As networks expand to connect many devices together, Ethernet redundancy becomes more critical to ensure continuous connection and non-stop production Korenix Dual homing technology, equipped in JetNet 4508 and 4508f managed switch, provides the most flexible solution to let different brands of Ethernet devices connect together, and also to keep the redundant Ethernet working in fast recovery

In many enterprise level applications, users choose chassis switch as their backbone switch, or select Cisco switches to connect in an upper ring.
The benefits of such a chassis L3 switch, is that it can setup IP interface and routing different IP subnets.
It has high ports and provides different modules, copper or fibre to meet demand in various media interfaces: the modules also can be hot swap and backup with each other.
Most of those L3 switches and Cisco switches adapting standard Rapid Spanning Tree Protocol (RSTP) as Ethernet redundancy solution.
The switches and ring redundancy protocol in the upper ring will be always considered as first priority than the edge rings or edge switches.
So, how to maintain compatibility and work with the different upper ring redundancy protocol is very important for the edge managed switch.
By connecting the Dual Homing switches to one of the modules, the 2 ports can be backup with each other.
In such environment, it always requests to separate the Super Rings from different VLANs or IP subnets.
The 2 Super Rings can be virtually separated easily and the different VLANs/subnets can be routed by the IP interfaces.
Dual homing provides an advanced redundancy network solution by connecting switches running in different redundant protocols (e.g IEEE 802.1w Rapid Spanning Tree Protocol and Super Ring) to extend the network redundant coverage.
Redundancy is achieved by connecting two ports from two separate switches using Super Ring protocol with two ports of Managed Switches using other redundancy protocol.
An active link where data is transmitted is connected with one port in the switch.
The other port connected with another switch is a hot standby link.
Constantly monitoring, the hot standby link will switch over in seconds once the active link is disconnected or breaks.
