1. An audio- or video-conferencing transport system, comprising:
- a transport network, comprising multiple points of presence, connected by guaranteed bandwidth channels;
a media transport relay in the transport network;
a control server configured to provide admission control to the transport network;
a first Internet Service Provider (ISP) network, connected to the transport network;
a second ISP network, connected to the transport network;
a first audio- or video-conferencing terminal, connected to the first ISP network; and
a second audio- or video-conferencing terminal, connected to the second ISP network;
wherein the first audio- or video-conferencing terminal is configured to send real-time audio or video data to the second audio- or video-conferencing terminal by addressing the real-time audio or video data to the media transport relay in the transport network, so as to cause the real-time audio or video data (i) to travel from the first audio- or video-conferencing terminal to the transport network via the first ISP network, and then (ii) when admitted by the control server, to travel through the transport network over a guaranteed bandwidth channel of the guaranteed bandwidth channels, and then (iii) to travel from the transport network to the second audio- or video-conferencing terminal via the second ISP network.

Abstract
A system and method of operating equipment and services to allow enhanced global transport of IP packets is presented. A global virtual network with guaranteed capacity is used to transport said IP packets. A number of application-specific forwarding devices are deployed to detect and forward selected traffic types to the virtual network. The application-specific selective forwarding devices can be implemented based on the IP packets analysis, or by deploying enhanced control protocols like SIP/H.323.
