In some embodiments, a telecommunication network 100 comprises: a telecommunication network manager 7 for managing the telecommunication network 100 comprising a plurality of data paths 14 for media streams between telecommunication end point devices 2′,3′. The telecommunication network manager 7 comprises an input 104 to input information regarding at least: a data path along which a media stream travels for telecommunication on the telecommunication network, and the media stream; and an output 106 to output to each of a plurality of end point devices 2′,3′ using the data path an indication of bit rate to use on the data path and at least one of forward error correction rate to use on the data path and an indication of predicted packet loss rate along the data path. The telecommunication network manager 7 also comprises a processor 102 configured to process the information from the input 104 and to output from the output 106 to each of the plurality of end point devices 2′,3′ using the data path 14 an indication of bit rate and at least one of an indication of forward error correction rate to use on the data path 14 based on the information and an indication of predicted packet loss rate along the data path 14 based on the information. The telecommunication end point devices 2′,3′ each comprise an input 110 to input at least one of the indication of bit rate and forward error correction rate to use for a media stream along the data path 14 on the telecommunication network 100 and an indication of predicted packet loss rate along the data path 14 from the telecommunication network manager 7; and an output 112 to output a media stream along the data path 14 at the indicated bit rate and forward error correction rate or based on the indication of predicted packet loss rate along the data path 14. |
