Transport slice identifier for end-to-end 5g network slicing mapping

A method of identifying network slices in a transport network by a transport network device, comprising:

• receiving, from a controller, a first slice creation request to create a network slice, the first slice creation request comprising a global identifier corresponding to the network slice;
• searching a transport slice mapping database for at least one mapping entry corresponding to the global identifier;
• generating, based on determining that the at least one mapping entry was not found, a first transport slice identifier corresponding to the network slice;
• adding a first mapping entry to the transport slice mapping database indicating a first relationship between the global identifier and the first transport slice identifier;
• adding a second mapping entry to a transport slice path mapping database indicating a second relationship between the first transport slice identifier and a first network path identifier of a first network path assigned to the network slice;
• and
• publishing, to a performance monitoring system (PMS), the first mapping entry and the second mapping entry.

A non-transitory computer-readable storage medium having recorded thereon a program for identifying network slices in a transport network by an apparatus, the program comprising operations to:

• receive, from a controller, a first slice creation request to create a network slice, the first slice creation request comprising a global identifier corresponding to the network slice;
• search a transport slice mapping database for at least one mapping entry corresponding to the global identifier;
• generate, based on a determination that the at least one mapping entry was not found, a first transport slice identifier corresponding to the network slice;
• add a first mapping entry to the transport slice mapping database indicating a first relationship between the global identifier and the first transport slice identifier;
• add a second mapping entry to a transport slice path mapping database indicating a second relationship between the first transport slice identifier and a first network path identifier of a first network path assigned to the network slice;
• and
• publish, to a performance monitoring system (PMS), the first mapping entry and the second mapping entry.
