Abstract: According to the problems in the present NAT schemes, an NAT traversal in accordance to SBC-based SIP protocol is proposed, which is implemented by relaying simultaneously both the SIP signaling messages and RTP media streams. With the system architecture of SBC illustrated, the NAT traversal process is analyzed in detail under different applications. The results of functional analysis and performance test showed that the proposed NAT traversal in comparison with other conventional schemes is available to implement transparent traversal with no change required for network configuration and improved efficiency provided.
