Abstract :
This paper provides several research results about a technique of high quality telephony over LAN. Firstly, the value of the technique is discussed. Secondly, the delay performance of Ethernet LAN is tested by experiments both for the network layer and the application layer. Thirdly, a software architecture orientated to a real-time process like speech communication is proposed against the major reason of the overall transmission delay. Finally, as a conclusion, the possibility of realizing high quality telephony over LAN is demonstrated.
