Abstract: PROBLEM TO BE SOLVED: To obtain a data terminal and a data transmission controller in a TCP/IP network that transfers a data packet by deciding that a receiving confirmation packet and a data packet are sent from an upper-stream direction receiving confirmation queue and an upper-stream direction data queue. SOLUTION: A queue 97 of a subscriber network terminal 100 temporarily stores a received data packet and distributes it to a subscriber's LAN through a specified route. A client terminal (PC) sends a receiving confirmation (ACK) packet, and a service provider network terminal 85 receives it through a backward (upstream) direction link 95. The client PC sends a data packet to the terminal 100 by multiplexing data to a LAN 55. A composite queue 150 of the terminal 100 forms each queue in every connection and transfers both a data packet and an ACK packet to the terminal 85 via the link 95.

Abstract: A data transmission control arrangement for an asymmetric communication system having a fast downstream link enabling communication of information packets from a service provider to one or more subscriber terminal connected through a common network terminal, and a slow upstream link including transmitting packets from a subscriber terminal through the network terminal to the service provider, the data transmission control arrangement including a classifier device for classifying information packets received by the network terminal for transmission over the upstream link, the information including data packets and acknowledgement packets; a control device for establishing one or more upstream link connection queues in the network terminal in accordance with the classification of the information packet to be transmitted, the upstream connection queues including one or more data queues for transmitting data information and ACK queues for transmitting ACK packets in response to data packets communicated over the downstream link, the control device enabling a later received ACK packet to replace one previously received ACK packets stored in a particular upstream link connection queue; and, a scheduler for servicing each of the upstream connection queues and transmitting packets from the upstream link connection queues to the service provider in accordance with transmission parameters of both upstream and downstream links.
