Internetting and packet satellite program

As a means of utilizing valuable communications resources more efficiently, The Department of Defense Advanced Research Projects AGency has sponsored a program of research and development in the area of packet-switched data networks. In addition to more efficient utilization, packet switching systems with autonomous distributed control can be made robust and survivable. In support of this program, BBN has conducted research and development in the areas of Internetting and the efficient use of broadcast satellite channels by packet-switched networks. Specific work performed under this contract involved the development of Internet gateways to interconnect many different types of dissimilar packet-switched networks, Internet protocols for data communication, and a Terminal Access Controller utilizing these protocols for remote network-access to time-shared computer systems. BBN also continued the development of the Atlantic Packet Satellite Network, (SATNET) providing Internet connectivity between sites in the U.S. and Europe using a shared 64kb/s INTELSAT satellite channel, and the domestic Wideband Packet Satellite Network, providing high bandwidth communication among ten sites within the continental U.S.
