That group also reported the following: "On the scientific level, we anticipate system resource conf~icts arising that will demand resolution within the confines of the data and information system. Multidisciplinary researchers and research teams wild have needs for particular observational sequences, while disciplinary researchers may weld have requirements for entirely different measurements.

Late in this decade the Rubble Space Telecope wild be launched. The Hubble Telescope plus the Space Telescope Science Institute wild constitute an observatory like those on earth, only with the telescope above the atmosphere.

Most data formats now are mission-specific, but NASA wants a transition to generic structures and processes, since the goals are to maintain the data sets and relevant information in a consistent form and to enable users to obtain data with no manual intervention. OSIDS and GSFC have represented NASA on the Consultative Committee on Space Data Systems (CCSDS)

TP-4 and the Internetwork Protocol were approved by the "ISO" as Draft International Standards in 1983 and 1984, respectively. Since commercial vendors normally consider Draft International Standards to be ready for implementation, there has been some expectation that commercial equipment manufacturers will employ the "ISO" standard protocols.

The purpose of COS is: "to provide an international vehicle for accelerating the introduction of interoperable, multivendor products and services operating under agreed-to OSI, Itegrated Services Digital Network (ISDN) and related international standards to assure acceptance of an open network architecture in world markets." COS proposes to achieve its objectives through establishment of conformance and interoperability test programs to verify member-companies' product compliance with the "ISO" OSI standards and by identifying areas "Continued from 0.29]

The Committee understands that OSSA is considering use of the NSFnet for data as weld as electronic mail distribution to researchers. Within the time-frame currently being assumed for the NASA environment, there is a reasonable expectation that the evolving NSFNet will be able to support the data rates implied by the l- and lO-Mbps rates discussed above.

OSSA will be provided several design solutions, reflecting both the technological state of the art and the creativity of the competing contractors, enabling it to select system and subsystem design configurations that wild do the job at the best price. This would enable OSSA to request and evaluate proposals that include provisions for a migration path to TP-4.

The adoption of common standards among the research networks of major agencies such as NASA allows users to have maximum flexibility with respect to access to their data, use of common campus networks and facilities, use of alternative access routes that provide flexibility, and use of nationally-supp~ied communications facilities. We believe OSSA is taking the proper approach to this issue.
