ABSTRACT:
A plurality of terminals are connected via LAN to a traffic control unit for allocating time slots in response to data transmission requests and for monitoring the LAN load. The traffic control unit includes a load monitoring section, a high traffic mode noticing section, a time slot noticing section and a high traffic mode releasing section and each of terminals includes a high traffic mode receiving section, a transmission control section, a time slot requesting section and an end noticing section. When the load monitoring section detects the high traffic state of the LAN, the high traffic mode noticing section notices to all the terminals that the system is set in a high traffic mode. When the high traffic mode receiving section of each terminal receives the notice, the high traffic mode is set. In the high traffic mode, the time slot requesting section in each terminal issues a time slot allocating request to the time slot noticing section only for the first data transmission after the high traffic mode has set, and the time slot noticing section allocates a time slot to the requesting terminal. When ending the data transmission the end noticing section the transmission end to the traffic control unit. When the load monitoring section detects the low traffic state, the high traffic mode releasing section notices to all the terminals that the system be set in a normal mode.
