Title:
WAVEBAND SWITCHING METHOD BASED ON DISTANCE ADAPTATION
Document Type and Number:
WIPO Patent Application WO/2020/061790
Kind Code:
A1
Abstract:
A waveband switching method based on distance adaptation, comprising: S1. constructing a waveband switching elastic optical network; S2. finding the waveband path in the waveband switching elastic optical network that can adapt to the most given requests; S3. selecting a corresponding modulation format for the adapted given request and allocating a corresponding spectrum resource; S4. repeating steps S1-S3 until all the given requests are allocated to corresponding spectrum resources. The implementation of the waveband switching method based on distance adaptation of the present invention can meet the minimum number of established waveband paths for wavelength service requests, so that the number of network ports for optical network service switching is as small as possible.
