            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.

            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.

            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.
