Abstract
Disclosed are an SDBANS controller and associated orchestration system configured to implement scalable transport network slicing in an XGS-PON. Accordingly, the orchestration system configures the SDBANS controller for different regions and maps TN NSSI ID information to an OLT port of an SD-CPON OLT. The OLT port is allocated by the SDBANS controller.
Claims20
In a software defined broadband access network slicing (SDBANS) controller, a method of establishing a transport network slice, comprising:
- receiving, from a transport domain slice orchestrator, a trigger for a transport slice request;
- generating, based on a geographical region associated with the transport slice request, an optical line termination (OLT) slice allocation to associate an OLT port of a software defined, disaggregated combo-passive optical networking (SD-CPON) OLT with the transport network slice;
- and
- providing to the transport slice domain orchestrator a response to the trigger, the response including information indicating the OLT slice allocation for the geographical region associated with the transport slice request.

A method, performed by a transport domain slice orchestrator, of orchestrating transport network slices, the method comprising:
- mapping each network slice service type to a unique transport network (TN) network slice subnet instance (NSSI) ID (TN NSSI ID) in a set of TN NSSI IDs;
- mapping one of the unique TN NSSI IDs in the set of TN NSSI IDs to a geographical region and a software defined, disaggregated combo-passive optical networking (SD-CPON) optical line termination (OLT);
- selecting from a set of software defined broadband access network slicing (SDBANS) controllers, a selected SDBANS controller for the geographical region in which a transport slice request has originated;
- and
- triggering the selected SDBANS controller with the transport slice request for causing the selected SDBANS controller to generate an OLT slice allocation to associate an OLT port of an SD-CPON OLT that is controlled by the selected SDBANS controller.
