Collaborative Research: Recombinant Services -- Recasting the Web for Continuously Evolving Systems

NSF提案：0820222/0820170标题：重组服务--为不断发展的系统重塑网络。许多现实世界系统的广泛特征与经典系统和软件工程的假设不符：没有单一的支配性权威，变化由许多独立的组织管理，许多系统为许多主人服务，进化是独立和不协调的。普及网络基础设施的规模和覆盖面的不断改进以及各种网络可访问资源的迅速发展将在未来的系统中发挥关键作用。关于这个未来，该项目提供了一个彻底的重新思考服务抽象，集成现代网络结构，计算作为网络交换的基本单元，和网络范围的系统意识，提供重组互联网规模的服务，服务组合，重用，自治，上下文无关的交互和监控是一阶效应。该项目追求一套架构原则，解决这些挑战，然后开发与这些原则相一致的基础设施，用于系统的系统的实施，部署和操作。将重组服务具体化的工程方法-CREST-将重塑Web，从一个主要由数据驱动和反应的体系结构转变为一个由计算驱动和自主的体系结构。我们的成果将提供给开源社区和外部合作组织，这是一项具有改造Web潜力的技术转让。

NSF Proposals: 0820222/0820170 Title: Recombinant Services -- Recasting the Web for Continuously Evolving Systems PIs: Richard N. Taylor and Nenad Medvidovic The broad features of many real-world systems belie the assumptions of classical systems and software engineering: there is no single overarching authority, change is managed by many independent organizations, the many systems serve many masters, and evolution is independent and uncoordinated. Ongoing improvements in the scale and reach of pervasive network infrastructure and the brisk development of diverse Web-accessible resources will play pivotal roles in future systems of systems. Apropos of this future, this project offers a radical rethinking of service abstraction that integrates modern network structures, computation as a fundamental unit of network exchange, and network-wide system awareness to deliver recombinant Internet-scale services for which service composition, reuse, autonomy, context-free interaction, and monitoring are first-order effects. This project pursues a set of architectural principles addressing the challenges, then developing infrastructure consistent with those principles, for the implementation, deployment, and operation of systems of systems. The engineering methods reifying recombinant services---CREST---will refashion the Web, from an architecture that is predominantly data-driven and reactive to one that is computation-driven and autonomic. Our results will be given to the open source community and external collaborating organizations, a technology transfer with the potential of transforming the Web.
