Abstract: A content distribution system is provided comprising a content client and a content server connected through a network. The content server is configured to send the content client a session description comprising at least one media description to enable it to receive over the network a content item. The system comprises a network monitor for monitoring network traffic going through the network, and a recommender for marking in dependency upon the network monitor, one or more of the media descriptions in the session description to obtain a marked session description. The marked media description recommends the content client to prefer certain content above others in view of the current network condition. For example, if available bandwidth is low, content is recommended which requires low bandwidth. Network congestion is thereby avoided for all users of the system.
