Distributed systems are becoming ever more important as they provide information support for basic infrastructures such as electrical and telephone service, and as a means for corporations to manage worldwide operettas. They are also becoming ubiquitous because many applications demand greater computational power and require distributed resources. The net impact is that a vast amount of data needs to be shared across a broad array of users.The proposal plans to investigate the long-term issues of mobility and efficiency in the design of scalable middleware for distributed systems. The effort will include the implementation of a distributed middleware for mobile environments. Specific research themes to be pursued are:- formalization and implementation of consistency requirements for middleware- algorithms for data placement and replication- protocols for support of conflict resolution and the support of mobility, and- incorporation of stream data in a computational framework.The results of these investigations will be the development of an experimental prototype that uses the researched algorithms and protocols. In order to experiment with the prototype, a number of applications will be implemented in a campus environment. The goal of the research is to help guide long-term development of middleware at large scale.

分布式系统变得越来越重要，因为它们为电气和电话服务等基本基础架构提供信息支持，并为公司管理全球歌剧的一种手段提供了支持。 它们也变得无处不在，因为许多应用程序需要更大的计算能力并需要分布式资源。 净影响是，需要在各种各样的用户中共享大量数据。提案计划研究了分布式系统的可扩展中间件设计中的移动性和效率的长期问题。 这项工作将包括用于移动环境的分布式中间件。 要追求的具体研究主题是： - 中间件算法的一致性要求 - 用于支持冲突解决和支持移动性的数据放置和复制协议的一致性要求，并将流数据纳入计算框架中。这些研究的结果将是使用研究的实验类型的开发研究的原型，该原型利用了研究后的Algoriths和Stonstects和协议。 为了实验原型，将在校园环境中实施许多应用程序。 该研究的目的是帮助指导大规模的中间件的长期发展。
