Description

Synchronous planning method and device
Technical Field
The present invention relates to the field of transmission and IP, and in particular, to a synchronization planning method and apparatus.
Background
With the development of communication technology, services carried by a communication network show a trend from a single voice service to diversified data services, video services and cloud services. In order to ensure the normal operation of various communication services, service network equipment, transmission equipment and wireless equipment all need to support clock frequency synchronization and time synchronization. For Time Division Multiplexing (TDM), if the clock frequency of the sending device is faster than that of the receiving device, the receiving device will periodically skip 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 will periodically re-read the information sent by the sending device. And accurate time synchronization is needed among the base stations, otherwise, base station interference is caused, and even call connection cannot be established.
In the process of network construction and operation and maintenance, the network often has cutover adjustment and the like, and when a network element or a link is newly added and adjusted, in order to ensure that all devices in the network can correctly transmit or acquire frequency synchronization and time synchronization signals, synchronous planning and configuration are required to be carried out again.
In the prior art, network topology changes are caused after network elements or links are newly added and adjusted in a network. If the original synchronization configuration is adopted, the synchronization path may be changed or the synchronization signal may be degraded. Therefore, engineering or operation and maintenance personnel need to manually plan a clock and a time synchronization path each time cutting, connecting and adjusting, and then perform synchronous configuration on equipment one by one according to the plan. When the newly added and adjusted network elements or links relate to inter-domain synchronization of different network managers, a plurality of projects or operation and maintenance personnel are required to utilize the different network managers to work cooperatively.
Because the structure of the synchronous network is complex, the upstream equipment on the synchronous path has a large influence on the downstream equipment, and after the network elements or links are newly added and adjusted, the synchronization of other network elements can be influenced besides the network elements or links involved in the direct adjustment. Manually demarcating all affected areas, and re-performing synchronous path planning and synchronous configuration is difficult, so that missing configuration and wrong configuration are easy to occur, which causes abnormal synchronization and reduced synchronization performance, and even a synchronous timing loop occurs. In addition, the engineering or operation and maintenance personnel discover and respond to the synchronous change caused by the network topology change, the work of the planning of the affected area, the planning of the synchronous path, the synchronous configuration and the like is also finished manually, the process is complicated, the time consumption is long, the difficulty is high, the requirement on the technical level of personnel is high, and the opening speed of the synchronous network element after the new addition and the adjustment is reduced.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
As shown in fig. 1, a first embodiment of the present invention provides a synchronous planning method, which specifically includes the following steps:
step S101: and after the topology change information of the network element or the link is obtained, determining the network structure where the network element or the link is located.
The topology change information here refers to change information such as deleting or adding or adjusting network elements or links in the synchronous network. Wherein, the network structure includes: the topology change information includes the identity information of the network element or link, and the network structure where the network element or link is located can be found according to the identity information.
Step S102: and determining a network area needing synchronous planning according to the network structure where the network element or the link is located.
It is worth pointing out that different network structures affect different ranges, and therefore, when a network area needing synchronous planning is defined, the network structure where a changed network element or link is located needs to be defined. And if the network element or the link is newly added, judging by using the network structure after the network element or the link is newly added, and if the network element or the link is deleted, judging by using the network structure before the network element or the link is deleted.

Specifically, according to the network element identity information and the information of the connection relationship, the synchronization configuration and the synchronization information of the network element or the link in the network area that needs to be synchronously planned are obtained, and then the synchronous planning is performed on the network element or the link, wherein the synchronous planning refers to clock frequency synchronization and/or time synchronization.
In conclusion, by automatically acquiring the topology change information of the network element or the link, the changed network area is accurately and comprehensively determined, the clock time synchronization planning is performed on the network element in the network area, the planning accuracy is improved, and the problem of network synchronization performance deterioration caused by incomplete planning and wrong planning is avoided. In addition, topology change perception is automatically completed, a network area needing synchronous planning is automatically planned, manual participation is not needed, workload can be greatly reduced, and the opening speed of the synchronous network element after addition and adjustment is improved.
Example two
The above embodiment briefly introduces an embodiment of the synchronization planning method of the present invention, which will be further described with reference to the accompanying drawings.
Specifically, as shown in fig. 2, the synchronous planning method includes the following steps:
step S201: and acquiring the topology change information of the network element or the link.
The method for acquiring the topology change information of the network element or the link includes various manners, such as network element reporting or automatic acquisition, taking network element reporting as an example, when each network element in the synchronous network detects the information of itself in real time, and when a physical connection relation between the network element and an adjacent network element is detected to be changed, the topology change information is actively reported. Therefore, the topology change information of the network elements or links in the synchronous network can be automatically acquired.
