Abstract
Systems and methods of capacity changes in an optical network having a plurality of optical sections include, responsive to a request for a capacity change for a plurality of channels, bundling the plurality of channels into different steps such that all of the plurality of channels are assigned to a step of the different steps; and causing implementation of the different steps across the plurality of optical sections, wherein each section performs the implementation and the bundling between corresponding Optical Add/Drop Multiplexer (OADM) nodes independently and asynchronously from one another.
Claims15
A method of capacity changes in an optical network having a plurality of optical sections, the method comprising:
- responsive to a request for a capacity change for a plurality of channels, bundling the plurality of channels into different steps such that all of the plurality of channels are assigned to a step of the different steps;
- and
- implementing the different steps across the plurality of optical sections, wherein each section performs the implementation and the bundling between corresponding Optical Add/Drop Multiplexer (OADM) nodes independently and asynchronously from one another,
- wherein one of
- each section performs the implementing and the bundling without any communication or notification from upstream controllers to sequence channel actions, or
- each section performs the implementing asynchronously from other sections meaning a given channel of the plurality of channels that traverses multiple optical sections does not need to be in a same step or do the different steps need to be coordinated in time.
A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more controllers, associated with an optical network having a plurality of optical sections, to perform steps of:
- responsive to a request for a capacity change for a plurality of channels, bundling the plurality of channels into different steps such that all of the plurality of channels are assigned to a step of the different steps;
- and
- causing implementation of the different steps across the plurality of optical sections, wherein each section performs the implementation and the bundling between corresponding Optical Add/Drop Multiplexer (OADM) nodes independently and asynchronously from one another,
- wherein one of
- each section performs the implementation and the bundling without any communication or notification from upstream controllers to sequence channel action, or
- each section performs the implementation asynchronously from other sections meaning a given channel of the plurality of channels that traverses multiple optical sections does not need to be in a same step or do the different steps need to be coordinated in time.
A system comprising:
- one or more controllers, each associated with an optical section of a plurality of optical sections in an optical network, each controller is configured to, for a given optical section,
- responsive to a request for a capacity change for a plurality of channels, bundle the plurality of channels into different steps such that all of the plurality of channels are assigned to a step of the different steps;
- and
- causing implementation of the different steps across the given optical section,
- wherein each of the one or more controllers performs the implementation and the bundle of the plurality of channels between corresponding Optical Add/Drop Multiplexer (OADM) nodes of the given optical section independently and asynchronously from other controllers,
- wherein each of the one or more controllers performs the implementation and the bundle of the plurality of channels without any communication or notification from upstream controllers to sequence channel actions.
