Technical Committee on Computer Communications (TCCC)

TCCC History

The IEEE CS TCCC was founded in the mid 1970s upon the upcoming of LANs and communications between nodes. Ethernet and related approaches have seen a majority of support in terms of standards work from the TCCC.

TCCC 1978 THROUGH 1983

Records of TCCC activity during these years have yet to be located. However, an interview with Dr. Harvey Freeman yielded some insights. TCCC Chairs during this timeframe include:
  • Dr. Ken Thurber, TCCC Chair 1978 through 1979
  • Dr. Harvey Freeman, TCCC Chair 1980 through 1981
  • Dr. Rob Rosenthal, TCCC Chair 1982 through 1983
During Dr. Freeman’s tenure as TCCC Chair proved to be an exciting time in local area network (LAN) definition, standardization, and deployment. It was during these years that Marius Graube started the 802 committee. Dr. Freeman was approached to host these early 802 committee meetings as a TCCC subcommittee. He recalls the different industry sponsors pushing the 802 committee to standardize Ethernet over IBM’s Token Ring technology. Ethernet was developed at Xerox PARC between 1973 and 1974. In 1979 3Com was formed by Bob Metcalfe who convinced Digital Equipment Corporation (DEC), Intel, and Xerox to work together to promote Ethernet as a standard. Token Ring was a LAN technology mostly used by IBM. Ethernet was standardized as 802.3 in 1982; Token Ring was standardized as 802.5 in 1985.


As part of the LAN revolution, Dr. Freeman was approached to start a conference with a specific focus on LAN technology. InfoCom was started in 1982 in response to this request. It was a joint conference sponsored by the IEEE Computer Society (CS) and the IEEE Communications Society (ComSoc) until 2002 when it became solely sponsored by ComSoc.

TCCCs major flagship conference was, since the early days, the LCN (IEEE Conference on Local Area Networks), which was run in Minneapolis, Minnesota, U.S.A. until its 22nd appearance in 1997. The first LCN conference was held on September 16-17, 1976 in Minneapolis, Minnesota, sponsored by the University of Minnesota (UMN), University Computer Center with the cooperation of Network Systems, Inc. The two primary organizing committee members included Dr. Peter C. Patton and Dr. Abe Franck, UMN Computer Center.

At this first running the conference was entitled the “Conference on Experiments in New Approaches to Local Computer Networking”. The second running was October 13-14, 1977 when the name changed to the ‘Conference on “A Second Look at Local Computer Networking”’. The third running was October 23-24, 1978 when the conference name changed again to the “Third Conference on Local Computer Networks”. Since then the conference was simply called LCN. From the fourth LCN (1979) on, the conference was sponsored by the IEEE Computer Society Technical Committee on Computer Communications.
