Method and device for optimizing transmission network route based on neural network model

Abstract

The invention provides a method and a device for optimizing a transmission network route based on a neural network model and belongs to the technical field of network security. The method comprises the following steps: 1) converting a transmission network into a routing map of the transmission network supported by a pulse coupling neural network model; 2) performing same routing analysis and performing link replacement on a same routing link in the routing map of the transmission network; and 3) after finishing the link replacement, calculating the transmission network route after being optimized on the obtained routing map of the transmission network, thereby being capable of efficiently preventing same route hidden danger in the transmission network.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method and a device for optimizing transmission network routing based on a neural network model. Background technique [0002] As the underlying transmission network of communication signals, the transmission network is the foundation of the communication network. With the development of multi-service integration, voice, data, image, multimedia, IP services, and various value-added services and intelligent services are carried on the transport network. The network security of the transport network is becoming more and more important. [0003] In recent years, various transport network technologies emerge in an endless stream, such as PDH (Pseudo-Synchronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy), WDM (Wavelength Division Multiplexing), PTN (Packet Transport Network) packet transport network, etc., although these technologies also provide V...

[0003] In recent years, various transport network technologies emerge in an endless stream, such as PDH (Pseudo-Synchronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy), WDM (Wavelength Division Multiplexing), PTN (Packet Transport Network) packet transport network, etc., although these technologies also provide Various network protection schemes based on the second and third layers of OSI (Open Systems Interconnection), such as 1+1 protection switching, 1:1 protection switching, 1:N Protection switching, channel / optical channel protection, and multiplex section protection in ring networking, based on the network layer, there are LSP (Layered Service Provider) routing protection switching technology, MPLS (Multi-Protocol Label Switching) fast rerouting technology, etc., but Since the physical layer must be carried by the optical cable, it is often limited by the deployment of the optical cable and the carrier of the optical cable in the real world - the pipeline pole, which leads to the failure of the upper layer protection scheme and causes various network security risks.

[0004] A typical example of the failure of the upper layer protection scheme due to the hidden danger of the physical routing of the optical cable is that in the SDH / WDM ring network, the optical fibers in the two directions of the ring node are carried in the same optical cable, or the optical cables where the two optical fibers of the ring node are located are in the same pipe. bearer, leading to the risk of the same routing
