Title: Packet-voice communication on an Ethernet local computer network: an experimental study
Author: Gonsalves, Timothy A.
Date: February 1982
Abstract: Local computer networks have been used successfully for data applications such as file transfers for several years. Recently, there have been several proposals for using these networks for voice applications. This paper describes simple voice protocol for use on a packet-switching local network. This protocol is used in an experimental study of the feasibility of using a 3 Mbs experimental Ethernet network for packet-voice communications. This study shows that with appropriately chosen parameters the experimental Ethernet is capable of supporting about 40 simultaneous 64 Kbps voice conversations with acceptable quality. This corresponds to a utilization of 95% of the network capacity.
