ABSTRACT:
A packet scheduling apparatus which decreases a transmission delay and a transmission jitter of a premium packet which occur by transmitting a low priority packet and which efficiently transmits the low priority packet is provided. The apparatus includes a packet input section1, a packet queue group2, a scheduler section3, a packet dividing section4, a packet output section5and a packet buffer6. The packet queue group2includes a premium packet queue21and a low priority packet queue22. In addition, the scheduler section3includes a scheduling queue31and a scheduler32. The “low priority packet” which influences the transmission of the “premium packet” is divided into a plurality of packets each having a length which falls within a transmission interval of the “premium packet” by the packet dividing section4, and scheduled dynamically based on the transmission interval or load state of the “premium packet”.
