Embodiment 1

[0061] like figure 1 As shown, Embodiment 1 of the present invention provides a synchronous planning method, which specifically includes the following steps:

[0062] Step S101: After obtaining the topology change information of the network element or link, determine the network structure where the network element or link is located.

[0063] The topology change information mentioned here refers to change information such as deleting or adding or adjusting network elements or links in the synchronous network. Among them, the network structure includes: a ring structure and a chain structure. The so-called star structure can be regarded as a chain structure, and the network structure can be regarded as a combination of multiple ring structures. The topology change information includes network elements or chain structures. According to the identity information of the link, the network structure where the network element or link is located can be found out according to the ident...

Embodiment 2

[0070] The first embodiment above briefly introduces the implementation of the synchronous planning method of the present invention, which will be further described below in conjunction with the accompanying drawings.

[0071] Specifically, such as figure 2 As shown, the synchronous planning method includes the following steps:

[0072] Step S201: Obtain topology change information of network elements or links.

[0073] Among them, there are many ways to obtain the topology change information of network elements or links, such as network element reporting or automatic acquisition. Taking network element reporting as an example, each network element in the synchronization network detects its own information in real time. When the physical connection relationship between adjacent network elements changes, it actively reports the topology change information. In this way, topology change information of network elements or links in the synchronous network can be automatically ob...

Embodiment 3

[0094] The second embodiment above introduces the synchronous planning method of the present invention in detail in combination with a ring link scenario, and will further explain it in combination with a chain link in the following.

[0095] Specifically, such as image 3 As shown, the synchronous planning method includes the following steps:

[0096] Step S301: Obtain topology change information of network elements or links.

[0097] Among them, there are many ways to obtain the topology change information of network elements or links, such as network element reporting or automatic acquisition. Taking network element reporting as an example, each network element in the synchronization network detects its own information in real time. When the physical connection relationship between adjacent network elements changes, it actively reports the topology change information. In this way, topology change information of network elements or links in the synchronous network can be a...

Abstract

The invention discloses a synchronous planning method and device. The method includes: after acquiring topology change information of a network element or a link, determining the network structure where the network element or link is located; Network structure, determine the network area that needs to be planned synchronously; perform synchronous planning on the network elements in the network area that needs to be planned synchronously. The present invention accurately and comprehensively determines the changed network area by automatically acquiring network element or link topology change information, and performs clock time synchronization planning for network elements in the network area, improves planning accuracy, and avoids incomplete planning and Misplanning causes degradation of network synchronization performance. In addition, the topology change perception is automatically completed, and the network area that needs to be synchronized is automatically delineated without manual participation, which can greatly reduce the workload and increase the speed of synchronous network element provisioning after new additions and adjustments.

Description

technical field [0001] The invention relates to the fields of transmission and IP, in particular to a synchronization planning method and device. Background technique [0002] With the development of communication technology, the services carried by the communication network show a trend of developing from a single voice service to a diversified data service, video service, and cloud service. In order to ensure the normal operation of various communication services, service network equipment, transmission equipment and wireless equipment need to support clock frequency synchronization and time synchronization. For Time Division Multiplexing (TDM, TimeDivision Multiplexing) services, if the clock frequency of the sending device is faster than that of the receiving device, the receiving device will periodically miss reading the information sent by the sending device; if the clock frequency of the sending device is slower than that of the receiving device, the receiving device ...
