Many Internet hosts - such as PCs - while capable of running multicast applications, cannot access the MBone (or other wide-area multicast network) because the router(s) that connect them to the Internet do not yet support IP multicast routing. The 'UDP Multicast Tunneling Protocol' (UMTP) enables such a host to establish an 'ad hoc' connection to the MBone by tunneling multicast UDP datagrams inside unicast UDP datagrams. By using UDP, this tunneling can be implemented as a 'user level' application, without requiring changes to the host's operating system.
