Problems solved by technology

However, the manual operation is cumbersome, and it will consume a lot of manpower and time for complex on-site application scenarios, wasting labor costs
When the slave node rotation training configuration method is adopted, when the non-FEC mode synchronization problem causes the service to be unavailable, the rotation training configuration method at this time will be invalid

application example 1

[0107] In this application example, the operation process of selecting a certain FEC node mode synchronization in the network is as follows:

[0108] (1) The control unit configures the master node FEC transmission mode of a certain FEC node in the network;

[0109] (2) The control unit detects the state of the state machine;

[0110] (3) Detect whether the state machine is in the Error state, if so, jump to execute (1), otherwise continue to execute (4);

[0111] (4) The slave node receives the FEC working mode synchronization data packet, and verifies the destination address, source address, Ethernet rate of the master node, optical module type of the master node, FEC mode of the master node and data packet in the received synchronization data packet synchronization status. Check that the address of the slave node is consistent with the destination address of the synchronization packet and the Ethernet rate of the master node and the Ethernet rate of the slave node are wit...

application example 2

[0116] Synchronous data packets are transmitted through the FEC transmission mode constructed by the optical supervisory channel out-of-band transmission.

[0117] In the application scenario, the constructed FEC transmission mode synchronization data packet can be transmitted to the slave node through optical monitoring out-of-band, and the slave node starts the master-slave node FEC mode synchronization process after receiving the specific FEC mode synchronization data packet.

application example 3

[0119] The FEC transport mode isochronous packets constructed by the in-band transport of the electrical monitoring channel.

[0120] In the application scenario, the constructed FEC transmission mode synchronization data packet can be transmitted to the slave node through the in-band mode of business electrical monitoring, and the slave node starts the master-slave node FEC mode synchronization process after receiving the specific FEC mode synchronization data packet.

Abstract

The invention discloses an FEC mode synchronization method and system, a master node and a slave node. The slave node receives a synchronization data packet sent by the master node, and the synchronization data packet comprises an FEC transmission mode of the master node; and the FEC transmission mode of the slave node is adjusted according to the FEC transmission mode of the master node. By constructing the synchronization data packet, the FEC mode of the slave node is automatically synchronized with the master node, and the problem that the FEC mode of the slave node cannot be synchronized with the FEC mode of the master node due to service blockage is solved, so that the efficiency and stability of signal transmission are improved.

Description

technical field [0001] The present invention relates to the field of optical network communication, in particular to a synchronization method in FEC (Forward Error Correction, forward error correction) mode, a master node, a slave node and a system. Background technique [0002] The interface between MAC (Media Access Control Address, Media Access Control) and PHY (PortPhysical Layer, port physical layer) of high-speed Ethernet has evolved from the original XGMII (10Gigabit Media Independent Interface, 10Gb independent of media interface) interface to CGMII (100Gigabit Media IndependentInterface, 10Gb media-independent interface), and at the same time, there are more FEC functional layers on the PHY hierarchy. Among them, the FEC sublayer is located between the PCS (Physical Coding Sublayer, physical coding sublayer) and the PMA (Physical Medium Attachment, physical medium adaptation layer) sublayer, and the signal is pre-processed according to a certain format before being ...
