1. A communication device, comprisinga first data unit buffer for holding data units of a first communication protocol, where said 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, providing for feedback messages sent in a direction of said sending peer of said first communication protocol. where said feedback messages carry information on a receipt of said data units of said first communication protocol, said first communication protocol providing for at least a first type and a second type of receipt information, said first type (RACK) of receipt information being indicative of a correct receipt at a relay peer and said second type (ACK) of receipt information being indicative of a correct receipt at said receiving peer, and where said first communication protocol provides that said sending peer of said first communication protocol uses a sending peer control procedure for controlling a transmission based on said feedback messages of said first communication protocol, and each relay peer of said first communication protocol uses a relay peer control procedure for controlling a transmission based on said feedback messages of said first communication protocol,a second data unit buffer for holding data units of a second communication protocol, where said second communication protocol is a communication protocol suitable for transmitting data units from a sending peer of said second communication protocol to a receiving peer of said second communication protocol, which provides for feedback messages sent in a direction of said sending peer of said second communication protocol, where said feedback messages of said second communication protocol carry information on a receipt of said data units of said second communication protocol, said second communication protocol providing for a specific type of receipt information that is indicative of a correct receipt at said receiving peer of said second communication protocol, and where said second communication protocol provides that said sending peer of said second communication protocol uses a control procedure for controlling a transmission based on said feedback messages of said second communication protocol and the receipt information contained therein, anda control system 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, said control system being 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 for controlling a transmission of said data units of said first communication protocol acts as if said first type (RACK) of receipt information had been received for said given data unit.
