| 摘要 |
Embodiments of the present invention provide a method and an apparatus for processing residual information. The method includes: receiving first information, sent by a first path computation client PCC, about a first label switched path LSP, and determining, according to the first information, information about a resource occupied by the first LSP; obtaining a resource deletion situation corresponding to the first LSP after receiving second information, sent by the first PCC, about the first LSP, where the second information is used to indicate that the first LSP needs to be deleted or the first LSP needs to be degraded; and when it is determined that the first LSP has residual information according to the information about the resource occupied by the first LSP and the resource deletion situation corresponding to the first LSP, sending a notification message to a path computation client PCC having the residual information on the first LSP, where the notification message is used to indicate deletion or degradation of the first LSP. The method and apparatus for processing residual information in the embodiments of the present invention improve accuracy and efficiency for detecting residual information, thereby highly simplifying detection and clearing of residual information on an entire network. |
