Abstract
A method and apparatus for performing tunneling signaling over an IP tunneling path connected to an end-to-end path on an IP network are provided, in which an end-to-end signaling flow is received from a sender or a receiver on the end-to-end path, a tunnel signaling flow is generated corresponding to the received end-to-end signaling flow, and the generated tunnel signaling flow is transmitted through the IP tunneling path, the end-to-end signaling flow is forwarded between an entry node and an exit node of the IP tunneling path, and the forwarded end-to-end signaling flow is transmitted to at least any one node on the end-to-end path, wherein the forwarding is simultaneously performed with the transmitting of the tunnel signaling flow, and the transmitting of the end-to-end signaling flow is suspended until the transmitting of the tunnel signaling flow is completed.
