Publication number: 20110116483Abstract: A server may be bypassed in the context of retransmitting data packets, when such data packets are missing or lost due to interference or some other network error. Decreased throughput and other disadvantages associated with data packet retransmission are avoided by negating the need to transmit retransmission request packets to the server and retransmitting a missing/lost data packet from the server. Instead, retransmission request packets may be sent to a router, and the router may respond by directly retransmitting the missing/lost data packet to the client, where prior to retransmitting the missing/lost data packet, it is determined whether the data packet is a Transport Control Protocol or User Datagram Protocol packet, and proceeding with the retransmitting only if the data packets is a Transport Control Protocol packet.Type: ApplicationFiled: November 13, 2009Publication date: May 19, 2011Inventors: Yong Sang Lee, Seung Beom Kim
