Communication processors

A review is given of the use of small digital computers for the processing of data received over communication lines. A detailed discussion is presented of the hardware and software requirements of front-end processors, network processors, remote data concentrators, and message switching systems. Finally, the desirable features common to all communications processors are analyzed. Examples of actual applications are given, so that a realistic basis can be established for the determination of the features which should be included in the design of new communication processors.
