Abstract:
A data transmission apparatus for connecting a plurality of communication nodes to transmit data via circuits established between said communication nodes, said plurality of communication nodes transmitting control data for use in controlling the data transmission and communication data other than said control data to each other, comprising:control data queuing means for queuing said control data from a first communication node transmitting data to a second communication node; control data queuing means for queuing said control data from a first communication node; communication data queuing means for queuing said communication data from the first communication node; and data transmission means responsive to a state of congestion on a data circuit between the first and second communication nodes for transmitting all of said queued control data and at least a portion of said communication data in the data queuing means from said first communication node to said second communication node in accordance with a transmission capacity between the first and second communication nodes.
