<p>A communication device is described that comprises a first data unit buffer for holding data units of a first communication protocol and a second data unit buffer for holding data units of a second communication protocol. The first communication protocol is a communication protocol suitable for transmitting data units from a sending peer of said first communication protocol to a receiving peer of said first communication protocol over one or more relay peers of said first communication protocol. The first communication protocol provides for at least a first type (RACK) of receipt information that is indicative of a correct receipt at a relay peer and a second type (ACK) of receipt information that is indicative of a correct receipt at said receiving peer. The second can be a conventional ARQ protocol or a protocol using the two types of receipt information. A control system is arranged to control a generation of said data units of said second communication protocol such that a data symbol stream carried in said data units of said first communication protocol is also carried in said data units of said second communication protocol, and the control system is arranged to implement the control procedure for controlling a transmission of said data units of said first communication protocol in such a way that if all the data symbols of said data symbol stream contained in a given data unit of said first communication protocol are successfully transferred into said second data unit buffer, then said control procedure acts as if said first type (RACK) of receipt information had been received for said given data unit.</p> |
