Dynamic Network Reconfiguration and Transparent Failover in Fieldbus Protocol (PESNet)
Yoon-Soo Lee · 한국통신학회논문지 · 2008
The dynamic network reconfiguration feature for a network can be important to applications where nodes in a network may be removed or added. Here, a discussion about how a network can be dynamically reconfigured in a fieldbus protocol which operates in a counter rotating dual ring topology and behaves in a master-slave oriented fashion is made. The focus is on what the roles of the master node and the slave nodes are during network reconfiguration. Moreover, a method to allow failover between redundant nodes in the network is also mentioned in order to take advantage of the dynamic network reconfiguration feature. While the discussion is focused on modifications to be made on PESNet, the idea can be easily employed to any protocol that behaves in a master-slave fashion.
