The international BITNET network began in the spring of 1981 when Ira H. Fuchs and Greydon Freeman, of the City University of New York and Yale University, respectively, decided that IBM's Network Job Entry (NJE) communications protocol made computer-based communication practical between their universities. BITNET, the "Because It's Time" network, began in the US as these two universities began using a leased telephone circuit for communications between accounts on their mainframe computers. BITNET both reached across the US to California and was joined by its European counterpart EARN (European Academic and Research Network) in 1982. Other cooperating international networks joined, in the ensuing years, to make BITNET a worldwide network.
At its peak in 1991-2, this network connected some 1,400 organizations in 49 countries,
for the electronic non-commercial exchange of information in support of research and education. In this truly cooperative network, each participating organization contributed communications lines, intermediate storage, and the computer processing necessary to make its part of the network function. It provides electronic mail and, thanks largely to the volunteer efforts of Eric Thomas, thousands of electronic mailing lists based on the LISTSERV software for managing such lists. It is also used for transfer of data and software files, and for rapid transmission of "interactive" messages and commands to software such as LISTSERV. It was, for several years the largest academic network in the world for computer-based communications, but by the 1992-1993 time frame, the number of academic organizations connected to the Internet outnumbered those participating in BITNET. The number of BITNET participants began to decrease in 1993.
BITNET's development in the US was facilitated by an IBM grant in July 1984 which provided initial funding for the establishment of centralized network support services. The BITNET Network Information Center, BITNIC, received its initial funding from this IBM grant but, since the grant's conclusion in 1987, has been funded entirely by membership dues from the participating organizations. The network has continued to rely heavily on the volunteer support of its participating colleges and universities for creative new ideas and software, and for essential operational support.
A BITNET Executive Committee, consisting of representatives from the major US BITNET nodes, was formed in 1984, to develop BITNET policies and to plan for its future. In 1987 the BITNET Executive Committee formed a nonprofit corporation whose members were the organizations participating in the BITNET network. In 1989, when BITNET merged with the Computer+Science Network, CSNET, it adopted the new corporate name, the Corporation for Research and Educational Networking, CREN. (The growth of the Internet overtook CSNET in 1991, and its services were discontinued.) CREN is governed by a Board of Trustees elected by its member organizations.
BITNET users share information via electronic mail to individuals and shared-interest groups; transfer documents, programs, and data; access to BITNET server machines and associated data services; and brief, nearly-interactive messages. Nearly 3,000 discussion groups on BITNET cover most topics of academic interest and may have from five participants to several thousand. Gateways allow the exchange of electronic mail between BITNET and the Internet, and also other networks.
BITNET is a "store-and-forward" network; information originating at a given BITNET-connected computer (node) is received by intermediate nodes and forwarded to its destination. Although BITNET uses IBM's NJE communications protocol, VAX/VMS systems actually constitute the majority of BITNET nodes; Unix and other systems are also supported, in addition to IBM systems running VM or MVS.
As BITNET participants migrate onto the Internet, CREN and many of the other organizations supporting BITNET throughout the world are turning their focus to supporting their members' use of the Internet and assisting in their members' migration. CREN's historic strategic mission has been to support low-cost access to worldwide electronic networking and its use for the benefit of the education and research communities. CREN’s mission has currently been augmented to support institutions of higher education by providing seminars, workshops, educational and training materials, and software tools which enable their information technology professionals to understand and exploit advances in technology; train faculty, students, and staff in strategic technology areas using distance education modules; and provide leadership in using distance education and collaboration technology. CREN has focused on the Internet and the world-wide-web as the platform for such services.
CREN believes that the people who are advocating and supporting the information technology infrastructures on member campuses should have the opportunity to directly experience advanced technology for the delivery of training and learning materials. CREN's "Virtual Seminars" provide just such an opportunity.
CREN has developed list-management software for use on low-cost Unix platforms, which is optimized to the Internet protocols and compliant with Internet standards. This software (ListProc) is available to CREN's members and also to non-members, to facilitate the development and use of electronic mailing lists.
As a Founding Organizational Member of the Internet Society, CREN will continue its support of the Internet Society and its participation in the Internet Engineering Task Force to develop standards, policies, and information useful to CREN members and the broader networking community.
CREN will continue to investigate and support other software and services which may facilitate the use of networking services for the benefit and improvement of research and education.
