Patent ID: 7984185

Claim:
A method for establishing a network connection service, comprising: initiating to a network ingress node a request for establishing the network connection service from a user side of a source end to a user side of a sink end; negotiating, between the network ingress node and a network egress node through message exchange at a control plane, to determine a network connection between the two nodes and a protocol adaptation stack from the user side of the source end to a network side of the source end and from the user side of the sink end to a network side of the sink end, for supporting the network connection service; and establishing, from the network ingress node to the network egress node, the network connection and configuring the adaptation stack at the network ingress and egress nodes, so as to establish the requested network connection service; wherein negotiating between the network ingress node and the network egress node through the message exchange at the control plane comprises: sending a connection request message from the network ingress node to the network egress node, said connection request message carrying information of the network connection types and the protocol adaptation stacks supported by the network ingress node; determining, by the network egress node, a network connection type and a protocol adaptation stack supported by the both nodes according to the information carried in the connection request message and the information of the network connection types and the protocol adaptation stacks supported by the network egress node itself; and returning, from the network egress node to the network ingress node, a connection response message, said connection response message carrying information of the network connection type and the protocol adaptation stack supported by the both nodes, so as to accomplish the negotiation.
