A multi-purpose avionics relay network topology configuration management method and system

Abstract

The invention discloses a multipurpose avionics relay network topology configuration management method and a multipurpose avionics relay network topology configuration management system, wherein the method includes the following steps: the configuration information of all network device fibre-optic links in a network is transmitted by a server; after receiving the configuration information, each network device obtains respective configuration information of the fibre-optic link, obtains and transmits the identity information of the opposite devices and the port number information of the connected opposite devices to the server at the same time, and then transmits the configuration information of all the network device fibre-optic links to the other network devices. By means of the invention, network authentication can be conveniently carried out, consequently, the consistency between actual network topological relation and an expected network topology structure can be guaranteed or the difference between the actual network topological relation and the expected network topology structure can be known and adjusted. Because the configuration of the network topology can be directly viewed and edited, the configuration of the network topology can be efficiently managed.

Description

technical field [0001] The invention relates to an optical fiber transmission network and an optical fiber relay system, in particular to a configuration management method for a multipurpose avionics relay system (MARS, Multipurpose Avionics Relay System). Background technique [0002] Before the optical fiber network equipment enters the normal working state, its optical port configuration and time slot switching configuration need to be correctly configured on the host computer and downloaded to the device. [0003] In the existing optical fiber transmission network, the configuration of each network device itself rather than the entire network is expressed in a private data format. The data expressing the configuration of each network device is also called network element description data. For example, it is described that a certain optical transceiver has three optical ports. In order to meet the service requirements, it is necessary to configure the ninth time slot of ...

Problems solved by technology

In other words, the correctness of the entire network connection can only be guaranteed by actual engineering connections and manual business tests

[0006] In addition, the host computer can only be used to individually configure the time slots for the ports of the network devices one by one. If the configuration error causes data failure, the time slot switching configuration can only be manually checked for the network devices one by one. Can only be guaranteed by manual business testing

[0007] 2) The network device receives the management information from the upper computer, and can only broadcast to other devices through all other optical ports except the receiving port

[0008] As a result, each network device can only obtain its own information, but not the overall information of the system, making the network device look like a lonely blind and deaf

[0009] 3) The private data format is generated by the host computer software for internal use of the system, and cannot be directly viewed or edited

[0011] However, the above-mentioned existing systems have not yet provided a good solution for configuration management of the network topology
