ABSTRACT:
The present invention relates to a communicating data system comprising devices (11, 12, 13, 14) for routing said data that are interconnected by communication links, the data being transmitted in packets and a packet comprising a header. A transmitting part of a first routing device (12) comprises first storage means suitable for storing a value of at least one parameter from said header and for transmitting a coded value corresponding thereto, and first entropy coding compression means which are suitable for recoding the uncoded value, the recoded value being stored instead of the coded value after the latter is transmitted along a communication link (15). A receiving part of a second routing device (13), that is connected to the first routing device by the communication link, comprises second storage means suitable for storing the coded value coming from the communication link (15) and for transmitting the uncoded value corresponding thereto, and second entropy coding compression means which are suitable for recoding the uncoded value, the recoded value being stored instead of the coded value.
