TRANSPORT LAYER CONTROL DEVICE, METHOD FOR TRANSMITTING PACKET, AND METHOD FOR RECEIVING PACKET
First Claim
1. A transport layer control device to transmit or receive a plurality of packets, comprising:
- a controller to establish or release a transmission control protocol (TCP) connection and to process retransmission of lost packets using TCP; and
a packet processor to number packets and to process transmission of the numbered packets using a user datagram protocol (UDP).

Abstract
A transport layer control device includes a controller to establish or release a transmission control protocol (TCP) connection and to process retransmission of a lost packet using TCP, and a packet processor to number packets and to process transmission of the numbered packets using a user datagram protocol (UDP). A method for transmitting a packet includes establishing the TCP connection with a receiving device, numbering packets and transmitting the numbered packets to the receiving device using UDP, and retransmitting a lost packet to the receiving device using TCP in response to a retransmission request for the lost packet. A method for receiving a plurality of packets includes establishing the TCP connection, receiving numbered packets using UDP, requesting retransmission of a lost packet using TCP, and receiving the lost packet through TCP.
