20100014419 | APPARATUS AND METHOD FOR IMPROVING TRANSPORT CONTROL PROTOCOL PERFORMANCE USING PATH RECOVERY NOTIFICATION OVER WIRELESS NETWORK - Provided are an apparatus and method for improving transmission control protocol (TCP) performance using path recovery notification over a wireless network. The apparatus includes: a path recovery manager which detects a mobile host recovered from a temporary disconnection state and then outputs a detection signal to notify the detection result; a path recovery notification manager which receives the detection signal and generates an ACK (acknowledgement) packet to inform a transmitting end that the mobile host is recovered; and a first packet transceiver which transmits/receives the generated ACK packet and a data packet. Accordingly, a temporary disconnection state of a wireless network is explicitly informed to a transmitting end so as to transmit only lost packets without performing unnecessary congestion control, thereby improving TCP performance. | 01-21-2010 |
