Abstract A communication device includes: multiple queues, each of which stores a packet; an input section that inputs a concerned packet to a queue that is among the multiple queues and corresponds to a priority of the concerned packet; an adder that acquires first time when the concerned packet is input to the queue corresponding to the priority, and that adds the first time to the concerned packet; a reader that reads packets from each of the multiple queues in order from a packet with the highest priority; a calculator that acquires second time when the concerned packet is read from the queue corresponding to the priority, and that calculates delay time of the concerned packet from the difference between the first time and the second time; and a priority controller that increases the priority of the concerned packet based on the delay time.
