Abstract

In a network system which sequentially passes a right to transmit in the form of a token and includes a plurality of data processors, at least one of the plurality of data processors is set so as to be able, during each possession of the token, to send messages in greater number than those transmitted by each of the remaining data processors by at least one. The data processor that is allowed to send many messages consecutively sends messages by inserting, into a token address field included in a message format, its own address during transmission. In the case of a server/client network, a server is set so as to consecutively send a number of messages at a time, while in possession of the token.
