Advances in Computer Network Timekeeping

该项目延续了前人对网络时间同步技术的研究，并提出了适用于包括超级计算机和超标量工作站在内的高速广域网络的新算法。这项技术利用了目前在互联网上广泛使用的网络时间协议(NTP)，以及旨在提高包括SONET和ATM在内的高速网络中的准确性的工程修改。该项目还涉及设计和建造精确的计时装置，以提高计时精度，预计在基于RISC的现代工作站中，计时精度将提高到几十微秒。最后，该项目涉及进行旨在评估研究成功的实验，并协助向计算机制造商和网络供应商转让技术。所要求的支助将允许分配专业管理和工作人员资源来执行这些方案，以便能够协调区域和其他中级网络参与者的努力。

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.
