Verification method for WSON network planning scheme

Abstract

The invention discloses a verification method for a WSON network planning scheme, and the method comprises the steps: 1, verifying whether a restoration route provided by a planning scheme has the fiber breaking possibility in all business links or not; 2, verifying whether the restoration route of the business and an original working route of the business share a shared risk link group at a fault segment or not; 3, verifying whether the working routes of the correlated business groups are separated or not; 4, verifying whether the restoration route of the correlated business group A and the restoration route of the correlated business group B are separated or not; 5, verifying whether the wavelengths of working wave channels of all business links are reused or not; 6, verifying whether the wavelength of the restoration route is reused under the fiber breaking condition of each link or not; 7, verifying whether the wavelength of the restoration route and the wavelength of the working route are reused or not; 8, verifying the OSNR performance of a system; 9, verifying whether the number of downlink modules at an ROADM node configured in the planning scheme meets the demands or not.

Description

technical field [0001] The invention relates to a method for verifying a WSON network planning scheme, in particular to a planning scheme for a large and medium-sized MESH network that has enabled the WSON dynamic rerouting function and is capable of resisting one fiber cut and recovering 100%. Background technique [0002] ROADM (Reconfigurable Optical Add-Drop Multiplexer, Reconfigurable Optical Add-Drop Multiplexer) technology has basically matured after years of development, and its equipment forms include wavelength-related direction-related (optical distribution frame form), wavelength-related direction-independent (D / Directionless), wavelength-independent direction-correlation (C / Colorless), wavelength-independent direction-independent (CD, Colorless and Directionless) and wavelength-independent direction-independent competition-independent (CDC, Colorless, Directionless and Contentionless), etc. In recent years, domestic operators have begun to apply ROADM technolog...

Problems solved by technology

[0004] Purpose of the invention: The technical problem to be solved by the present invention is to provide a comprehensive and fast WSON network planning solution verification method for the WSON network planning solution output by WSON network planning software, which is complex and huge and cannot be manually verified, which is suitable for Planning scheme for large and medium-sized MESH networks with dynamic rerouting function, anti-fiber breakage and 100% recovery

After the verification method is implemented by software, it can comprehensively and quickly evaluate and test the scheme, and solves the problem that the WSON network planning scheme cannot be verified manually, and has strong technical and practicability
