Packet voice communicatins over PC based local area networks

Abstract

This paper presents actual implementations of packet voice communication systems over two types of PC based local area networks. One is a token-passing ring network and the other is an Ethernet network. The system configuration, system operation and system performance analysis is described for both networks. A formula for the maximum allowable number of active voice stations is presented for both systems. The last part of the paper describes a proposed design for a distributed packet voice communications protocol. The protocol presented deals with the higher levels of the communication system. The purpose of the protocol is to establish and maintain a telephone conversation between two users by using the underlying network services.
