This proposal addresses the area of dependable grids through an approach that allows for degradation and failure scenarios of primary grid services in the presence of alternate services restricted to covering selected classes of failures. These services will be developed and specified under a custom notation permitting dependability characteristics to be defined and shared. The resulting survivable grid implementation will be prototyped on a foundation of the OGSA-based framework using existing grid resources at UVA and NCSA.The work promises to forge new ground in the research and development of survivable and dependable services in distributed systems, specifically the emerging web service-based grid environment. By adopting a framework and methodology, and in large part through the creation of a new language for specifying and sharing dependability requirements and characteristics among services (called DESL), the concept of feasible and dependable grid services may come to fruition in prototype form. Such an accomplishment will have immediate impact on a class of critical infrastructure applications. In addition to strong graduate level student involvement, the project includes significant support for undergraduates and direct involvement of UVA's Office of Minority Programs.

该提案通过一种方法解决了可靠电网领域的问题，该方法允许在存在仅限于覆盖选定故障类别的备用服务的情况下出现主电网服务的降级和故障场景。 这些服务将根据允许定义和共享可靠性特征的自定义符号来开发和指定。 由此产生的可生存网格实现将在基于 OGSA 的框架基础上使用 UVA 和 NCSA 的现有网格资源进行原型设计。这项工作有望在分布式系统中的可生存和可靠服务的研究和开发方面开辟新的领域，特别是新兴的基于 Web 服务的网格环境。 通过采用框架和方法，并且在很大程度上通过创建一种新的语言来指定和共享服务之间的可靠性需求和特征（称为DESL），可行且可靠的网格服务的概念可能会以原型形式实现。 这样的成就将对一类关键基础设施应用产生直接影响。 除了研究生级别学生的大力参与外，该项目还包括对本科生的大力支持以及弗吉尼亚大学少数民族项目办公室的直接参与。
