Lawrence Livermore National Laboratory (LLNL) has an existing LAN architecture which efficiently routes and services approximately 15,000 computers at the Livermore site, Site 300, and within the town of Livermore. Connections are provided by Ethernet, FDDI, and T1. Nodes, hubs, and services provide sufficient features to efficiently integrate more than 140 subsets and serve more than 350 buildings. The LAN includes a switched backbone, secure net encryption, and Internet capabilities.
Additionally, LLNL is taking aggressive action to define and develop very high bandwidth capabilities for meeting its future network needs. This action will support the Department of Energy’s (DOE’s) Accelerated Strategic Computing Initiative and promote further advancement by applying emerging communication and networking technologies.
To date, significant initiatives include participation in ANSI standards development and development of an Asynchronous Transfer Mode (ATM) network testbed and a Fibre Channel testbed. The ATM network testbed connects advanced LLNL facilities (including compressed video) with the National Transparent Optical Network (NTON), a 10-gigabit-per-second prototype network for high profile, high bandwidth emerging technologies and applications. LLNL is the lead integrator for the NTON and has led the network design, management, and application activities. The NTON consortium comprises key telecommunications organizations including NORTEL, Pacific Bell, Sprint, Rockwell, Hughes, Uniphase Telecommunications Products, University of California at San Diego, Columbia University, and Case Western Reserve University in addition to LLNL.
The NTON uses wavelength division multiplexing which provides significant capabilities for new bandwidth allocation. The NTON currently implements star topology and will incorporate full bi-directional ring topology upon completion of the fibre paths. The network will operate as an open testbed for demonstrating emerging technologies with high-capability, low-cost, format-transparent, wavelength-on-demand features
