摘要： A communication system capable of improving a TCP transmission efficiency includes a transmitter for transmitting data packets; a receiver connected to the transmitter, and for receiving the data packets and transmitting to the transmitter response signals with respect to the received data packets; and a multiplexer for multiplexing and transmitting to the transmitter the response signals transmitted from the receiver, and transmitting the transmitted data packets from the transmitter to a corresponding receiver, the multiplexer provided with a queue status monitor for monitoring queue statuses of the transmitted data packets and/or response signals, and a congestion control adjuster instructing the receiver to hold or compress the response signals based on the monitored queue status. Accordingly, the communication system can carry out efficient TCP congestion control by reducing a load of the TCP congestion control of the transmitters and receivers.

摘要： A wireless communication system has a queue information search unit for searching a queue-status information provided in a packet unit, a communication priority decision unit for deciding communication priority of external devices based on the queue-status information, giving a higher priority to the external device having a greater number of packets in queues, a communication initiation unit for initiating a communication with the external devices according to the communication priority, a counter for counting the number of times that the communication is initiated for each of the external devices, and a comparator for comparing a counter value of a first external device that corresponds to a transmitted data with a counter value of a second external device that has a maximum counter value. Accordingly, when the wireless communication device transmits and receives data with respect to the plural wireless communication devices, both high throughput and high fairness can be guaranteed.
