Panel Review of Long-Haul Networking in Distributed Simulation

摘要

This report documents a review of the technical approach used to support long-hand, networked data communications in DARPA's Advanced Distributed Simulation Technology (ADST) Program. The review was conducted 1-2 March 1990 by an independent panel of five scientists whose comments are presented and summarized. The panel concluded that: (1) the current technical approach to long-haul data communication in ADST is sound, given current system requirements and resources; (2) the existing architecture and protocols will support a one order of magnitude increase in traffic over the next five years, assuming the current pace of improvements in computation continues and is reflected in system improvements; (3) the ability of the current approach to support a two order of magnitude increase in traffic over the next 10 years is much less certain; (4) the system has been appropriately designed to support migration to standardized architectures and protocols; (5) the system should incorporate standardized approaches where they satisfy the levels of performance needed, but performance should receive preference over standardization where they do not; (6) a comprehensive assessment of system requirements for long-haul data communications requirements in the network is needed and should be undertaken promptly; (7) general purpose mechanisms for network management and security should be incorporated in the system; (8) data collection and analysis of network traffic and requirements should be instituted as a routine component of system operations to monitor performance and to guide system modifications and growth.
