The invention discloses a protection subnet risk assessment method for an optical transmission network. The protection subnet risk assessment method comprises the following steps: S1, acquiring configuration information of each device, wherein the configuration information comprises ID and name of the device, optical path relation between devices, configured protection subnet name, configured protection subnet type and coordinate information of the device in topology; in the invention, network-level path protection evaluation is carried out for the whole optical transmission network, analysis and presentation of equipment nodes without protection subnets, a single-chain protection subnet, a large-ring protection subnet and a single-node protection subnet are provided, and positions and relationships of all nodes are presented in a topological graph according to coordinates of the equipment nodes. Meanwhile, the stacking information of each protection subnet is drawn according to the contour of the relation between the equipment nodes and the equipment, and finally optimization suggestions are output, so that network planners are supported to master the protection subnet risk conditions of the whole network and visually browse the protection subnet risk conditions.
Description
Technical field [0001] The present invention relates to the technical field of optical transmission networks, in particular to a protective subnet risk assessment method of optical transmission networks. Background [0002] Optical transmission system, in order to improve the reliability of services on the link, usually on the basis of the working link, the need to increase the protection link, when the working link is invalid or the performance is inferior to a certain necessary level will be replaced by the protection link, with the development of the network, network planning will become complex, easy to exist risks, the current optical transmission network equipment network management system to provide protection subnet interface configuration management capabilities, support to view the destination of each device node configuration of each protection subnet information, support to view the type of each protection subnet, Device node information, which supports the presentat...
