Abstract
A method implemented by a network element (NE) configured as a temporal tunnel service (TTS) controller, comprising computing, via a processor of the NE, a path in a network for a temporal label switched path (LSP), wherein the path satisfies a constraint in a scheduled time interval comprising a predetermined start time and a predetermined end time, reserving, at a current time prior to the predetermined start time via the processor, a first network resource on a link along the path computed for the temporal LSP, wherein the first network resource is reserved for the temporal LSP to carry traffic in the scheduled time interval, and sending, at the predetermined start time via a transmitter of the NE, a LSP creation request to a node associated with the temporal LSP to request creation of the temporal LSP along the path in the network.
