There is described a method of delivering data from a server to a client device in a network. Data packets with a first source address are sent in a first session from the server to the client device. A Session Switch Information (SSI) message, including a second source address, is sent from the server to the client device. A second session is configured between the server and the client device, and data packets with a second source address are sent in the second session from the server to the client device. The same transport protocol may be used for both sessions, and the method can be 10 used to switch between unicast and multicast delivery. |
