In many organizations, users of desktop personal computers and workstations depend on a network for shared access to files and other resources. Recent improvements in hardware technology have made portable computers the fastest growing segment in personal computing. However, standard system software has changed little in response to the new machines. Network access and stand-alone usage are supported, but there is no assistance for networked portable machines when they are disconnected. This deficiency significantly limits the productivity enhancement achievable with portable machines. Research techniques suggest that a much higher level of disconnected service is possible. This award supports development of new concepts and techniques for supporting network users when their systems are disconnected from the network. Disconnection must be treated as a normal, desirable mode of operation rather than an error condition. For days at a time, disconnected machines should be able to deliver most of the rich functionality associated with the network environment. This includes access to (pseudo) shared network files and other resources. Providing this rich collaborative work capability around the clock, irrespective of geographic location, could alter the way individuals approach their work and significantly increase productivity. The research will develop and validate the underlying technology for a system software product for networked portable computers.

在许多组织中，台式个人计算机和工作站的用户依赖网络共享对文件和其他资源的访问。最近硬件技术的改进使便携式计算机成为个人计算机中增长最快的部分。然而，标准系统软件对新机器的响应几乎没有变化。支持网络访问和独立使用，但是当联网的便携式机器断开连接时，没有任何帮助。这一缺陷极大地限制了便携式机器可实现的生产率提高。研究技术表明，更高级别的断开连接服务是可能的。该奖项支持新概念和技术的开发，用于在系统与网络断开连接时支持网络用户。断开必须被视为正常的、理想的操作模式，而不是错误情况。在一段时间内，断开连接的机器应该能够提供与网络环境相关的大部分丰富功能。这包括对（伪）共享网络文件和其他资源的访问。全天候提供这种丰富的协作工作能力，无论地理位置如何，都可以改变个人处理工作的方式，并显著提高生产力。该研究将开发并验证用于联网便携式计算机的系统软件产品的基础技术。
