<p>PROBLEM TO BE SOLVED: To transfer a packet whose priority is high, such as voice data with no increase in transfer delay, related to a method and device of transferring packets for transferring variable-length packets. SOLUTION: A transmission side comprises an interrupt transmission queue 3, wherein an interrupt synchronization pattern is added before and after a packet of high priority, such as voice data, to synchronize byte with other packet for interrupt inserting which is sent out, and a normal transmission queue 2, which receives packets other than those of high priority and sequentially transfers them to the interrupt transmission queue 3. A reception side comprises an interrupt reception queue, which detects the interrupt synchronization pattern to separate/extract packets of high priority, and a normal reception queue which receives packets other than those of high priority which are separated/extracted by the interrupt reception queue. The voice data, etc., are taken as a packet of high priority for RTP protocol, and interruptively inserted in packets having low priority for sending out, without waiting.</p> |
