Octoport: use of an SEL 32/75 and regional processing units as a minicomputer concentrator

Conference ·
OSTI ID:5724867
Lawrence Livermore Laboratory (LLL) is currently building a high-speed Data Communications System that will allow remote, user-operated minicomputer systems to share the resources of Octopus, the large, on-site computer network. The system will accommodate minicomputers from different manufacturers, operating at different speeds and under different protocols. An SEL 32/75 serves as a concentrator for four Regional Processing Units (RPU), each of which multiplexes 32 communication lines. Octoport provides 128 high-speed (9600 - 250 K Baud) serial lines to remote (up to two miles) users. This paper discusses the integration of the RPU into the Octoport system. 6 figures.
