    摘要： The disclosure 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 disclosure 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.

    摘要翻译： 本公开公开了一种用于有状态路径计算元件（PCE）和有状态PCE的处理方法。 该方法包括：有状态PCE完成有状态PCE的路径计算，并保留或锁定计算路径所需的资源; 有状态PCE接收第一通知消息，其中第一通知消息用于在资源预留协议（RSVP）信令过程或在RSVP信令过程中被成功删除的路径中通知状态PCE中未成功建立的路径 ; 并且有状态PCE释放由第一通知消息通知的路径所需的资源。 本文提出了有状态PCE认识到的资源信息的实时性和准确性以及PCE路径计算的准确性，从而避免资源冲突。
