Abstract:
Industrial Ethernet is a new trend in technology designed to replace the traditional
industrial solutions such as point to point and field bus systems. This paper studies
Industrial Ethernet performance under different circumstances using the network simulation
package(OPNET). Firstly, a validation procedure to the use of OPNET in simulating such
networks was made by comparing OPNET performance with practical experiments once
and then with analytical models results. Then OPNET was used to study the effect of
different parameters on the real time performance of the network. It was found that some
parameters like (packet length, number of nodes and packet production rate) have minor
effect on the network performance, while the others (packets processing rate and FTP
traffic transferred to an industrial node) could affect seriously on the network behavior.
