Method for obtaining network information and network management system

Abstract

This invention provides one method to acquire network information, which comprises the following steps: first network sends preset protector sub network information index orders; second management receives the said order and requires protection sub network relative information and sends required information to first network management. The invention provides one network management system composed of first and second managements. Through above method and system, it is helpful to get whole network information and whole management.

Description

technical field [0001] The invention relates to the field of optical technology communication, in particular to a method for acquiring network information and a network management system. Background technique [0002] Optical fiber communication systems are widely used due to their huge bandwidth and resources and relatively low manufacturing costs. At present, the optical fiber transmission network has become the leading transmission network in all countries in the world. However, the high-level network management of the existing optical transport network generally only manages the network elements in the protection field, and does not involve the management of the network layer. In order to meet the unified management of the optical transport network of telecom operators and the interoperability requirements of the optical transport network management of various equipment manufacturers, the optical transport network EML (Element Management System, network element manageme...

Problems solved by technology

[0004] At present, the proposal issued by TMF (TeleManagement Forum, Telecommunications Management Forum) establishes the management of the protection group on a single network element, but this protection group is still established on the basis of a single network element. Other protection groups in the same protection subnet are not related to each other. When the high-level network management manages, it can only obtain the information of this individual protection group, but cannot know the information of other protection groups that work together with this protection group.

When there is a problem with a certain protected service, when the protection group initiates a protection service request to other network elements, it is possible that other network elements have not established a service protection group, or the information of the established protection group does not correspond. The created protection group cannot guarantee that the service is truly protected; the high-level network management cannot obtain complete information of the entire network, nor can it effectively manage the entire network

[0005] To sum up, although the existing technology can also manage the network, the high-level network management cannot completely obtain the information of the entire protection network, and the business cannot be truly and effectively protected. Therefore, the high-level network management cannot effectively and comprehensively manage the entire network. management
