DescriptionFrom University Video Communications' catalog:
"Sandy Fraser describes the evolution of Asynchronous Time Division Multiplexing (ATDM) and ATM technologies. Using three experimental networks, he shows how basic concepts emerged and were realized, and how each network helped illuminate the special properties of ATM. Spider, the first network, concentrated traffic into one port of a space-division virtual circuit switch in software. The second project switched data entirely in hardware. Datakit, the third network, provided lessons in error detection, flow control and retransmission, managing traffic, and fairness in a heavily loaded network combined with assurances about throughput, delay, and congestion control."
