Abstract
Disclosed is a broadband wireless network, and more particularly, to a method for transmitting and receiving a TCP ACK packet, and a device supporting the same, wherein the method for transmitting and receiving a TCP ACK packet receiving TCP ACK packets and data packets from an upper layer; creating a MAC PDU by unifying the TCP ACK packet and data packet buffered in the same queue among the received TCP ACK packets and data packets; and transmitting the MAC PDU to a physical layer.
Claims19
A method for transmitting a TCP ACK packet comprising:
- receiving TCP ACK packets and data packets from an upper layer;
- creating a MAC PDU by unifying the TCP ACK packet and data packet buffered in the same queue among the received TCP ACK packets and data packets;
- and
- transmitting the MAC PDU to a physical layer,
- wherein the unifying process is carried out by unifying TCP ACK information contained in a TCP header of the TCP ACK packet buffered in the same queue with header information contained in a TCP header of the data packet buffered in the same queue.
A method for receiving a TCP ACK packet comprising:
- receiving a MAC PDU including a data packet unified with the TCP ACK packet;
- checking whether or not TCP/IP header and ACK field are included in the received MAC PDU;
- extracting the TCP/IP header from the MAC PDU when the TCP/IP header and ACK field are included in the received MAC PDU;
- restoring the TCP ACK packet including the TCP ACK information through the use of extracted TCP/IP header;
- and
- resetting TCP header checksum of the TCP/IP header from which the TCP ACK information is extracted.
A device for supporting a TCP ACK packet transmission comprising:
- a detecting unit for detecting a first packet including TCP ACK information, and a second packet including data payload among plural packets queued in the same queue;
- and
- a packet unifying unit for forming a TCP/IP header of SDU by extracting the TCP ACK information from the first packet, and forming a payload of the SDU by extracting the data payload from the second packet,
- wherein a TCP checksum (CRC) included in the TCP header of the SDU is reset by reflecting the TCP ACK information thereon.
