Protection

Description

Optical Line Protection

Optical line protection utilizesthe dual transmitter-receiver function ofthe OLPveneer to protect the line fiber with split routing between adjacent sites.

In-board1+1Protection

Intra-board1+1protection utilizesthe dual transmitter-receiver function of theOTU/OLPsingle board, and protects the service by using the split route.

LPT

LPT(Link-state Pass Through) detects and notifies failures of service access points and intermediate networks, helping data communication equipment such as routers to start backup networks for communication in time to ensure normal transmission of important data.

Customer-side1+1Protection

Customer-side1+1protection protectsOTUboards andOChfibersby applyingthe dual transmitter-receiver function ofOLP/SCSboards.

ODUk SNCPProtection

ODUk SNCPprotection protectsthe services transmitted on the OTUboard andthe OChfiberby using the double transmit and receive function of the electrical layer crossover.the OptiX OSNequipment supportsSNCPprotectionfor signals witha crossover granularity ofODUk(k=0,1,2,flex).

TributarySNCPProtection

BranchSNCPprotection utilizes the double transmitter-receiver function of the electrical layer crossover toprotectthe customer-sideSDH/SONETorOTNservices onthe branch access, andOptiX OSNequipment supportsSNCPprotectionfor signalswith a crossover granularity ofODUk(k=0,1).

Description

Tunnel APS

SupportsMPLS-TP TunnelAPS, whichmeans setting up atunnelto protect the workingtunnel, so that when the workingtunnelfails, the services can be switched to the protectedtunnelto protect theservices.OptiX OSNdevices support1:1 Tunnel APSprotection.

PW APS

SupportsMPLS-TP PW APS, whichmeans that anotherPWis set toprotect the workingPW, and when the workingPWfails, the service can be switched to the protectionPWto protect the service.OptiX OSNequipment supports1:1 PW APSprotection.

LAG

LAG(Link Aggregation Group) aggregates multiple physical links to form a logical link with a higher rate to transmit data. The domain of link aggregation is between neighboring devices and is not related to the overall network structure. In Ethernet, links actually correspond one-to-one with ports, so link aggregation is also called port aggregation.

ERPS

ERPS(Ethernet Ring Protection Switching) is based on the Ethernet Link Protection Protocol. The protocol runs in an Ethernet ring network and provides link protection for Ethernet services carried in the ring to improve the availability of Ethernet services.

MC-LAG

MC-LAG(Multi-chassis Link AggregationGroup), i.e., cross-device link aggregation, is used to provide dual-attribution protection for Ethernet services.

LPT

The traditional network mainly realizes protection for service access point failure or intermediate service network failure. When both the service access point and the intermediate service network fail,the LPTfunctioncan be enabledto utilize the backup network for communication to ensure the normal transmission of services.

Protection

Description

LMSP

Linear Multiplexed Segment Protection (LMSP) is an automatic protection inversion utilizing the overhead of multiplexed segments for point-to-point physical networks, providing protection at the multiplexed segment level for services between two nodes.The Linear Multiplexed Segment Protection (LMSP) supported byOptiX OSNdevices includes1+1protection and1:Nprotection.

RMSP

Multiplexed segment shared protection ring is an automatic protection inversion realized by using the overhead of multiplexed segments, which is applicable to the protection of services between ring nodes.OptiX OSNdevices support two-fiber bidirectional multiplexed segment shared protection.

SNCP

SNCPprotection is mainly used to realize the protection of cross-subnet services, and it has the characteristics of double sending and receiving. A subnet can be a chain, a ring, or a more complex network.

Protection

Description

Master cross-clock board1+1backup

The master cross-clock board supports1+1master and backup protection, and the master and backup cross boards are backup for each other. The master cross-clock board and the backup cross-clock board are connected to the service cross-slot at the same time through the backplane bus to protect the cross-service.

Description

Master and crossover support independent inversion, and the default is bound inversion.

Power Backup

TwoPIU/APIUsingle boards adopt hot backup to supply power for the system, when onePIU/APIUsingle board fails, the system can still work normally.

Fan Redundancy

Contains4independent fans for equipment cooling, anyonefan failure will not affect the other fans. When any one fan breaks down, the system canoperate normallyfor 96hoursunder the ambient temperature of-5℃～40℃.
