A time division multiple access satellite communication architecture is disclosed to achieve a relatively simple control procedure for permitting multiple computers to establish peer coupled transmission paths for high speed transfer by dynamically allocating satellite communication facilities in a sequentially shared broadcast mode. Each sequentially established CPU-to-CPU logical link takes the form of a point-to-multipoint sub-network which incorporates a standard data link control protocol for the control of information transfer. The function of the primary station is sequentially passed from station to station within the network and as each station assumes primary control of its logical point-to-multipoint circuit, other stations conform to the secondary role for that logical link configuration.
