| Abstract: | The traversing of the media and video streams across NAT/Firewall has been the greatest obstacle in the development of NGN service. Being a practical way of NAT/firewall traversing, Full Proxy shows its expansibility. In the first place of this paper we analyze the theory of Full Proxy and the call flow based on the Full Proxy. In the end, we realize a Full Proxy on an embedding system with two-cpus. |
