Abstract The deployment of broadband public packet networks requires integrating packet technology into the larger, predominantly circuit‐switched world. In this paper, we translate the need for circuit‐switched network compatibility into a class of packet transport capabilities referred to as circuit emulations. We first present our initial estimates of performance goals for emulating circuit‐switched connections in a broadband packet network. To show the feasibility of this new networking approach, we then describe a switch design capable of satisfying the stringent packet loss rate and delay requirements for emulating circuits at the DS1 rate and above. Finally, we demonstrate the ability to reconstruct continuous signals from emulated circuits using a simple time‐averaging clock recovery scheme based on a computer simulation model.
