Abstract
A method of managing content delivery to a client device by a proxy, where the content is made up of a sequence of segments. The proxy starts off by receiving content requests from the client device over unicast, and fulfilling those requests by forwarding them to a content server, and receiving that content before forwarding onto the client device. At some stage, the proxy determines that a multicast channel should be joined to more efficiently receive the required content. However, the multicast channel is likely to be ahead of the available unicast data. Therefore, a multicast join command is delayed until the proxy has taken steps to obtain subsequent content by unicast faster than that content is being requested by the client device, so that the obtained content has caught up with the content available on the multicast channel. The proxy stores this content and uses it to respond to requests from the client device. Only then does the proxy take action to join the multicast channel.
