High-Availability Seamless Redundancy Ethernet Reference Design for Substation Automation for Linux®

1 января 2018

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.

Особенности

Compliant to IEC 62439-3 Clause 5 specification for HSR ethernet communications Traffic filtering based on VLAN IDs, multicast and broadcast support, and built-in storm prevention mechanism Zero recovery time in case of network failure Dual-ported, full-duplex 100Mbps ethernet Fully programmable solution based on the Linux high-level operating system prvodes platform for integration of additional applications
