A GateKeeper-based NAT traversal method for media transport in H.323 network system
H.323 has application to a variety of network media, including local area networks, enterprise networks, Internet and wireless networks. But NAT (Network Address Translation) traversal problem is baffling H.323 communication due to complex network situations and flaws of protocol. The existing traversal methods are not suitable for all network situations. They often require upgrading or adding other deceives and protocols to support call procedure. In this paper, A NAT traversal method based on GateKeeper (GK) for media transport is proposed. This scheme only needs a GateKeeper Server, which is able to route call. This resolving method is also very easy to implement without changing network situations. And it is very available for communications with many NAT deceives in applications. The mechanism may be used asthe short -term solution for the NAT traversal problem in H.323 system.
