Abstract

A method of managing content delivery to a client device by way of a proxy and a multicast transmitter in a hybrid unicast/multicast content delivery system. A plurality of proxies are used to handle unicast GET requests for content segments from its associated client device. Those requests can be forwarded over unicast directly to a unicast content server before receiving the response over unicast and forwarding that to the client device over unicast. Alternatively, those GET requests can be forwarded to the multicast transmitter where they can trigger a multicast response for delivering the requested content segment on a multicast channel. The multicast transmitter can be configured to count the number of GET requests received for a segment and compare that to what the multicast transmitter needs, and send an indicator, such as a probability or range of delay values, based on that comparison to the proxies. This indicator is then used by proxies to determine when and how to transmit a GET request for a subsequent segment to the multicast transmitter or to transmit it as a HEAD request to the content server.
