Overview
Critical systems demand time-aware high-availability networking. Moreover, the complexity of the modern network infrastructures in these premises overcomes the traditional concept of “managed” device.
RELY-RB is a new concept of intelligent device that integrates advanced field-proven technology for “Zero-Packet Loss” redundant Ethernet, sub-microsecond synchronization and cybersecurity. This device is able to merge the whole LAN with redundant networks, to interconnect PRP and HSR networks and to extend HSR rings via QuadBox operation.
Key Features
- Full in-house design (SOC-E IP Cores) based on a reconfigurable platform, upgradable and customizable
- Support for HSR/PRP “Zero-Packet Loss” redundancy and NTP/PTP sub-microsecond synchronization
- Support for QuadBox operation modes: HSR-HSR, HSR-PRP.
- Simplified management and monitoring via a user-friendly HTTPS web interface or SSH accessible CLI
