Abstract

The invention discloses a system and a method for WDM (wavelength division multiplexing) network topological structure vectorization and relates to WDM network planning systems. The system comprises a data collection module, a graph model module, a coordinate calculating module and a graph leading-out module. The method includes collecting WDM network topology original data, calculating position coordinates of each node, optical cable connection starting from the nodes and anchor points of service channels, calculating coordinates of the optical cable connection and service channel connection, setting content of text messages of node equipment, the optical cable connection and the service channel connection and position coordinates of text message display, expressing nodes of WDM network topology by using XML (extensible markup language) format elements in SVG (scalable vector graphics) according to data acquired by calculation, setting the optical cable connection to Path elements in the topology, setting service connection to Line elements in the WDM network topology, and displaying all text descriptions in the network topology by using text object elements. By the system and the method for WDM network topological structure vectorization, network topological structure vectorization of a WDM network can be realized, a vector graph can be formed, and incremental modification on the graph can be realized.

Description

technical field [0001] The present invention relates to a WDM (DenseWavelengthDivisionMultiplexing, Dense Wavelength Division Multiplexing) network planning system, specifically a system and method for WDM network topology vectorization. Background technique [0002] With the continuous development and mature application of optical transmission technology, optical transmission network has also developed at an unprecedented high speed. At present, the core technology of the optical transmission network has been transformed from the traditional SDH (Synchronous Digital Hierarchy, Synchronous Digital System) technology to the hybrid technology of SDH and WDM (DenseWavelengthDivisionMultiplexing, Dense Wavelength Division Multiplexing), and is gradually evolving to the next-generation optical network. . Due to the complexity and size of the current optical transmission network, the utilization rate of the network is not high, which is not conducive to the rapid deployment of ne...

Problems solved by technology

However, the general network planning system cannot support the export of network topology, or can only export the network topology as graphic files in JPG and other formats. This graphic file cannot be vectorized, and does not support incremental modification on graphics, nor It is convenient for project bidding, communication, etc.
