Overview

   The Energy Sciences Network (ESnet) is a nation-wide computer data
   communications network managed and funded by the United States
   Department of Energy, Office of Energy Research (U.S. DOE/OER), for
   the purpose of supporting multiple program, open scientific research.
   ESnet is intended to facilitate remote access to major Energy
   Research (ER) scientific facilities, provide needed information
   dissemination among scientific collaborators throughout all ER
   programs, and provide widespread access to existing ER supercomputer
   facilities.

   Coordination of ER-wide network-related technical activities over the
   ESnet backbone is achieved through the ESnet Site Coordinating
   Committee (ESCC). This committee is comprised of one technical
   contact person from each backbone site, as well as some members of
   the ESnet management and networking staff.  As the need for new
   levels of ESnet services arise, the ESCC typically creates task
   forces to investigate and research issues relating to these new
   services.  Each task force usually results in a whitepaper which
   makes recommendations to the ESnet community on how these services
   should be deployed to meet the mission of DOE/OER.

   This RFC is a near verbatim copy of the whitepaper produced by the
   ESnet Site Coordinating Committee's X.500/X.400 Task Force.
