Abstract
Adaptive bundling of capacity changes in an optical section includes, responsive to a request for a capacity change for a plurality of channels on an optical section, determining spectral loading of the optical section; determining a bundling of changes for the capacity change based on the spectral loading of the optical section; and performing the capacity change based on the bundling. The bundling includes a number of steps to achieve all of the capacity change and a maximum allowable amount of optical spectrum that can be changed in each step. The maximum allowable amount of optical spectrum that can be changed in each step can be adaptively determined based on the channel loading.
Claims20
A controller comprising:
- a processor;
- and
- memory including instructions executable by the processor that, in response to such execution, cause the processor to
- responsive to a request for a capacity change for a plurality of channels on an optical section, determine spectral loading of the optical section,
- determine a bundling of changes for the capacity change based on the spectral loading of the optical section, and
- cause the capacity change based on the bundling, wherein the capacity change includes addition of a traffic channel by switching away from a channel holder source, deletion of a traffic channel by switching to the channel holder source, switching from one traffic channel source to another traffic channel source, and a combination thereof.
A method comprising steps of:
- responsive to a request for a capacity change for a plurality of channels on an optical section, determining spectral loading of the optical section;
- determining a bundling of changes for the capacity change based on the spectral loading of the optical section;
- and
- performing the capacity change based on the bundling, wherein the capacity change includes addition of a traffic channel by switching away from a channel holder source, deletion of a traffic channel by switching to the channel holder source, and a combination thereof.
A controller comprising:
- a processor;
- and
- memory including instructions executable by the processor that, in response to such execution, cause the processor to
- responsive to a request for a capacity change for a plurality of channels on an optical section, determine spectral loading of the optical section, wherein the optical section includes a full fill loading condition of its optical spectrum that includes any of traffic channels, channel holders, and unoccupied spectrum,
- determine a bundling of changes for the capacity change based on the spectral loading of the optical section, and
- cause the capacity change based on the bundling.
