Zusammenfassung:PROBLEM TO BE SOLVED: To provide a communication system capable of suppressing a load increase caused by the issue of an ARP command, with the suppression of the increase of cost and a labor.SOLUTION: The communication system includes: a server device; a plurality of terminal devices to which communication data is transmitted from the server device in broadcast; an electronic device; and a layer-3 network device which connects the above devices to an identical LAN. The layer-3 network device includes an ARP table storage unit. Each terminal control unit of the plurality of terminal devices answers to the server device and the electronic device, in response to communication which at least includes a content destined to the self-device from the server device. The electronic device includes a processing device including: a list storage unit which stores an IP address list of the terminal devices; and a processing control unit which performs predetermined communication with the plurality of terminal devices at mutually different timings before the lapse of an invalidated period of the ARP table.SELECTED DRAWING: Figure 2 【課題】コストや手間の増加を抑えながら、ARPコマンドの発行による負荷の上昇を抑えることの出来る通信システムを提供する。【解決手段】サーバ装置と、サーバ装置からブロードキャストで通信データの送信が行われる複数の端末装置と、電子機器と、これらを同一LAN内に接続するレイヤ3ネットワーク装置と、を備え、レイヤ3ネットワーク装置は、ARPテーブル記憶部を備え、複数の端末装置の端末制御部は、サーバ装置からの少なくとも自装置宛の内容を含む通信に対してサーバ装置及び電子機器に対して返信を行い、電子機器には、端末装置のIPアドレスのリストを記憶するリスト記憶部と、ARPテーブルの失効時間の経過前に複数の端末装置に対して各々異なるタイミングで所定の通信を行う処理制御部とを備える処理装置が含まれる。【選択図】図2
