Description

Ethernet is the most popular LAN technology. Its low price and robustness, resulting from its wide acceptance and deployment, has created an eagerness to expand its responsibilities to the factory-floor, where real-time requirements are to be fulfilled. However, it is difficult to build a real-time control network using Ethernet, because its MAC protocol, the 1-persistent CSMA/CD protocol with the BEB collision resolution algorithm, has unpredictable delay characteristics.Many anticipate that the recent technological advances in Ethernet such as the emerging Fast/Gigabit Ethernet, prioritization, micro-segmentation and full-duplex operation using switches will also enable it to support time-critical applications.This talk will look at the unpredictability inherent to Ethernet and at recent technological advances towards real-time operation. It will also address recently introduced features such as spanning tree protocols, port trunking and virtual LANs which may potentially enable flexibility and mobility in distributed time-critical systems.
