Abstract

예를 들면 복수의 무선장치 1-1~1-5로서의 장치 ①~⑤중 장치①에 발생한 연속하는 패킷 #1~#4를 장치②~④를 중계하여 장치⑤로 송신하는 도 (A)의 시스템으로, 혼신으로 인한 패킷 상실을 막는다.For example, in FIG. (A) in which consecutive packets # 1 to # 4 generated in the device ① among the devices 1 to 5 as the plurality of radio devices 1 to 1 to 5 are relayed to the device ⑤ and transmitted to the device ⑤. The system prevents packet loss due to interference.

도(B)는 각 장치①~⑤의 교신시퀀스를 도시한 시간은 위에서 아래로 흐른다. 상기 종선중 굵은 종선부의 교신은 단발패킷 통신용 채널 #1을, 갖는 종선부의 교신은 연속패킷 통신용 채널 #2을 각각 이용하여 이루어진다. 즉, 각 장치①~④는 선두 패킷 #1을 송신하여 그 응답을 수신하면 (장치 ⑤는 패킷 #1 수신후, 그 응답을 송신하면, 채널을 #2로 전환하여 패킷 #2~#4를 송신(장치 ⑤는 수신)한다. 따라서 상기 패킷 #2~#4의 송수신 중에 도면 이외의 장치로 부터 채널 #1에 의한 단발 패킷의 송신이 이루어지더라도 연속패킷의 상실은 발생하지 않는다.Fig. (B) shows the communication sequence of each device ① to ⑤. The time flows from top to bottom. Among the vertical lines, the communication of the thick vertical line part is performed using the single-shot packet communication channel # 1, and the communication of the vertical line part has the channel # 2 for continuous packet communication. That is, when each device ① to ④ transmits the first packet # 1 and receives the response (the device ⑤ receives the packet # 1 and sends the response, the device switches the channel to # 2 and sends the packet # 2 to # 4). Therefore, even if a single packet is transmitted by channel # 1 from a device other than the figure during transmission and reception of the packets # 2 to # 4, the loss of the continuous packet does not occur.
