ABSTRACT:
A dispatch mechanism is provided for dispatching data units, (e.g. datagrams or packets) divided into one or more fragments, via a telecommunications network. The dispatch mechanism includes a queue for queuing fragments for transmission. It further includes a queue controller operable when a fill level of the queue exceeds a threshold value to discard fragments of data units for which a fragment has not already been queued and to add to the queue fragments of data units for which a fragment has already been queued. The dispatch mechanism maintains a record of data units which are to be transmitted (that is when one fragment of the data unit has already been passed for despatch) and a record of data units which are to be dropped (that is data units for which a fragment has already been dropped). The dispatch mechanism enables more effective use of network capacity by reducing the possibility of incomplete data units being transmitted over the network. In other words, where one data unit fragment is dropped, a mechanism ensures that all remaining fragments of that data unit are dropped. Also, where one data unit fragment has been sent, the mechanism ensures that all other fragments for that data unit are sent, irrespective of the fill level of the output queue when a data fragment for transmission is processed.
