The Study of Time Delay and Performances Evaluation Architecture for Control Network
In order to evaluate the real time property, stability and deterministic of ControlNet fieldbus, a simple and effective transmission time delay model was proposed to analyze the characteristic of virtual token passing (VTP) mechanism. Then, the maximum transmission time delay in the scheduled part of network update time can be determined. According to the contribution of the transmission time delay to the network throughput, a new performance evaluation architecture, which includes the network efficiency, network utilization, packet loss rate and throughput, was given to value the network real time property, deterministic and stability.
