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.

ESCC X.500/X.400 Task Force [Page 4]
RFC 1330 X.500 and X.400 Plans for ESnet May 1992
1. Introduction
1.1. Abstract and Introduction
This document recommends an initial approach for the Phase I
deployment of OSI Directory Services (X.500) and OSI Message Handling
Services (X.400) within the ESnet community. It is anticipated that
directly connected ESnet backbone sites will participate and follow
the suggestions set forth in this document.
Section 7 of the "ESnet Program Plan" (DOE/OER-0486T, dated March
1991) cites the need for further research and investigation in the
areas of electronic mail and directory services. The ESCC
X.500/X.400 Task Force was created to address this need.
Additionally, the task force is addressing the issues of a
coordinated, interoperable deployment of OSI Directory Services and
OSI Message Handling within the entire ESnet community. Since only a
small subset of this community is actively pursuing these avenues,
considerable effort must be made to establish the necessary "base" to
build upon. If directly connected ESnet sites participate in these
services, a consistent transition path will be ensured and the
services provided will be mutually valuable and useful.
X.500 and X.400 are continuously evolving standards, and are
typically updated every four years. U.S. GOSIP (Government OSI
Profile) Requirements are updated to define additional functionality
as needed by the U.S. Federal Government, usually every two years.
As the X.500 and X.400 standards evolve and U.S. GOSIP Requirements
are extended, consideration must be given as to the effect this may
have on these existing services in the ESnet community. At these
cross-roads, or when a sizeable increase in service functionality is
desired, another "phase of deployment" may be in order. In this
sense, there isn't a specific "final phase" goal, but rather several
new releases (updates) to the level of existing services.
1.2. Structure of this Document
X.500 is presented first. The issues of DSA (Directory Service
Agent) deployment, DSA registration, naming schema, involvement in
the PSI White Pages Pilot Project, recommended object classes,
recommended attribute types, information security, search
optimization, user friendly naming and update frequency are
addressed.
In the area of X.400, issues relating to MTA (Message Transfer Agent)
deployment, ESnet X.400 well-known entry points, ESnet backbone site
X.400 well-known entry points, MTA registration, naming hierarchy,
