Abstract:
An ATM multiplex apparatus connected to information terminals for multiplexing information to be communicated and transmitting the multiplexed information via an ATM network, comprising:an interface unit interfacing with said information terminals; a multiplex unit multiplexing information from said information terminals to transmit to said ATM network; and a main control unit controlling said interface unit and said multiplex unit, wherein said multiplex unit comprises: a congestion level detect unit detecting a congestion level of information to be transmitted to said ATM network, and a congestion signal report unit generating signals indicative of a congestion level detected by said congestion level detect unit and outputting said signals directly to said interface unit without routing through said main control unit, wherein said interface unit accepts said signals indicative of the congestion level directly from said congestion signal report unit, and executes a congestion control for said information terminals in accordance with the congestion level indicated by said signals, thereby eliminating time lags between an occurrence of congestion and start of congestion control.
