Abstract

A method and node for use in a non-linear network delivering streaming media. The node has a receiver arranged to receive data fragments from the network, each data fragment tagged with a timestamp providing a time interval relative to an epoch time reference point. A buffer is also provided for storing the received data fragments. The node also has a processor configured to calculate, on the basis of a timestamp of a data fragment stored in the buffer and a further criterion, a schedule for requesting faither fragments. A transmitter is provided for sending fragment requests at times determined by the processor as a result of the calculation. In this way, fragments are not requested unnecessarily, which reduces the amount of network traffic and reduces the processing requirements of both the node and nodes that receive the requests.
