Inter-node connection method and apparatus

Abstract

An inter-node connection method and apparatus for at least a first and second nodes respectively connected to private IP address network ends of at least a first and second address translation devices, which translate a private IP address into a global IP address, through global IP address network ends of the first and second address translation devices. Firstly, a control session is established with the first or the second node respectively through the first or the second address translation device; and secondly a connection request frame or a connection reply frame is respectively transferred to the second or the first node by the control session through the second or the first address translation device when the connection request frame or the connection reply frame is received respectively from the first and second nodes by a data session. The second or the first node transmits a data frame toward the first or the second address translation device, which binds an IP address and a port number of the first or the second node included in the data frame respectively to those of the second or the first address translation device for a direct communication between the nodes.
