Abstract
Systems and methods include receiving a request for a service in a Segment Routing network; determining an intended path for the service, provisioning a head-end node with a Segment Identifier (SID) list for the intended path, and reserving bandwidth for the service on the intended path; monitoring the Segment Routing network; and responsive to a condition determined based on the monitoring, updating the SID list for the service. The condition can include a current path for the service in the Segment Routing network differing from a provisioned path in the Segment Routing network. The condition can be based on any of a failure in the Segment Routing network, a topology change in the Segment Routing network, bandwidth changes in the Segment Routing network, an optimization timer, and input from an operator.