In addition, the obtaining of the topology change information of the network element or the link can be realized according to the following modes: and acquiring topology information reported by the network element, and comparing the topology information with a previously constructed network topology structure to generate topology change information.
Each network element in the synchronous network reports its own topology information periodically, wherein the topology information carries the physical connection information of the corresponding network element, and the system can construct a network topology structure of the complete synchronous network according to the topology information of each network element. The specific network topology structure may be constructed based on a network topology discovery method of a Simple Network Management Protocol (SNMP) or based on an Open Shortest Path First (OSPF).
After the topology information reported by each network element is acquired, the topology information is compared with a previously constructed network topology structure in a traversing way, namely whether the network element is changed or not is determined, and the topology change information is generated. Taking a network element as an example, if topology information reported by a certain network element does not exist in a previously constructed network topology structure, that is, the network element is a newly added network element or a certain port or connection relationship of the network element changes, which means that the system senses that an original network topology structure changes, and generates topology change information carrying topology information of a corresponding network element. It should be noted that the above comparison method is only one of the methods for acquiring topology change information, and other acquisition methods may also be applied to the embodiments of the present invention.
Step S202: traversing the previous network topology starting from a network element or link.
After the topology change information of the network element or the link is obtained, the previous network topology structure is traversed by taking the network element or the link as a starting point.
Step S203: and when the network element or the link passes through the starting point again in the traversal process, determining that the network structure where the changed network element or link is located is a ring network.
And traversing by using a depth-first algorithm with the changed network element or link as a starting point, terminating the traversing process if the changed network element or link is traversed to the starting network element or link, determining that the changed network element or link is in the ring network, and recording each network element or link in the ring network. It should be noted that the traversal method is only one implementation of multiple methods for determining the ring structure, and other methods or algorithms for determining the ring structure are applicable to the embodiment of the present invention, and are not described in detail herein.
Step S204: when the network structure where the network element or the link is located is a ring network, determining that the network area needing to be synchronously planned is the ring network where the network element or the link is located.
Because the synchronous influence ranges of different network structures are different, when the network structure is a ring network, the network area needing synchronous planning is determined to be the ring network where the changed network element or link is located. After determining the network area that needs to be synchronously planned, synchronously planning the network elements in the network area, where the specific synchronous planning may refer to, but is not limited to, the following method.
Step S205: and constructing a new network topology structure according to the port information of the network elements in the network area required to be synchronously planned and the physical connection relation information between the network elements and the adjacent network elements.
The specific network topology structure can be constructed based on a network topology discovery method of a Simple Network Management Protocol (SNMP) or a network topology discovery method based on protocols such as Open Shortest Path First (OSPF). The network topology structure is automatically updated and constructed, manual participation is not needed, and the workload can be greatly reduced.
Step S206: and determining the master and standby clock source ports and the priority of the network area needing synchronous planning according to the new network topology structure.
And after determining a new network topology structure, configuring master and standby clock source ports and priority for the changed network elements or links.
Step S207: and performing clock synchronization planning and configuration on the network area needing to be synchronously planned according to the master and standby clock source ports and the priority.
The above describes the process of clock frequency synchronization in a synchronous network, and the following describes the implementation process of time synchronization. The method specifically comprises the following steps:
step S208: and determining port information of a network area needing to be synchronously planned, which needs to enable a time synchronization function according to the new network topology structure.
Step S209: and performing time synchronization planning and configuration on the network area needing to be synchronously planned according to the port information needing to enable the time synchronization function.
In addition, when the network structure where the changed network element or link is located is cross-domain, the topology change information is reported to the upper-level system for clock time synchronization planning. That is, when the network topology changes among a plurality of domains due to the addition and adjustment of the network element or the link, and when the topology change information is collected and the inter-domain topology cannot be added or adjusted, the topology change information should be reported to the management system including the inter-domain topology in the previous management or control domain, and the previous level performs planning. The upper-level system can plan an optimal inter-domain path for the cross-domain network region, and then sends synchronous configuration to complete the synchronous planning of the inter-domain network elements.
By automatically acquiring the topology change information of the network elements or links, the changed network area is accurately and comprehensively determined, the clock time synchronization planning is carried out on the network elements in the network area, the planning accuracy is improved, and the problem of network synchronization performance deterioration caused by incomplete planning and wrong planning is solved. In addition, topology change perception is automatically completed, a network area needing synchronous planning is automatically planned, manual participation is not needed, workload can be greatly reduced, and the opening speed of the synchronous network element after addition and adjustment is improved.
EXAMPLE III
The second embodiment above describes the synchronization planning method of the present invention in detail with reference to a ring link scenario, and the synchronization planning method will be further explained with reference to a chain link.
Specifically, as shown in fig. 3, the synchronous planning method includes the following steps:
step S301: and acquiring the topology change information of the network element or the link.
