A tunnel ventilation system that loses network connectivity could have fatal consequences. Having high redundancy is essential to prevent downtime. The combination of FRNT, multiple VLANs, and VRRP in a Westermo network provides extreme redundancy.
To build an extremely redundant and secure network connection between tunnels a Westermo network utilizes FRNT, a network ring protocol that supports up to 200 network switches in Ring configuration size with 20ms network recovery time. Link aggregation further enhances redundancy. VRRP, Virtual router redundancy protocol, allows the Lynx 5512 to act as redundant gateways, while zoning according to 62443 cyber security standards enhances security.
