Jet Ring

Setting up the Jet Ring function (redundant connection) in a network better
protects critical connections against errors and network loops. In addition,
network downtime is reduced to less than 300 ms.
The Jet Ring function can be used to set up a secondary path to the network. A
data transmission safety route is then provided in case there is an abrupt
interruption in a connection. This function is extremely important for industrial
applications because connection errors without safeguards for network downtime
can last several minutes and result in heavy losses.
The Jet Ring protocol is used to optimize secondary communication links and to
ensure very short connection recovery time. The Jet Ring function is used to
automatically identify a switch as the network "Master" and to automatically
block connections. This prevents packets from being broadcast to all secondary
loop segments of a network. If a ring segment is separated from the rest of the
network due to a connection error, the Jet Ring protocol automatically adjust the
ring again to restore the connection between the part of the network that was
separated with the rest of the network.
Step 1
The Jet Ring function in the graphic below is applicable to connecting industrial
managed switches.
