摘要
A communication managing apparatus (CMA) that manages transmission of data employing a token passing system in a network in which a plurality of communication apparatuses (CAs) are connected via a transmission line. The CMA includes a network-presence checking unit performing network presence checking processing for transmitting, by broadcast, a network presence check frame for recognizing the CAs, receiving, from the CAs, frames including thereof, and generating connection information indicating a connection state via the ports. The CMA further comprises a unit determining token circulation order using the connection information, a setup processing unit performing, based on the token circulation order, setup processing for notifying the communication apparatuses of a communication apparatus to which a transmission right is giving next, and a data-fame-communication processing unit performing transmission and reception of a data frame using a token frame.
