Title:
WDM OPTICAL NETWORK OPTIMIZATION METHOD BASED ON WAVEBAND SWITCHING
Document Type and Number:
WIPO Patent Application WO/2020/061791
Kind Code:
A1
Abstract:
A WDM optical network optimization method based on waveband switching, comprising: S1, establishing a waveband-switching elastic optical network; S2, marking a flag bit of a given request that has not been successfully allocated a resource as not successfully allocated; S3, for each network node in the waveband-switching elastic optical network, finding a waveband path for the greatest number of given requests able to be handled thereby; S4, for said requests, allocating a corresponding wavelength resource, and on the basis of the allocation result, modifying the flag bit of said requests; S5, repeating steps S1-S4 until the flag bits of all given requests are marked as successfully allocated. By means of implementing the present WDM optical network optimization method based on waveband switching, the minimum number of waveband paths for wavelength service requests can be established, allowing the quantity of network ports for optical network service switching to be as small as possible.
