Abstract
A method of managing content delivery to a client device via a proxy is described. The proxy starts off by receiving content requests from the client device over unicast, and fulfils 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 it may be possible to join a multicast channel to more efficiently receive the required content. However, before a switch is made, the proxy gathers multicast delivery timing data from the content server without joining the multicast group, and behavioural characteristics of the client device. The proxy uses this data to determine whether the client device would change the quality level of the content segments being requested.
