Abstract : Recent advances in computer communications are discussed, including: (1) Computer traffic characteristics in the case of long holding time representing scientific applications, and in the case of short holding time representing the inquiry-response systems; (2) Telephone channel error characteristics of high speed voice band data transmission on the switched telecommunication network, and of the low speed channel at a rate of 300 bits/sec; (3) Optimal fixed message block size for communication systems using error detection and retransmission as error control (with random or burst error channel); (4) Statistical multiplexing (Asynchronous Time Division Multiplexing); (5) Loop systems; (6) Security in computer communications. New areas needing further investigation are included. (Author)
