High-Availability Seamless Redundancy Ethernet Reference Design for Substation Automation for Linux®
Description
This reference design implements a solution for high-reliability: low-latency network communications for substation automation equipment in Smart Grid transmission and distribution networks. It supports the high-availability seamless redundancy (HSR) specification in the IEC 62439 standard. This solution is a lower-cost alternative to FPGA approaches and provides the flexibility and performance to add features such as IEC 61850 support without additional components. This solution: based upon the Linux High-Level Operating System: may also apply to other markets that need minimum-latency reliability on Ethernet networks such as Factory Automation: Transportations: and others.
Features
- Compliant to IEC 62439-3 Clause 5 specification for HSR ethernet communicationsTraffic filtering based on VLAN IDs: multicast and broadcast support: and built-in storm prevention mechanismZero recovery time in case of network failureDual-ported: full-duplex 100Mbps ethernetFully programmable solution based on the Linux high-level operating system prvodes platform for integration of additional applications
