摘要： A communication system and communication method having protocols used are to priorly process real-time data without delay. Information of a protocol header of data to be sent or received is used as priority decision information to decide whether or not the data should be priorly send- or receive-processed. The information to be priorly processed of combination of the priority decision information is registered and managed as priority data information before being stored. The data send or receive process fetches the priority decision information from the send or receive data before deciding whether or not the data are registered as the priority data information. If so, the data are send- or receive-processed prior to the data that are not registered. The communication system and communication method can priorly control the data to be processed in real time without limiting communications for each of the data treated by an application communication program even if the real-time data are mixed with non-real-time data.
摘要翻译：具有所使用协议的通信系统和通信方法是无延迟地事先处理实时数据。将要发送或接收的数据的协议报头的信息用作优先级判定信息，以决定数据是否应该先发送或接收处理。要优先处理的优先权决定信息的组合的信息在存储之前作为优先数据信息被登记和管理。数据发送或接收处理在确定数据是否被注册为优先数据信息之前，从发送或接收数据中取出优先级决定信息。如果是这样，数据将在未注册的数据之前进行发送或接收处理。通信系统和通信方法可以实时地控制要处理的数据，而不会限制由应用通信程序处理的每个数据的通信，即使实时数据与非实时数据混合。

摘要： A network system includes at least one computer which includes a processor for processing data and attaching an associated contents code corresponding to the processed data and data group information indicative of a data group corresponding to the attributes of the processed data to ask a data transmission request and a transmission controller connected to the processor for controllably transmitting a frame including the transmission sub-network, the contents code and the processed data to the first sub-network according to the data group information of the processed data. A second computer connected judges whether or not the contents code of the frame received from the first sub-network conforms to one of a plurality of data reception enable/disable judgement conditions. A third computer judges whether or not the contents code of the frame received conforms to one of a plurality of data reception enable/disable judgement conditions, and storing the received frame having the contents code conforming to one of the plurality of data reception enable/disable judgement conditions. The second computer includes a filter in which the contents codes differently set for respective sub-networks are stored and which changes the contents code contained in the received frame to the contents code set for the receiving sub-network.
