This project continues previous research in network time- synchronization technology and proposes new algorithms adapted for use in high speed, wide area networks including supercomputers and superscalar workstations. The technology makes use of the Network Time Protocol (NTP) widely used now in the Internet, together with engineered modifications designed to improve accuracy in high speed networks, including SONET and ATM. The project also involves the design and construction of precision timekeeping devices that provide improved timekeeping accuracy which it is expected to improve to some tens of microseconds in modern RISC-based workstations. Finally, the project involves the conduct of experiments designed to evaluate the success of the research and assist technology transfer to computer manufacturers and network providers. The requested support will permit the assignment of professional management and staff resources to implement these programs so that the efforts of the regional and other midlevel network participants can be coordinated.

该项目继续在网络时间同步技术方面进行以前的研究，并提出了适用于高速，广泛网络（包括超级计算机和超大标准工作站）的新算法。 该技术利用了现在在Internet中广泛使用的网络时间协议（NTP），以及旨在提高包括SONET和ATM在内的高速网络的精确度的工程修改。 该项目还涉及精确计时设备的设计和构建，这些设备提供了提高的计时准确性，预计在现代RISC工作站中，它将改善一些微秒。 最后，该项目涉及旨在评估研究和协助技术转移到计算机制造商和网络提供商的成功的实验的进行。 要求的支持将允许专业管理和员工资源的分配来实施这些计划，以便可以协调区域和其他中级网络参与者的努力。
