Method and device for obtaining routing information of electro-optical multi-layer network

摘要

The present disclosure provides a method and device for obtaining the routing information of an electro-optical multi-layer network. The ports on which an optical transmitter and an optical receiver are located are determined, and the electro-optical conversion information is added to the routing information on a port of the optical layer node side or the electro layer node side on which the optical transmitter and the optical receiver are located. The electro-optical conversion information includes but is not limited to the wavelength tuning capability and signal processing capability. Through the extending of the current Multi-Layer Network (MLN) information model and Wavelength Switched Optical Network (WSON) information model, the present disclosure describes the routing information including the electro-optical conversion information of the present disclosure more accurately, and perfects the electro-optical multi-layer network information model, and improves the accuracy of the path calculation to reach the optimization.
