Summary: | To provide a communication device, a communication system and a communication method which can suppress a delay caused by a collision between packets.SOLUTION: The communication device includes: a plurality of queues which store packets; an input unit which inputs a packet to a queue among the plurality of queues according to the priority of the packet; an addition unit which, when the packet is input to the queue according to the priority, acquires a first time to add to the packet; a readout unit which preferentially reads out each packet having higher priority from each of the plurality of queues; a calculation unit which, when the packet is read out from each of the plurality of queues, acquires a second time to calculate a packet delay time from a time difference between the first time and the second time; and a priority control unit which raises the priority of the packet according to the delay time.SELECTED DRAWING: Figure 14
【課題】 パケット同士の衝突による遅延を抑制することができる通信装置、通信システム、及び通信方法を提供する。【解決手段】 通信装置は、パケットを格納する複数のキューと、前記複数のキューのうち、パケットの優先度に応じたキューにパケットを入力する入力部と、パケットが前記優先度に応じたキューに入力されるとき、第1の時刻を取得してパケットに付与する付与部と、前記複数のキューの各々から、前記優先度が高いパケットほど優先的に読み出す読出部と、パケットが前記複数のキューから読み出されたとき、第2の時刻を取得して、前記第1の時刻と前記第2の時刻の差分からパケットの遅延時間を算出する算出部と、前記遅延時間に応じてパケットの前記優先度を上げる優先度制御部とを有する。【選択図】図14 |
