Collaborative Research: FRP: QoS-Assured Service Composition and Execution

网络中心软件和系统中心提案#1128344提案#1128270该提案寻求为北得克萨斯大学和德克萨斯大学的网络中心软件和系统中心站点提供资金。达拉斯。基础研究的资金申请由NSF批准的请愿书授权，NSF 10-601。征集邀请研究所/大学合作研究中心提交支持行业定义的基础研究的建议。软件开发越来越多地通过基于Web的服务提供的面向服务的体系结构(SOA)来实现，服务质量(Qos)是一个重要的问题，但在Qos范型中存在重大差距。建议的工作着眼于组合方法，其中在单个Web组件级别上已知Qos属性，并使用该属性来确定总体的全局Qos理解。提出的工作旨在建立一个全面的框架，用于保证服务质量的服务组合和执行，使用AQOS可重构服务范例、组合安全性和可靠性分析以及三阶段组合算法，以快速得到满足QOA要求的候选组合。拟议工作的结果可能会对软件开发和应用程序以及SOA社区产生重大影响。这项工作得到了行业咨询委员会以及该中心个别行业成员的支持。这一努力有可能通过进一步开发和应用所开发的服务质量框架来扩展中心？S的产品组合。PI计划根据工作开发以网络为中心的运营行业联盟(NCOIC)模式，并将这些模式发布给公众访问。该中心将让研究生参与这项工作。

Netcentric Software and Systems CenterProposal #1128344Proposal #1128270This proposal seeks funding for the Netcentric Software and Systems Center sites at the University of North Texas and the University of Texas ? Dallas. Funding Requests for Fundamental Research are authorized by an NSF approved solicitation, NSF 10-601. The solicitation invites I/UCRCs to submit proposals for support of industry-defined fundamental research. Software development is increasingly achieved via Service Oriented Architectures (SOAs) served through web-based services, Quality of Service (QoS) is an important issue yet major gaps exist in the QoS paradigm. The proposed work looks at the composition approach where QoS properties are known at the individual web component level and used to determine an overall global QoS understanding. The proposed work seeks to establish a comprehensive framework for QoS-assured service composition and execution using a A QoS-reconfigurable service paradigm, compositional security and reliability analysis recently developed by the group, and a three phase composition algorithm to rapidly arrive at candidate compositions that meet QoA requirements. The outcomes of the proposed work have the potential for significant impact in the area of software development and application and the SOA community. The work is supported by the Industry Advisory Board as well as individual industry members of the center. The effort has the potential to extend the center?s portfolio through further development and application of the QoS framework developed. The PI plans to develop Network Centric Operations Industry Consortium (NCOIC) patterns from the work and post these for public access. The center will involve graduate students in the work.
