Abstract

In this paper two protocols integrating voice and data on a token bus LAN are proposed. These protocols use the access mechanism of the Token Bus protocol, but in addition the token bypasses idle stations, exploiting the periodicity of voice. The priority scheme of the Token Bus is used to separate voice traffic from data traffic. Voice packets are assigned to the higher priority while data packets and the voice call packets for setting up calls are assigned to the lower priority. The proposed protocols were studied via simulation tools. The simulation results show that these protocols satisfy the delay constraint of voice traffic, and at the same time, guarantee a sufficient bandwidth for data traffic. Results obtained under various traffic conditions are given.
