Link API creates the binding between SDP nodes and router ports. Link API is invoked:

• initially for all existing nodes

• for every new node added to the network

The IETF NBI is invoked:

• for every new slice request

• for every slice modification

The IETF NBI is also used to provide status updates, alarms, and other information from nodes to the TSC.

Tutorials for the Transport Slice Controller API are available on the Network Developer Portal .
