Description

Technical Field

[0001] The invention relates to network communication technology, and in particular to a link protection structure system. Background Art

[0002] With the rapid development of network data, the surge in network traffic, and the emergence of various complex network applications, the self-troubleshooting and self-protection capabilities of serial devices are particularly important. The more complex the network application, the more likely the network equipment will fail or the link will vibrate during operation. If the network equipment fails to take relevant measures in time, the link will be abnormal. Failure of serial related network equipment or abnormal link conditions will cause the entire link network to be abnormal, and relevant protection measures cannot be taken for the link. When the current network equipment has a power failure, it is basically impossible to guarantee that the device can protect the access link. Therefore, in order to solve the above problems, on the one hand, it is necessary to improve the functions of serial devices while ensuring the stability of the link and functions, and on the other hand, it is necessary to ensure the stability of the link and improve the protection and troubleshooting capabilities of the device itself. Summary of the invention

[0003] In order to solve the difficulties described in the background, this patent proposes a link protection structure system, which combines software and hardware to protect the link. Based on the current optical path protection hardware module, it adds circuit protection and software system detection of the downstream optical path, and performs real-time analysis on the interaction of the entire link. In this way, in the case of protection by the optical protection hardware module, electrical protection is also added, as well as the protection ability of the software system to detect and handle abnormalities in the link. First, the device light source protection module is serially connected to the network. When the optical protection fails and power is off, the link will be switched to bypass mode to protect the link. Under abnormal conditions, it supports offline bypass protection and notifies the device of fault log information to ensure that the administrator is notified in time to perform equipment maintenance when the link is continuous. When the optical protection cannot detect abnormal conditions of downstream devices under normal conditions, relevant detection means of downstream devices are required to protect the normal operation of the link. The interface of the serial device that converts optical signals into electrical signals supports circuit protection. When the device fails and the optical path is normal, the optical protection cannot detect abnormalities and cannot protect the link. At this time, the software system of electrical protection can detect relevant electrical signals and make relevant protection measures to notify the device of circuit abnormalities and perform self-protection of the circuit. When the circuit information is normal, the software system will detect the system operation and flow of the equipment in real time and analyze them. If relevant abnormal conditions are detected, relevant protection measures will be implemented to ensure that the flow passes through the equipment normally and achieves the expected effect. Based on the above conditions, triple protection of serial devices is achieved through optical signals, electrical signals and software intelligent detection.

[0004] According to the technical specifications of serial devices, abstract functions and divide their functions into module processes such as Figure 1 As shown, the functional module structure is as follows Figure 2 shown.

[0005] The specific steps are as follows: Step 1: The optical protection module mainly detects the optical path information and performs optical path status switching operations. The detailed steps are as follows: 1. The optical protection module has power-on and power-off protection. The protection status can be controlled by configuration. The power-on status and the power-off status can be configured according to different operating scenarios and different applications of the equipment.

[0006] 2. The optical protection module checks the optical path of the access device. When an optical path abnormality is detected, it can intervene in the optical path according to different types of situations. When link oscillation occurs, protection is performed to ensure the link is normal.

[0007] 3. The optical protection module supports splitting the optical path, and can also copy the traffic to the backend for analysis in bypass state.

[0008] 4. When the optical protection fails due to power outage or the software fails, the abnormal protection mechanism will be triggered. The power failure will start the backup power mechanism and the optical protection abnormal state will be maintained for more than one hour to ensure that maintenance personnel have time to check the abnormality. When the software abnormality cannot be controlled, the protection abnormality alarm will be activated.

[0009] Step 2: The electrical protection module mainly detects circuit information and supports circuit status switching operations. The detailed steps are as follows: 1. The electrical protection module detects the information of the optical-to-electrical module. If an abnormality is detected, a log is recorded and electrical protection operations are performed to ensure that the link is normal.

[0010] 2. The electrical protection module supports direct link shutdown. When a serious abnormality or power failure is detected, the electrical protection module directly shuts down the link, sends a serious problem log, and triggers the optical protection module to work.

[0011] 3. The electrical protection module can also copy traffic to the backend in bypass state.

[0012] Step 3: The system safety module mainly detects relevant status during equipment operation and performs photoelectric protection status switching operations. The detailed detection and protection process is as follows: 1. Automatically detect the memory and CPU usage during the operation of the equipment. If the threshold is exceeded, different levels of alarm information will be given and relevant photoelectric protection switching operations will be performed.

[0013] 2. Detect the message information received by the device. When the number of error messages reaches the threshold, photoelectric protection operation will be performed and logs will be recorded.

[0014] 3. Check the back-end access status of the equipment. When abnormal back-end access or abnormal packet activity status is detected, take relevant photoelectric protection measures and record the log.

[0015] Compared with the prior art, the technical solution of the present invention has the following significant beneficial effects: 1. The optical protection module adds the function of power-off and power-on link protection, and adds a power-off control power supply structure to make up for the defect that the power cannot be controlled after the power is off. It can continue to work within one hour of the power off, ensuring that when the business is normal, sufficient time is provided for troubleshooting and reducing the impact of equipment failure on business functions.

[0016] 2. The electrical protection module uses an interface and processing chip control to make up for the defects that the previous optical protection could not detect.

[0017] 3. The system security module comprehensively detects the operation of the equipment according to the functional system provided by the equipment, takes timely protection measures for the link, and makes up for the defects that the optical protection module and the electrical protection module cannot detect the back-end service status. The software is increased to detect the core key points related to the equipment, and outputs the relevant logs to ensure that the abnormal part is accurately located in a shorter time, saving labor costs and improving work efficiency.

[0018] 4. This system structure can be applied not only to serial devices, but all network security devices can also use this structure system to protect their own traffic security. The photoelectric protection structure system is independent of the relevant business functions of the network equipment, and is simple to apply. It is very convenient and flexible to deploy back-end business based on this structure system. It can integrate modules of all mainstream network devices, and the modules are easy to integrate independently, and the advantage of low cost is obvious. BRIEF DESCRIPTION OF THE DRAWINGS
