Overview
MRS is an IP Core product that combines SOC-E MES IP Core and HPS IP Core in a single product. This implementation allows to combine regular ethernet ports with HSR/PRP capable ports in an easy way.
MRS implements a multi-port, multi-rate managed ethernet switch with a rich set of layer-2 configurable features as well as user selectable ports supporting High-availability Seamless Redundancy and Parallel Redundancy Protocol (HSR and PRP, IEC 62439-3 Clause 5 and 4 respectively) Edition 4.0 protocols for Reliable Ethernet communications providing zero recovery time.
All these characteristics enable a wide number of applications/sectors where the use of MRS IP Core is key. Automotive, Marine, Aerospace, Defence or Electric are examples of markets where our customers are already applying this technology.
Key Features

Network Management & Monitoring
- IEEE 802.1D Spanning-Tree Protocol (STP) to prevent loops from being formed when switches or bridges are interconnected via multiple paths

- IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) provides link availability in multiple VLAN environments by allowing multiple spanning trees
- Multisession port mirroring capabilities. Ingress and egress mirroring functions to allow copying of frames to a mirror port. Option for mirroring only filtered frames that match a specific data pattern.
- User/network port-level security via IEEE802.1X authentication and MAC-based filtering
- Host access control for only frames specified by the user (destination MAC and/or Ethertype based)
- Per port MAC and switch statistics for managing and debugging purposes
- Wide range of management interfaces to access control and statistics registers (selectable at synthesis time)
- I2C master interface for external device configuration (i.e. an EEPROM memory with non-volatile configuration)
Ring Redundancy Protocols
- High-availability Seamless Redundancy (HSR). It can operate in any of the following modes, which are changeable at runtime:
- Mode H (mandatory, default mode): HSR-tagged forwarding
- Mode M (optional): Mixed forwarding HSR-tagged and non HSR-tagged
- Mode N (optional): No forwarding
- Mode T (optional): Transparent forwarding
- Mode U (optional): Unicast forwarding
- Mode R (optional): For RedBoxes to be connected to an RSTP bridge
- Parallel Redundancy Protocol (PRP). It can operate in any of the following modes, which are changeable at runtime:
- Duplicate Discard (default mode)
- Duplicate Accept (testing only)
Others
- Distributed Switch Architecture (DSA) frame tagging to merge application specific messages to management port and to distribute application specific messages to a specific port
- Exclusive forwarding of known protocol specific frames or custom frames to/from management port
