The present invention relates to electronic systems for use in high demand or mission critical environments, including power stations, sub-stations, roadside transportation, rail, and industrial applications. The present invention provides a) increased resilience of mission critical communications infrastructure b) ability to maintain multiple independent RSTP domains over HSR ring d) method of using a hidden VLAN as an RSTP domain ID c) a method of creating multiple redundant protocols domains over HSR ring.

Multiple RSTP domain separation

The present invention relates to an environmentally robust critical infrastructure security framework for network use in high demand or mission critical environments and applications, including but not limited to power stations, sub-stations, intelligent transportation systems (ITS), rail, traffic control systems, chemical, oil & gas, critical manufacturing, and industrial applications is disclosed (e.g. complaint to most advanced industrial and military applications). The present invention provides a simple yet effective method suitable for critical infrastructure operations, their systems and protocol requirements. The framework includes role based access control (RBAC) down to each intelligent electronic device (TED), programmable logic controller (PLC), etc. regardless of the type of the device and without the need to have support at the IED level for specific requirements.
