<p><P>PROBLEM TO BE SOLVED: To achieve complicated QoS control and transmit a packet at correct time. <P>SOLUTION: A packet type identification unit 101 identifies the type of a packet and enqueues the packet to a queue corresponding to the identified packet type among queues 102-1 to 102-n with QoS values set according to the corresponding packet type. For each packet in each queue, a scheduler unit 103 calculates estimated transmission time based on the QoS value of the queue, and dequeues the packet and outputs the packet to a hardware control unit 200 together with time information that indicates the estimated transmission time. A buffer storage processing unit 210 sorts the packets output from the scheduler unit 103 in the order of estimated transmission time, and stores the sorted packets in a buffer unit 220. A transmission processing unit 230 transmits each packet stored in the buffer unit 220 at the estimated transmission time of each packet. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
