The large scale networking activity provides leading edge network infrastructure for the high performance computational research activities and funds the gigabit and advanced networking research activities that include gigabit testbed activities and R&D pilot projects such as HiPPI, ATM, National Storage Lab, and On-line Electronic Telescope. It also includes R&D for packetized video and voice, next-generation IP deployment. The network infrastructure, ESnet, is an integral part of the National Information Infrastructure (NII) and the global internet supporting basic research. It provides worldwide access to Energy Research facilities, including: Advanced Light Sources, Neutron Sources, Particle Accelerators, Fusion Reactors, Spectrometers, High Performance Computing Resource Providers (HPCRP), Genome Centers, Data banks, and other leading-edge science instruments and facilities. Planned upgrades will facilitate remote experimentation and `national collaboratory` access to these facilities.
The ESnet project, using laboratory-industry partnerships, provides advanced services through the early acquisition and testing of commercially-supplied communications and network services. Funding covers acquisition of services and advanced network capabilities and integration of these with other services, primary rate ISDN for video, video multiport/services, hardware to expand network capabilities (routers, international links), personnel to develop tools for network use (e.g., communication, authentication, privacy protocols), advanced network information services, and maintenance. Funding may be provided for research and development on ATM issues with regard to High Performance Parallel Interface (HiPPI), standards implementation, interfaces, and LAN to WAN ATM interoperability. Funding may also be used to investigate the network resource reservation and management for isochronous traffic. With additional funding work is needed in identifying the real issues with inter-network peering and routing. Research on routing and addressing (e. g., end system identifiers, network versus geographical addressing, automatic host configuration, multi-level peering, etc.) for the growth of the Internet on a multi-protocol dimension must be conducted. |

Completed ESnet upgrade of eight sites to 45 Mbs fast packet services, the first Internet implementation of Asynchronous Transfer Mode (ATM) service.
Upgraded links to KEK, Japan (512Kbs) added an additional link to Garching, Germany (128Kbs), upgraded the Italy link to 768Kbs, installed data compressors on the Italy link, and successfully transitioned to the Network Access Point (NAP) architecture once NSFNET went away. Added additional video systems interoperability within ESnet, including production quality video and voice capabilities. Implemented massively parallel computer in the production environment. Delivered 576,000 Computer Resource Units (CRUs) to ER Programs. Supplied an additional 3 Terabytes of archival storage to ER programs. The Special Parallel Processing Program was expanded to 70,000 Computer Resource Units by 4Q95. SPP workshops were held for winning proposals. Brought the NSL technology-based archival storage system into limited production use. Brought up the Portable Batch System (PBS) to provide a uniform batch environment across all major platforms. |
Integration of ATM into the infrastructure was successful. Ten ATM ports are in production mode with speeds ranging from 4 to 155 Mbps. Additional sites have been integrated using frame relay-to-ATM connections or N times T1 connections where cost effective. Two ports are active at OC3c ATM service. Implemented a successful Internet Transition Strategy. Statistics show ESnet to be reliable and consistent and customer service remains high. Support was provided for Defense Programs activities by supporting unclassified and end-to-end encrypted data.
A transatlantic ATM pilot project was initiated to provide 5 to 10 Mbps ATM links to overseas collaborators in Europe. Initiated the standards process for HiPPI-6400, the gigabit speed system are network protocol successor of HiPPI. Developed Class Based Queuing (CBQ) IP gateways that control congestion as well as allow link sharing. Development of Random Early Detection (RED) gateways for congestion control and resource management on IP networks. Demonstrated successful remote control of a robot from a CAVE over high speed networks. Enhanced audio/video (e.g.,. VIC, VAT) collaborative tools and released reference implementations. Demonstrated a geographically distributed joint site immersive environment (CAVEs) using an OC-3 ATM network. Developed an initial design for a heterogeneous secure software distribution system. Initial development of advanced IP network analysis tools and techniques. Development of Real time protocol (RTP) and Multicast (Mtrace) tools. Initiated a set or ER-DP security workshops with the goal of identifying common security R&D as well as operational challenges. Developed a Pentium PC based ATM long link error simulator. Finalized the Real Time Protocol standard and reference implementation. Successful management and deployment of IWAY for SC '95. |
Maintain existing sites and upgrade ESnet bandwidth services, subject to budget constraints, to support Advanced Computational Testing and Simulation applications.
Provide increased connectivity and bandwidth to Europe and Japan. Connect the supercomputers at Sandia National Laboratory and Oak Ridge National Laboratory via a native ATM circuit. Deploy RED and CBQ in operational networks. Make available to others the PC based ATM simulator. Further develop high speed advanced interagency and internetwork peering and interconnection points. Prototype the Secure Software distribution system. Design and prototype a HiPPI-6400 switch and tester, as well as advance the standard. Continue the development and deployment of network traffic analysis and measuring tools. Develop a strategy, protocols, and tools that address congestion caused by WWW traffic (e.g., reliable multicast). |
