Abstract
A LAN control system including an information processing device and a plurality of LAN control sections. Each of the control sections stores a self-address, an other party address, and an other party address mask value. The source address in a received data frame is masked with the other party address mask value for comparison. This allows the control section corresponding to the source address to perform the processing of the received data frame.
