摘要
The present invention discloses a processing method for a stateful Path Computation Element (PCE) and a stateful PCE. The method includes: the stateful PCE completes path computation of the stateful PCE, and reserves or locks resources needed by a computed path; the stateful PCE receives a first notification message, wherein the first notification message is used for notifying the stateful PCE of a path which is unsuccessfully established during a Resource Reservation Protocol (RSVP) signalling procedure or a path which is successfully deleted during an RSVP signalling procedure; and the stateful PCE releases resources needed by the path notified by the first notification message. The present invention improves the real-time property and accuracy of the resource information which the stateful PCE is aware of, and the accuracy of the path computation of the PCE, so as to avoid resource conflict.
