FRNT version 2 is Westermo’s protocol for resilience in switched networks. Contributing to the robustness of the protocol is care when alternative paths are opened to make sure there is full connectivity but never any loops in a network.

With FRNT version 2, the foundation remains and added is the possibility to build more complex LAN structures. An example is a large distribution ring network where subrings can be added extend the LAN. This provides flexibility when building larger LAN structures in terms of distances and number of end devices, while retaining the reliable characteristics of FRNT.

Also new with the release of 4.28 is persistent port monitoring. It is a matter of fact that most attacks against networks today go completely unnoticed. It is very hard, after an attack, to determine that it has occurred and to analyse what has happened. With port monitoring enabled, users can listen to traffic, store it on a fileserver for later analysis, or do real-time surveillance by connecting an intrusion detection system (IDS).
