Abstract:
A method includes receiving traffic through a first interface in a first group of interfaces at a switch. The first group of interfaces is associated with a first virtual network. The method also includes determining that the traffic is destined for a destination associated with a second virtual network and forwarding the traffic to a second interface in a second group of interfaces at the switch. The second group of interfaces is associated with the second virtual network. The method further includes filtering the traffic that is received at the second interface in the second group of interfaces and communicating the filtered traffic towards the destination. The first and second virtual networks could represent Virtual Local Area Networks associated with different network levels of a process control system.
