HSR-PRP Switch Core

3-port Reference for Non Redundant Network VS Zerro Switch-Over Reliable Network

Overview

This IP implements bumpless Ethernet connectivity ensuring zero-delay recovery time in case of network failure and no-frame lost.  The IP supports version 3 of High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) with redundant IEEE 1588-2008. The flexibility and scalability of this IP offers optimized solutions for cost-sensitive CPU-less equipments and for high-end complex MPSoC based networking platforms.

It is a flexible solution for the Energy Market Equipment that will be connected to HSR rings, PRP Lans, or will work as Network bridges in the context of IEC 61850.

Key Features
