1. A communication device comprising:

  • a discriminator means arranged for receiving and discriminating data packets of a second data structure according to predetermined rules on the basis of contents of said data packets of said second data structure;

    an embedding device for generating data packets of a first data structure determined by a first predetermined protocol, said embedding device being arranged to receive said data packets of said second data structure and generate said data packets of said first data structure by embedding each of said data packets of said second data structure in at least one of said data packets of said first data structure; and

    wherein said embedding device is adapted to adjust an operation mode for at least one of said data packets of said first data structure on the basis of a discrimination result relative to at least one of said data packets of said second data structure, said embedding device for setting a transmission reliability mode in each said data packet of said first data structure prior to sending each said data packet of said first data structure, wherein said first predetermined protocol supporting at least two transmission reliability modes according to which said data packets of said first protocol are sent, where said transmission reliability modes are distinguishable at least with respect to rules regarding the retransmission of said data packets of said first data structure, and where each said generated data packet of said first data structure contains information on the associated transmission reliability mode according to which said data packet of said first data structure is to be sent, such that a receiver of each said data packet of said first data structure may determine according to which of said transmission reliability modes which of said data packets of said first protocol were sent;

    said discriminator means being arranged to discriminate a given data packet of said second data structure according to said predetermined rules, such that the information on the transmission reliability mode in the at least one of said data packets of said first data structure containing said given data packet of said second data structure is set in accordance with the discrimination result;

    an output buffer, into which the data packets of said first data structure are passed; and

    said output buffer being arranged to place each data packet of said first data structure in a queue associated with the transmission reliability mode set in said each packet; and

    wherein a first transmission reliability mode comprises rules for the retransmission of data packets under predetermined conditions and a second mode provides for no retransmission of data packets, and said output buffer is arranged to send out data packets of said first mode that are to be retransmitted with a higher priority than other data packets.
