Abstract
A method and apparatus are provided for delivering multicast media in a network in which at least some nodes do not support delivery of multicast packets. A RTSP SETUP request is sent to a streaming server to send multicast packets, encapsulated within unicast wrappers, to a gateway node in the network. The RTSP SETUP request includes details both of the multicast destination address, and of the unicast destination address of the gateway node, requiring an extension to the RTSP protocol as currently defined and enabling the media server to send multicast packets in a unicast tunnel dynamically.
