Dual-redundancy FC-AE-1553 network reconstruction method based on switched topology

Abstract

The invention provides a dual-redundancy FC-AE-1553 network reconstruction method based on switching topology, which comprises the following steps: in a network in which a network communication node adopts a redundant backup design and a node transmission channel is a dual-redundancy channel, adding a network fault detection mechanism and a main / standby node communication function switching mechanism; after the network controller or the network end node breaks down, switching the backup network end node to the network controller, uploading a network message scheduling table, completing networkcommand frame organization scheduling and network management control, and taking over the communication function of the broken-down network controller; or switching to the network end node, and switching the physical mapping relationship between the address of the network end node and the switching port by the network switch, so as to take over the function of the fault end node and complete thenetwork message communication function. According to the method, the reconstruction problem of the switched FC-AE-1553 network is solved, the reconstruction time is shortened, and the network reliability is improved.

Description

technical field [0001] The invention relates to the field of network reconfiguration design, in particular to a method for reconfiguring a high-speed optical fiber communication network, which adopts the FC-AE-1553 protocol for data communication. Background technique [0002] The FC-AE-1553 network is a high-speed optical fiber communication network that adopts a command-response communication mechanism and supports a switched network topology. The system is usually composed of a network controller, a network switch, and a network end node. The network communicates with the network through the network controller. Messages are centrally controlled and dispatched. In order to improve the reliability of the network system, the network nodes adopt dual redundant transmission channels, and a 1+1 redundant backup design is carried out for the network controller and key end nodes. During network operation, when the network controller or network end node fails, the backup network ...

AI Technical Summary

Problems solved by technology

Due to the access of backup nodes and the switching of network functions, the network function structure, communication links and routing relationships will change, and the network communication configuration needs to be adjusted dynamically, while the FC-AE-1553 network combines a command-response centralized control mechanism, Due to the characteristics of dual redundant transmission channels and switched network topology, the general network reconfiguration method cannot realize the reconfiguration of the FC-AE-1553 network
