Embodiment 1

[0032] Embodiment 1: as figure 2 As shown, the present embodiment provides a hardware-based MRP ring network redundancy processing system, including,

[0033] The switch chip 1 receives the protocol message uploaded by the media redundancy management node MRM in the MRP ring network, transmits the protocol message to the processor 2 or the hardware coprocessor 3, and receives the message returned by the processor 2 or the hardware coprocessor 3 Process the result, and operate the media redundancy management node MRM according to the processing result; generally, this operation refers to: switch chip 1 changes a port of the MRM from BLOCKED to FORWARDING state; controls the MRP ring network to open, and creates and restores the topology Structured network communication.

[0034] The hardware coprocessor 3 receives the offline frame message LinkDown uploaded by the switch chip 1, responds to the message and returns the processing result to the switch chip 1; in this emb...

Embodiment 2

[0042] Embodiment 2: as Figure 6 As shown, in this embodiment, the hardware coprocessor 3 is located between the processor 2 and the switch chip 1, which not only improves the transmission rate, but also saves the use of the switch chip pins. In this mode, the switch chip 1 needs to receive The received messages (referring to the offline frame message LinkDown, the test frame message Test, and the topology change frame message Topology Change) are all transmitted to the processor 2 through the hardware coprocessor 3 .

Embodiment 3

[0043] Embodiment 3: as image 3 As shown, this embodiment provides an MRP ring network redundancy processing method with faster processing speed and shorter response time for the offline frame message LinkDown, including the following steps:

[0044] S100: The switch chip 1 receives the message uploaded from the media redundancy management node MRM in the MRP ring network, and judges whether the message is an offline frame message LinkDown, and if so, transmits it to the hardware coprocessor 3; otherwise, uploads it To the processor 2, generally speaking, the message uploaded by the media redundancy management node MRM includes the offline frame message LinkDown, the test frame message Test, and the topology change frame message Topology Change; that is, in this embodiment, the switch chip 1 The offline frame message LinkDown will be uploaded to the hardware coprocessor 3, and the test frame message Test and the topology change frame message Topology Change will be uploa...

Abstract

The invention relates to the technical field of MRP (Media Redundancy Protocol) ring networks and particularly relates to a MRP (Media Redundancy Protocol) ring network redundancy processing system and method based on hardware. The MRP ring network redundancy processing system responds to and processes a LinkDown frame message uploaded by a switch chip by arranging a hardware coprocessor; as the coprocessor is short in response time, fast in processing speed and small in delay jitter, time for recovering network communication is greatly shortened, the packet loss ratio is reduced, and the switch performance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of MRP ring network, in particular to a hardware-based MRP ring network redundancy processing system and method. Background technique [0002] MRP (Media Redundancy Protocol) is a media redundancy protocol. Aiming at the high reliability requirements of industrial communication networks, the ring-type redundant network established by using the MRP protocol can avoid ring network hazards and quickly recover when a fault occurs. A new network topology is established to restore network communications. Usually the MRP ring network is composed of a media redundancy management node MRM and multiple media redundancy client nodes MRC. Common MRP ring open processing mechanism is as follows: figure 1 As shown: the link of the ring network is disconnected, MRM will receive the port offline frame (LinkDown Frame) of MRC1 or MRC2, the switch chip will submit the LinkDown message to the processor, and the processing re...
