Elegant Temporal Label Switched Path Tunnel Service Controller

A network controller implemented in a network, comprising:

• a receiver configured to receive a request for creating a temporal label switched path (LSP) in a scheduled time interval;
• a processor coupled to the receiver and configured to:
• compute a shortest path in a network satisfying a constraint for the temporal LSP in the scheduled time interval;
• reserve, in a temporal traffic engineering database (T-TED) of the network controller, resources on each link the LSP traverses for the scheduled time interval;
• and
• initiate, at a beginning of the scheduled time interval, setup of the LSP in the network through sending a LSP creation request to a path computation client (PCC) on an ingress node of the LSP.

A network controller, comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions, which when executed, cause the processor to be configured to:
• receive a request for creating a temporal label switched path (LSP) in a scheduled time interval;
• compute a shortest path in a network satisfying a constraint for the temporal LSP in the scheduled time interval;
• reserve, in a temporal traffic engineering database (T-TED) of the network controller, resources on each link the LSP traverses for the scheduled time interval;
• and
• initiate, at a beginning of the scheduled time interval, setup of the LSP in the network through sending a LSP creation request to a path computation client (PCC) on an ingress node of the LSP.
