的信息。这样的系统被设想为通过监视、查询和响应分布式系统状态的变化而成为大规模分布式应用的关键使能器(S)。将开发一个原型，并与TACC合作进行试验，预计将在短期内利用可用的技术加强网格基础设施，以改进数据复制、网格信息系统和分布式网络监控。该提议解决了聚合树抽象与内部分布式哈希表结构的紧密集成所引起的新的可扩展性、灵活性、自主性和健壮性问题。通过提供相当于分布式系统控制底板的功能，中间件基础设施应该得到极大的增强，并简化分布式应用程序的开发和使用。
