Embodiment Construction

[0079] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0080] Such as figure 1 As shown, the present invention discloses a comprehensive and rapid WSON network planning solution verification method, comprising the following steps:

[0081] Step 1, obtain the WSON network planning scheme, figure 2 It is the verification network topology diagram of the present invention, and whether the recovery route provided by the verification planning scheme includes the possibility of fiber breakage in all service links;

[0082] Step 2, verify whether the recovery route of the service and the original working route of the service share the shared risk link group in the fault segment;

[0083] Step 3, verify whether the working route of the associated business is separated, including the shared risk link group;

[0084] Step 4, verify whether the recovery route of the associated service group A is separated from the ...

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...
