Abstract

PURPOSE:To optimize a transmission scheduling, by taking into consideration data length of transmission data, transmission speed and transmission delay time of each communication line and selecting the line in use so that the utilization factor and transmission time of each communication line can be constant. CONSTITUTION:A communication system 1 is provided with communication system HDLC control sections 61, 62... connecting communication systems using a pluraity of lines connected to a plurality of communication lines 51, 52... via MODEMs 31, 32... and a scheduling control section 10, and a transmission data Ds is inputted and stored to a first-in/first-out FIFO CUE14 sequentially for storage, and if a transmission waiting CUE12 of the HDLC section 61... corresponding to each line 51... is vacant, the line number is stored in a vacant display latch 18, a gate 15 is opened by it, a transmission data is picked up from a open CUE14 and inputted to a data length detection/share section 16. The data length is measured, the line in use is selected by using a delay time of each line, the data is inputted to the transmission waiting CUE12 in the HDLC control section of the said line via a switching device 17 and transmission is made.
