Abstract

Simultaneous transmission and reception of voice, data and video to and from an end - point of a IP network is facilitated by the use of HTTP (hypertext transfer protocol). A first end - point forms two HTTP connections with a HTTP tunneling server. A second end - point of the same network forms also two HTTP connections with the same tunneling server. Videoconferencing protocols, notably SIP and H.323 are tunneled though the HTTP connections to form a full - duplex connection unhindered by firewalls, NAT and PAT processes or by HTTP proxies.
