Human Exploration and Development of Space Needs Space Wide Web: Incorporating Reusable Adaptive Technology 'Space Wide Web Supported by Adapters in Very Large Distributed Systems Configuration'

摘要

Human exploration and development of space will involve opening the space frontier through information technology, while expanding the human experience into the far reaches of space. At that point in time we assert that the current primitive World Wide Web (Web) will be replaced and dramatically expanded into an Interstellar Space Wide Web (SWW). Our approach to solving this problem is through the development of a novel configuration model and network-aware run-time environment called SWWACXML, for Space Wide Web Adapter Configuration extensible Markup Language. SWWACXML provides support for cross-layer architectural configuration at both the application level and the level of individual network connections. The language associated with this environment captures component interaction properties and network-level QoS constraints. Adapters will be generated automatically from SWWACXML specifications. These adapters are part of the SWWACXML runtime system. The runtime system includes facilities for automatic configuration and runtime reconfiguration, as well as efficient management of network connections and QoS options. This facilitates reuse because components are not tied to interactions or environments. We believe our approach is amenable to facilitate a style of dynamic reconfiguration, where clients can at runtime change server, communication or interaction protocol. We are modeling and designing the SWWACXML system in a distributed test-bed. We are modeling and designing performance analysis techniques to judge the success and efficiency of our approach.
