cables), network switches and even network interfaces. Media redundancy describes concepts that compensate for breakdowns in a distributed network system, including network media (e.g. A communication network is designed in such a way that it can compensate for the breakdown of a communication link through a standby and failover mechanism to a secondary network connection. Network media redundancy is a concept that concentrates on communication network redundancy. However, complete system redundancy is the most expensive way of high availability. High availability can be achieved by using complete system redundancy – every device is doubled using duplicated SCADA systems, servers, controllers, sensors and actuators, as well as duplicated networks.Īs every component is available two times independently, any random failure should not influence the system, as long as the second system continues to run properly. This is because it is easier to control from a central console as the management software just needs to communicate with the switch to get full traffic management features.THE FAILURE of certain components in factory automation, process industry or substation automation applications, which never can be totally avoided, have to be handled in a way that minimises the influence to the system. The best cabled network topology for large businesses is the star topology. What is the best network topology for a large business? The goal is to duplicate any required component whose failure could disable critical applications. Redundancy attempts to eliminate any single point of failure on the network.
If a break occurs in a segment of cable, traffic can still be rerouted using the other cables. Characteristics of a mesh topology are as follows: A mesh topology provides redundant links across the network. Which network topology has redundant paths?Įvery component of the network is connected directly to every other component. Now, we have got the complete detailed explanation and answer for everyone, who is interested! This is a question our experts keep getting from time to time. Which topology offers the highest level of redundancy?
