TLDR
The packet switch used in the DARPA Wideband Packet Satellite Network and the Butterfly#8482; Multiprocessor on which it is based is described.Abstract:
Multiprocessor computer systems have proven effective as high performance switching nodes in packet switched data communications networks. They are well suited to performing the required queuing, routing, and scheduling tasks, and can scale upward to provide higher system throughput when combined with software that exploits the parallelism provided by the hardware. This paper describes the packet switch used in the DARPA Wideband Packet Satellite Network and the Butterfly™ Multiprocessor on which it is based.read more

Audio and video transmission and receiving system
Paul Yurt,H. Lee Browne +1 more
TL;DR: In this paper, a system of distributing video and audio information employs digital signal processing to achieve high rates of data compression, and the compressed and encoded audio and video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

Active bridging
TL;DR: This paper describes the design, implementation, and performance of a new type of network element, an Active Bridge, which can be reprogrammed "on the fly", with loadable modules called switchlets, and relies on strong type checking in the Caml language for the loadable module infrastructure, and achieves respectable performance.

Experience with Speech Communication in Packet Networks
C. Weinstein,J. Forgie +1 more
TL;DR: Large-scale packet speech multiplexing experiments could not be carried out on ARPANET or SATNET where the network link capacities severely restrict the number of speech users that can be accommodated, but experiments are currently being carried out using a wide-band satellite-based packet system designed to accommodate a sufficient number of simultaneous users to support realistic experiments in efficient statisticalmultiplexing.
