Increasing compatibility between
Ethernet switches
The new Korenix JetNet 4500 Series Industrial Managed Ethernet Switch provides a solution for the compatibility issue between industrial and commercial Ethernet switches
In some industrial Ethernet applications, industrial Ethernet switches must co-exist with commercial switches The two different types of switches use different network redundant ring topology; commercial switches use standard RSTP protocol, while industrial Ethernet switches use proprietary ring protocol such as Korenix Super Ring

The compatibility will be a critical issue for the system network redundancy.
Korenix JetNet 4500 Dual Homing technology provides a solution for the compatibility issue.
RSTP over Super Ring or Dual Homing is to provide an advanced redundancy network solution by connecting switches running in different redundancy protocols (ie IEEE 802.1w Rapid Spanning Tree Protocol and Super Ring) and extend the network redundancy coverage.
Redundancy is achieved by connecting two ports from two separate switches using Super Ring protocol with two ports of commercial switches using RSTP 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.
Constant monitoring of the hot standby link causes a switch over in seconds once the active link is disconnected or breaks.
The process of switching the backup route from one switch to another is transparent to the user.
Interoperability factors: Less than two seconds, Dual Homing can be taken effective to switch over the redundant network.
Dual Homing technology is full compatible with switches when connecting in RSTP, STP, protocol and Korenix Managed Switches connecting in Super Ring Topology.
