Abstract
The Token Bus, IEEE 802.4, provides high priority message options. The delay of high priority messages becomes an important criterion in the design and management of computer communication networks. A goal of the protocol is to allocate sufficient bandwidth and frequency of access to minimize of the high priority message delay. In this study, a simulation model of a priority based network, consisting of two token bus networks interconnected by a bridge is implemented. The load distribution among stations is asymmetric and the messages are divided into two priorities, high and low. Both fixed and variable token token holding times for each station to transfer high priority message, two different approaches are considered and implemented. In the variable case token hold may vary according to the local and global load. The simulation results show that the variable high priority token holding time approach can reduce the high priority message delay.
