Methods and apparatus for managing network traffic using network address translation

A method manages network traffic using NAT in a data communications device having a NAT data structure (e.g., a NAT table). The method includes the step of creating, in the NAT data structure, a first entry to coordinate a first data flow from a server to a client (e.g., a video channel or an audio...

description A method manages network traffic using NAT in a data communications device having a NAT data structure (e.g., a NAT table). The method includes the step of creating, in the NAT data structure, a first entry to coordinate a first data flow from a server to a client (e.g., a video channel or an audio channel of an RTSP session), and concurrently creating a second entry to coordinate a second data flow from the client to the server (e.g., a video control channel or an audio control channel of the RTSP session). The method further includes the steps of conveying a data element (e.g., a UDP packet) of the first data flow from the server to the client based on the first entry, and conveying a data element of the second data flow from the client to the server based on the second entry.
