3 Introduction: Parallel Redundacy Protocol (PRP) PRP nodes (Dual Attached Nodes DANs), are connected to two independent Ethernet networks (LAN A and LAN B) DAN nodes send the same frames over both networks DAN DAN Fault free state: Destination nodes consume the first received frame and discard the duplicates SAN LAN A LANB Fault state: the frames will still be transmitted and received through the other SAN RedBox SAN SAN Non PRP nodes can be attached to a single Network VDAN VDAN

4 Introduction: PRP PRP Frame Format Redundancy Control Trailer (RCT): 16bit sequence number 4bit LAN identifier 12bit Frame Size (additional check) 16 bit PRP suffix 0x88FB (new in Ed. 2) Duplicate Discard Algorithm Open to different implementations Occasional acceptance of a duplicate is tolerated RCT dest_addr scr_addr type LSDU padding sequence repair Lan size PRP sufx FCS

5 Introduction: PRP Network Supervision Monitor the status of each node and LANs Each DAN sends periodically a Supervision Frame Supervision Frame Format: Multicast by each DANP over both ports every LifeCheckInterval VLAN tag optional MAC addresses Protocol version Mode of operation supported Supervision frames sequence number

6 Introduction: High availability Seamless Redundancy (HSR) SOURCE DESTINATIONS SAN SAN SAN HSR nodes (Dual Attached Nodes with HSR protocol s), are provided with two Ethernet ports C_frame A_frame (HSR) D_frame B_frame (HSR) switch Red Box Interlink Provide redundancy by sending duplicate packets in both directions B A Multicast and Unicast operation DESTINATIONS Typical configuration: rings and ring of rings SOURCE SAN SAN SAN SANs must be connected through a RedBox C_frame switch Red Box Interlink Deterministic (Worst Case Scenario) A_frame (HSR) B_frame (HSR) D_frame DESTINATION
