Patent ID: 8144620

Claim:
A method for implementing a network connection service, comprising: initiating a request for establishing a network connection service between a source user node and a destination user nodded, wherein the request is initiated from the source user node to a network ingress node; parsing, by the network ingress node, the request, and querying a directory server according to a parsing result to obtain a set of connection and adaptation modes of a network egress node, which support the network connection service; obtaining, by the network ingress node, a set of connection and adaptation modes of the network ingress node, which support the network connection service, based on a locally stored value or by querying the directory server; intersecting, by the network ingress node, two obtained sets to obtain a new set of connection and adaptation modes supported by both of the network ingress node and the network egress node, and selecting one from the new set as a connection and adaptation mode of the network connection service; registering, by the network ingress node, with the directory server selected connection and adaptation mode which supports the network connection service; and establishing a network connection and performing an adaptation configuration according to the connection and adaptation mode to implement the network connection service.
