1. A universal bridge system for a multimedia conferencing system, comprising:
- a first interface, configured to carry streams of transport frames according to a transport protocol, wherein the first interface is a network switch configured for multicast routing of transport frames;
a control module connected to the first interface, adapted toallocate stream identifiers for each stream of transport frames;
dynamically allocate resources of the universal bridge system to multimedia sessions; and
maintain a routing table associating input stream identifiers with output stream identifiers, wherein multicast routing is performed using the stream identifiers as multicast addresses;
a media relay processor, connected to the first interface and configured to receive compressed media received from a first media relay endpoint, to deliver one or more streams of packets toward a second media relay endpoint, to deliver streams of transport frames to the first interface, and to receive streams of transport frames from the first interface; and
a legacy processor, connected to the first interface, configured to receive compressed media received from a first legacy endpoint, to deliver one or more streams of packets toward second legacy endpoint, to deliver streams of transport frames to the first interface, and to receive streams of transport frames from the first interface.

Abstract
A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.
