Real-time voice and data integration in token ring LAN

Analytical and simulation models developed for the voice and data integrated token ring local area network (LAN) based on the IEEE 802.5 standard are presented. In the model, a simple concept termed the equivalent load representation is introduced to handle both voice and data traffic in the network. This technique can be extended to handle multimedia services in a token ring network. Using extensive simulation of the network, the integrity of the model was verified. From the simulation, the following results were derived: (a) optimal range for voice packet length; (b) relationship between voice packet delay and number of voice stations; (c) maximum number of voice stations supported by the network; (d) relationship between data and voice traffic in the same network; and (e) statistical characteristics of voice packet delay. Both the analytical and simulation models derived provide practical design rules for implementing voice/data integrated service in a token ring network using existing technology and standards
