Multi-stage network administration system and method for processing northward interface in it

Abstract

This invention discloses a multi-level network management system and North approach interface dealing method in this system, including the adjacent upper and lower network management system which all includes the North approach interface unit used to communicate the information with the external network management system. This interface unit includes: sons management module, used to divide the interfaces in this multi-level network management system as the local north interface and the low level north interface; transmission management module, used to transmit the low level north interface to the north interface unit in the low level network management system. The described local network management north interface is the network level interface, and the lower network management north interface is the net element level interface. This invention addresses the problem of the inconsistencies in all the north interfaces in the upper and lower network management system in existing technology, and reduces the work of system researching and maintaining, so the user's actual need can be better satisfied.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multi-level network management system and a northbound interface processing method in the multi-level network management system. Background technique [0002] With the continuous development of network technology, the application and scale of the network continue to expand, and the information that the network management system needs to maintain is also increasing. The network management system is mainly for monitoring, configuration and fault diagnosis of network equipment. The main functions include automatic topology discovery, remote configuration, performance parameter monitoring and fault diagnosis, and the interface should be opened to external network management (such as upper-level network management, network management software of third-party manufacturers), so that external network management can obtain the network management system through this interfa...

Problems solved by technology

[0004] However, the current network scale is very large, there are multi-level network management systems in the network, and the network management systems of different layers all have their own developed northbound interface units, so that the northbound interface units of the existing multi-level network management systems mainly have the defect of poor consistency , the main performance is as follows:

[0005] First of all, the northbound interface units of different layers of network management systems may be developed by different manufacturers and different software developers, which makes it difficult for the interface standards adopted by the northbound interface units of different layers of network management systems to be consistent, so that the northbound interface units of multi-level network management systems poor consistency among

[0006] Furthermore, even if the network management systems of different layers provide northbound interface units according to the same standard, in the northbound interface units of the network management systems of different layers, developers can change the expression form (or object name) defined by the same object in the network according to their own preferences. ) inconsistency, resulting in inconsistencies in the information of the same object returned by different layers of network management systems, and the disadvantage of consistent information content, it is difficult to meet user needs

For example, both SNMS and EMS provide northbound interface units in accordance with the TMF8.14 2.0 standard. When SNMS and EMS receive a service request from an external network In the respective northbound interface units, the object names defined for the boards are inconsistent. As a result, in the request information returned by SNMS and EMS to the external network management, the object names of the detailed board information are inconsistent, but the content of the information is consistent. The network increases the complexity of processing information, and it is also difficult to meet the needs of users to provide unified northbound interface units for different layers of network management systems;

[0007] In addition, since network management systems at different layers focus on different services in the network and pay attention to information in the network, it is difficult to ensure that the northbound interface units of network management systems at different layers are completely unified.

For example, SNMS focuses on the management of end-to-end services, while EMS focuses more on the management of single-station services. Therefore, even if SNMS and EMS provide northbound interfaces in accordance with the TMF8.14 2.0 standard, when the external network management queries the When requesting service for all board information, it is actually difficult for SNMS and EMS to ensure that the detailed data of all board information under the same network element is consistent in the returned request information

[0008] In addition, the network management systems of different layers need to independently maintain and develop northbound interface units. For example, both SNMS and EMS provide northbound interfaces in accordance with the TMF8.14 2.0 standard. Therefore, SNMS needs to develop the query interface in the northbound interface unit according to its own inventory management, and EMS also needs it. Therefore, developing and maintaining northbound interface units of different layers of network management systems requires huge manpower, material and financial resources. Increase the operating cost of the network
