Abstract
Official abstract text for this publication.
The present invention relates to communications technologies and discloses a tunnel management method, a tunnel management apparatus, and a communications system so that a node that causes failure of a tunnel management request can be determined. According to the present invention, a response returned by a tunnel management node to an initiating node includes not only a cause value of tunnel management request failure but also information of the node that causes failure of the tunnel management request, so that the initiating node can find the node that causes failure of the tunnel management request and determine the error checking direction. The present invention is applicable to network devices in a communications network.
First claim
Opening claim text (preview).
What is claimed is: 1. A tunnel management method, comprising: receiving, by a tunnel management node, a tunnel management request from an initiating node; after receiving the tunnel management request, sending, by the tunnel management node, the tunnel management request to a remote node; receiving, by the tunnel management node, a response message from the remote node responsive to the tunnel management request, wherein the response message comprises a cause value indicating…
