Method, device and system for presenting network topology

Abstract

The invention discloses a network topology presentation method, device and system. The presentation method includes: collecting the multiplex section protection information of the transmission multiplex section in the network element management system; restoring the multiplex section ring logic topology of the transmission multiplex section through the multiplex section protection information; collecting the multiplex section ring topology in the network element management system Specify the network element name and network element port number of each transmission network element on the transmission path of the service; based on the collected multiplex section protection information, the network element name and network element port number of each transmission network element, the multiplex section ring The logical topology is superimposed on the transmission path to present the MSP protection information on the transmission path. According to the network topology presentation method, device and system provided by the embodiments of the present invention, the multiplex section protection information is topologically superimposed on the transmission path, so that the service-based transmission path topology diagram can present the multiplex section protection information of the optical cable.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method, device and system for presenting network topology. Background technique [0002] With the maturity of synchronous digital transmission technology and the continuous expansion of services carried by the network, the security requirements for the backbone transmission network are also getting higher and higher. In order to ensure the reliability of the network and realize effective protection at the connection point of the ring network, the multiplex section protection (Multiplex Section Protection, MSP) technology has been widely used due to its short service interruption time, shareable protection channel, and high network capacity. It plays a pivotal role in the safe operation of the entire network. [0003] The transmission network is a topology-based network. The service-based transmission path topology map can realize the end-to-end presentation of topology-based ...

Problems solved by technology

[0004] However, when building a service-based transmission path topology map, the transmission path topology of a specified service is drawn by collecting the associated information of the transmission ports configured on the transmission network element. Due to the method and process of constructing a service-based transmission path topology map, Since the multiplex section protection information achieved through protocol protection cannot be collected, the transmission path topology map cannot be combined with the multiplex section protection information, resulting in the inability to realize the multiplex section protection that presents a certain section of optical cable on the transmission optical path Due to the situation, the protection information of the transmission optical path related to the service in the network management system is incomplete.
