<p>A packet scheduling apparatus for reducing a transmission delay and a transmission jitter, caused by transmitting a low-priority packet, of a premium packet and for transmitting the low-priority packet efficiently. The packet scheduling apparatus comprises a packet input unit (1), a packet queue group (2), a scheduler unit (3), a packet division unit (4), a packet output unit (5) and a packet buffer (6). The packet queue group (2) includes a premium packet queue (21) and a low-priority packet queue (22). The scheduler unit (3) includes a scheduling queue (31) and a scheduler (32). The 'low-priority packet' to influence the transmission of the 'premium packet' is divided by the packet division unit (4) into a plurality of packets having such a length that they can be within the transmission interval of the 'premium packet', and a schedule is dynamically made on the basis of the transmission interval or loading situation of the 'premium packet'.</p> |
