Energy Services Network (ESnet) _A_d_d_r_e_s_s: NERSC L-561 Lawrence Livermore Labs Livermore, Ca. 94550 _E_m_a_i_l: info@es.net _P_h_o_n_e: 1-800-33-ESNET _D_e_s_c_r_i_p_t_i_o_n ESnet is a computer data communications network managed and funded by the Department of Energy Office of Energy Research (DOE/OER) for the purpose of supporting open scientific research in multiple programs. ESnet is intended to facili- tate access to resources at ER scientific facilities, to provide for information dissemination among scientific col- laborators throughout all ER programs, and to provide widespread access to existing supercomputer facilities via remote login, electronic mail, file transfer, and related utilities. ESnet is installed and operated by the National Energy Supercomputer Center (NERSC), formerly known as the National Magnetic Fusion Energy Computer Center (NMFECC), which is located at Lawrence Livermore National Laboratory (LLNL) in California. ESnet policy is guided by the ESnet Steering Committee, appointed by the DOE Office of Scientific Comput- ing, with representatives from each of the Energy Research Programs. The ESnet program plan, prepared by this commit- tee, is available from the National Technical Information Service as report DOE/ER-0341 (June 1987). The ESnet backbone consists of largely of T1 links (1.544 megabit per second) interconnecting nineteen sites in the United States. Network access to Europe and Japan is also supplied in collaboration with foreign research facilities. _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide. April 26, 1990 NNSC Section 5.31, Page 1 ESnet will also provide backbone capabilties to the Magnetic Fusion Energy Network (MFEnet) and the High Energy Physics Network (HEPnet) communities. In terms of protocols, ESnet supports TCP/IP and Digital Equipment Corporation's DECnet. ESnet will support X.25 and the OSI protocols as they become available from vendors. _N_e_t_w_o_r_k _A_c_c_e_s_s: ESnet is not available for use by the general public, nor is it intended to compete with comparable commercial network services. ESnet is available for access by researchers, facilities, and groups participating in or collaborating with Office of Energy Research (OER)-sponsored activities. NERSC provides user services for ESnet. _M_i_s_c_e_l_l_a_n_e_o_u_s _I_n_f_o_r_m_a_t_i_o_n For more information contact: Jim Leighton, 415-422-4025, jfl@es.net, Network Manager Tony Hain, 415-422-4200, hain@eagle.es.net, Associate Net- work Manager Bob Aiken, 415-422-4474, aiken@es.net, Network Information and Services Group April 26, 1990 NNSC Section 5.31, Page 2
