Counter Rotating Dual Ring Daisy Chained Network for Real-Time Distributed Control Protocol
Yoon-Soo Lee · 한국통신학회논문지 · 2008
The ring topology has been in use in networking for quite some time for simplicity. However, the downside of using the ring topology is for having to worry about link or node failure which can result in network failure. Tolerating faults in the ring topology has been a popular area of research. However, it is hard to incorporate those ideas to a specialized network for distributed control networks. This work shows how the ring network can be improved in terms of performance and reliability for high performance distributed control network. Discussion will be on the ideas to increase throughput and reliability. Specifically, this work contains implementation ideas for fieldbus protocols to tolerate single point of link or node failure and prevent packet loss. Since the suggestion of this work makes it obvious on the improved throughput, the conclusion emphasizes on the reliability gain of the network system by making changes to the traditional ring network. However, the reliability of the network may decrease depending on the reliability of the nodes which consists the network.
