AS the network expands to connect many devices together, the Ethernet redundancy becomes more critical to ensure production is non-stop. Korenix Technology ’s dual homing technology, contained in the JetNet 4508 and 4508f managed switches, allows different brands of Ethernet devices to connect together and also keeps the redundant Ethernet working in fast recovery.
In many enterprise level applications, users choose a chassis switch as their backbone switch, or select Cisco switches to connect in an upper ring. The benefit of chassis L3 switches is that they can setup IP interface and routing to different IP subnets.
It has high ports and provides different modules, copper or fibre to meet demand in various media interfaces. Additionally, the modules also can be hot swapped and backup each other. Most L3 switches and Cisco switches adapt to standard Rapid Spanning Tree Protocol (RSTP) as their Ethernet redundancy solution.
The switches and ring redundancy protocol in the upper ring will always be first priority over the edge rings or edge switches. Being compatible and working 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 two ports can backup each other. In such an environment, it is beneficial to separate the Super Rings from different VLANs or IP subnets. The two 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 to one port in the switch. The other port connects to a hot standby link, which is being constantly monitored and will switch over in seconds once the active link is disconnected or breaks.
