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

国家科学基金会建议：0820222/0820170标题：重组服务--为不断进化的系统重塑网络PI：Richard N.Taylor和Nenad Medvidov许多现实世界系统的广泛特征掩盖了经典系统和软件工程的假设：没有单一的至高无上的权威，变革由许多独立的组织管理，许多系统服务于许多主人，进化是独立的和不协调的。在普及网络基础设施的规模和覆盖范围方面的持续改进，以及各种可通过网络访问的资源的迅速发展，将在未来的系统系统中发挥关键作用。对于这个未来，这个项目提供了对服务抽象的彻底反思，它集成了现代网络结构、计算作为网络交换的基本单元，以及网络范围的系统意识，以提供服务组合、重用、自治、上下文无关交互和监控为首要影响的重组互联网规模的服务。该项目追求一套解决挑战的体系结构原则，然后开发符合这些原则的基础设施，用于系统系统的实现、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计算驱动和自主的体系结构。我们的成果将提供给开放源码社区和外部合作组织，这是一种具有改变网络潜力的技术转移。

NSF Proposals: 0820222/0820170Title: Recombinant Services -- Recasting the Web for Continuously Evolving SystemsPIs: Richard N. Taylor and Nenad MedvidovicThe 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.
