| description | To suppress useless communication.SOLUTION: In a communication system, a path of a frame is restricted. The communication system includes: a switch 210 present in a connection path connected to a terminal device 100; and a switch 230 present in a connection path between the terminal device 100 and a terminal device 110. The switch 210 includes: a port A included in the connection path connected to the terminal device 100; and a storage unit 211 storing a learning table 212 indicating a MAC address of the terminal device 100 and the port A. The switch 230 includes: a port A included in the connection path connected to the terminal device 100; and a storage unit 231 storing a learning table 232 indicating the MAC address and the port A of the terminal device 100 on the basis of the learning table 212. The switch 230 transmits a frame 21 from the port A with reference to the learning table 232 when receiving the frame 21 having the MAC address of the terminal device 100 as a destination address.SELECTED DRAWING: Figure 4
【課題】無駄な通信を抑制すること。【解決手段】通信システムでは、フレームの経路が制限されている。通信システムは、端末装置１００との接続経路に存在するスイッチ２１０と、端末装置１００及び端末装置１１０との接続経路に存在するスイッチ２３０とを含む。スイッチ２１０は、端末装置１００との接続経路に含まれるポートＡと、端末装置１００のＭＡＣアドレスとポートＡとを示す学習テーブル２１２を記憶する記憶部２１１と、を有する。スイッチ２３０は、端末装置１００との接続経路に含まれるポートＡと、学習テーブル２１２に基づいて、端末装置１００のＭＡＣアドレスとポートＡとを示す学習テーブル２３２を記憶する記憶部２３１と、を有する。スイッチ２３０は、端末装置１００のＭＡＣアドレスを宛先アドレスとするフレーム２１を受信した場合、学習テーブル２３２を参照して、フレーム２１をポートＡから送信する。【選択図】図４ |