The method for acquiring the topology change information of the network element or the link includes various manners, such as network element reporting or automatic acquisition, taking network element reporting as an example, when each network element in the synchronous network detects the information of itself in real time, and when a physical connection relation between the network element and an adjacent network element is detected to be changed, the topology change information is actively reported. Therefore, the topology change information of the network elements or links in the synchronous network can be automatically acquired.
In addition, the obtaining of the topology change information of the network element or the link can be realized according to the following modes: and acquiring topology information reported by the network element, and comparing the topology information with a previously constructed network topology structure to generate topology change information.
Each network element in the synchronous network reports its own topology information periodically, wherein the topology information carries the physical connection information of the corresponding network element, and the system can construct a network topology structure of the complete synchronous network according to the topology information of each network element. The specific network topology structure may be constructed based on a network topology discovery method of a Simple Network Management Protocol (SNMP) or based on an Open Shortest Path First (OSPF).
After the topology information reported by each network element is acquired, the topology information is compared with a previously constructed network topology structure in a traversing way, namely whether the network element is changed or not is determined, and the topology change information is generated. Taking a network element as an example, if topology information reported by a certain network element does not exist in a previously constructed network topology structure, that is, the network element is a newly added network element or a certain port or connection relationship of the network element changes, which means that the system senses that an original network topology structure changes, and generates topology change information carrying topology information of a corresponding network element. It should be noted that the above comparison method is only one of the methods for acquiring topology change information, and other acquisition methods may also be applied to the embodiments of the present invention.
Step S302: traversing the previous network topology starting from a network element or link.
After the topology change information of the network element or the link is obtained, the previous network topology structure is traversed by taking the network element or the link as a starting point.
Step S303: and when the network element or the link of the starting point is not passed through again in the traversal process, determining that the network structure where the changed network element or link is located is a chain network.
And traversing by using a depth-first algorithm with the changed network element or link as a starting point, and if the traversing process is finished but does not pass through the network element or link of the starting point again, determining that the changed network element or link is in the chain network. It should be noted that the traversal method is only one implementation of various methods for determining the chain structure, and other methods or algorithms for determining the chain structure are applicable to the embodiments of the present invention, and are not described in detail herein.
Step S304: when the network structure where the network element or link is located is a chain network, determining that the network area needing synchronous planning is the network element or link and the adjacent network elements or links.
Because the synchronous influence ranges of different network structures are different, when the network structure is a chain network, the network area needing synchronous planning is determined to be the changed network element or link and the adjacent network elements or links. After determining the network area that needs to be synchronously planned, synchronously planning the network elements in the network area, where the specific synchronous planning may refer to, but is not limited to, the following method.
Step S305: and constructing a new network topology structure according to the port information of the network elements in the network area required to be synchronously planned and the physical connection relation information between the network elements and the adjacent network elements.
The specific network topology structure can be constructed based on a network topology discovery method of a Simple Network Management Protocol (SNMP) or a network topology discovery method based on protocols such as Open Shortest Path First (OSPF). The network topology structure is automatically updated and constructed, manual participation is not needed, and the workload can be greatly reduced.
Step S306: and determining the master and standby clock source ports and the priority of the network area needing synchronous planning according to the new network topology structure.
And after determining a new network topology structure, configuring master and standby clock source ports and priority for the changed network elements or links.
Step S307: and performing clock synchronization planning and configuration on the network area needing to be synchronously planned according to the master and standby clock source ports and the priority.
The above describes the process of clock frequency synchronization in a synchronous network, and the following describes the implementation process of time synchronization. The method specifically comprises the following steps:
step S308: and determining port information of a network area needing to be synchronously planned, which needs to enable a time synchronization function according to the new network topology structure.
Step S309: and performing time synchronization planning and configuration on the network area needing to be synchronously planned according to the port information needing to enable the time synchronization function.
In addition, when the network structure where the changed network element or link is located is cross-domain, the topology change information is reported to the upper-level system for clock time synchronization planning. That is, when the network topology changes among a plurality of domains due to the addition and adjustment of the network element or the link, and when the topology change information is collected and the inter-domain topology cannot be added or adjusted, the topology change information should be reported to the management system including the inter-domain topology in the previous management or control domain, and the previous level performs planning. The upper-level system can plan an optimal inter-domain path for the cross-domain network region, and then sends synchronous configuration to complete the synchronous planning of the inter-domain network elements.
By automatically acquiring the topology change information of the network elements or links, the changed network area is accurately and comprehensively determined, the clock time synchronization planning is carried out on the network elements in the network area, the planning accuracy is improved, and the problem of network synchronization performance deterioration caused by incomplete planning and wrong planning is solved.
