Adds the application of outer VLAN setting for periodic loopback detection for private network services. Add the configuration of automatic enable loopback detection for private network services. Updated MRPS technology: Currently, transmission systems usually adopt a ring network, and the services carried on MPLS-TP rings are increasing in number and becoming more and more important. MRPS (MPLS-TP Ring Protection Switching) is able to realize rapid protection switching of services in the event of link and single device failures to provide high-quality services for users. Optimized Port Mirroring: With the development of network technology, there is an increasing demand for fast fault location and real-time monitoring of service traffic without affecting services. Port mirroring technology is able to satisfy both of these demands by combining meters through the simple method of copying traffic from one or more ports to another. Solved MSTP: MSTP (Multiple Spanning Tree Protocol) that is, Multiple Spanning Tree Protocol, which is used to eliminate network loops, as well as Spanning Tree Protocol STP (Spanning Tree Protocol) and Rapid Spanning Tree Protocol (Rapid Spanning Tree Protocol). loops and solving broadcast storm problems caused by network loops. Updated MSTP protection: MSTP (Multiple Spanning Tree Protocol) that is, Multiple Spanning Tree Protocol, which is used to eliminate network loops as well as Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP). eliminating network loops and solving broadcast storm problems caused by network loops.

Ultra-long distance network customization

As the demand for smart grid informatization increases, the power communication network shows a trend toward service diversification and packetization. Huawei proposes a power communication solution with soft and hard pipe characteristics, namely a unified bearing solution with SDH rigid hard pipes and IP packet flexible soft pipes, to comprehensively meet the service communication needs of the power system.

OSN3500 equipment mainly transmits video, dispatch calls, RTUs, and other services in the power industry to the control center in a layered manner. The access layer is usually OptiX OSN1500 or OptiX OSN500/550 equipment; the core layer is usually OptiX OSN3500/7500 II equipment.

Perfect Protection Functions

Cross protection: The cross and clock unit are provided by the cross clock board. The cross-clock board adopts 1+1 backup, which can protect the cross unit and clock unit at the same time.

Main control protection: The two GSCC single boards, the working board and the protection board, form a 1+1 hot backup mechanism. When the working system control and communication unit is in normal working mode, the protection system control and communication unit is in backup working mode.

Power protection: Through two PIU boards, two -48V/-60V DC power supplies can be fed at the same time. The two power supplies are backups for each other, if any one of them fails, the other one will be put into working condition, which can still ensure the normal operation of the equipment.

SDH service protection: "Configure unprotected chain", "Configure unprotected ring", "Configure ring-multiplexed segment protection subnet", "Configure linear Multiplexing Segment Protection Subnet (1+1)" and "Configuring Linear Multiplexing Segment Protection Subnet (1:1)" as examples to illustrate the process of end-to-end configuration of SDH protection subnets.
