5-3 Dual Homing

Dual Homing provides an advanced redundancy network solution by connecting switches running in different redundancy protocols such as IEEE 802.1w Rapid Spanning Tree Protocol and X-Ring to extend the network redundant coverage. Dual Homing feature can ensure a single or two X-Ring groups with redundant backup when connected to a backbone switch. Redundancy is achieved by connecting two ports from two separate switches using X-Ring ring protocol with two ports of managed switches using other redundancy protocol. An active link where data is transmitted is connected with on port in the switch. The other port connected with another switch is a hot standby link. The hot standby link is being constantly monitored and it will be switched over within seconds once the active link is disconnected or broken. This approach can open up LAN design options and expand device choices. For example, it can permit any industrial PLC devices with Ethernet interfaces to be part of a resilient network. With the implementation of Dual Homing feature, the X-Ring group will be allowed to connect to these backbone core switches and without sacrificing its redundant protections. Below, we show an example of connection diagram on how Dual Homing can be connected with 1 or 2 X-Ring groups.
