Embodiment 1

[0061] Such as figure 1 As shown, the embodiment of the present invention provides a method for automatically maintaining a clock synchronization network based on network configuration changes. The main process of the method includes:

[0062] Step 100: Receive a network topology change message that affects clock synchronization input configuration and identify affected devices, process fiber connections between affected devices according to the network topology change message, and only retain the unique preferred fiber connection. This step receives and processes the change message of the network topology in the management and control system, and then preprocesses the clock synchronization input configuration, and only retains the only preferred fiber connection. It should be noted that when there are batch configuration change messages, iterative processing is performed in time sequence, and each iteration forms a closed loop with preprocessing and incremental planning of su...

Embodiment 2

[0096] This embodiment 2 is based on the foregoing embodiment 1, and further describes the present invention by using an example of a specific implementation scenario. This scenario is the automatic planning when network cutover scenarios are broken and points are added.

[0097] Such as Figure 6 Shown is a schematic diagram of the minimum ring calculation in this embodiment. Such as Figure 6 As shown on the left, an access ring is newly added due to capacity expansion, and the management and control system performs a cutover operation to break the ring and add a point (new equipment 1). At this time, the clock automatic planning module receives the new Add fiber connection messages, and identify the newly added equipment; the planning module takes the newly added equipment as the starting point, and calculates its minimum ring structure in the network, such as figure 2 As shown in the dotted box on the right, the smallest ring includes device 1, device 3, and device 5. ...

Embodiment 3

[0102] On the basis of the method for automatically maintaining the clock synchronization network based on the network configuration change provided by the above-mentioned embodiment 1 and embodiment 2, the present invention also provides a device for automatically maintaining the clock synchronization network based on the network configuration change that can be used to implement the above method ,Such as Figure 12 Shown is a schematic diagram of the device architecture of the embodiment of the present invention. The device for automatically maintaining a clock synchronization network based on network configuration changes in this embodiment includes one or more processors 21 and memory 22 . in, Figure 12 A processor 21 is taken as an example.

[0103] The processor 21 and the memory 22 may be connected via a bus or in other ways, Figure 12 Take connection via bus as an example.

[0104] The memory 22, as a non-volatile computer-readable storage medium, can be used to ...

Abstract

The invention discloses a method and device for automatically maintaining a clock synchronization network based on network configuration change, and the method comprises the steps: receiving a network topology change message which affects clock synchronization input configuration, recognizing affected equipment, carrying out the processing of connection fibers between the affected equipment according to the network topology change message, and only reserving a unique optimal connection fiber; the minimum ring or the shortest chain of the device in the network is calculated by taking the device lacking the clock synchronization input configuration as a starting point, and the main clock synchronization input configuration and the standby clock synchronization input configuration of the whole are selected by taking the minimum ring or the shortest chain as the whole; re-planning clock synchronization input configuration of the internal equipment of the minimum ring or the shortest chain according to a ring network priority principle; and calculating and downloading incremental clock synchronous input configurations of all the devices to complete dynamic incremental planning of the clock synchronous input configurations. The dynamic planning method can be better suitable for stock network maintenance.

Description

technical field [0001] The invention belongs to the technical field of bearer network construction and deployment, and more specifically relates to a method and device for automatically maintaining a clock synchronization network based on network configuration changes. Background technique [0002] With the rapid development of 5G technology in 2B industry applications, more and more bearer network services require low latency and high-precision clock synchronization, and the requirements for clock synchronization networks are getting higher and higher. [0003] At present, for the maintenance and management of the clock synchronization of network element equipment in the bearer network, the main method is to manually plan from the management and control system, and configure the tracking path of the clock synchronization network station by station. When the site is frequently adjusted, the operator needs to spend a lot of manpower to adjust the synchronization network, whic...
