The present invention relates to nodes and methods for use in connection with a peer-to-peer network for sharing of data content. A priority mechanism is introduced by means of which a serving peer may select which requesting peers to serve based on their need for data content in terms of the degree of urgency. A requesting peer may include an urgency indicator in a request for data content, which for instance may be the amount of buffered data available for playback in a video buffer. The serving peer may then extract the urgency indicator from the request and apply a priority mechanism which uses the urgency indicator to select which peers to upload data content to.

Methods and arrangements for prioritization in a peer-to-peer network

A method of controlling access to content comprises receiving, at a domain gateway () of a domain (), a request from a device () in the domain for access to the content. It is determined at the domain gateway whether the number of devices in the domain currently accessing the content is equal to a specified maximum number of devices that may simultaneously access the content. The maximum number of devices that may simultaneously access the content is independent of the number of devices in the domain. If the determination is that the number of devices in the domain currently accessing the content is less than the specified maximum number the request is allowed, otherwise it is refused.
