Tcp offload engine apparatus and method for system call processing for static file transmission

A transmission control protocol (TCP) offload engine (TOE) apparatus for static file transmission, the TOE apparatus comprising:

• a socket resource control and TCP command pool for storing a socket resource control command and a TCP connection and disconnection command;
• a message transmission and reception command pool for storing a message transmission and reception command based on the network protocol;
• a reception packet information pool for storing information of a packet whose transmission has been completed;
• a command processing completion information pool for storing results of processing the socket resource control command, the TCP connection and disconnection command and the message transmission and reception command;
• and
• a TOE-embedded processor for processing the socket resource control command, the TCP connection and disconnection command and the transmission and reception command, and processing packet transmission/reception.

A method for system call processing for static file transmission in a transmission control protocol (TCP) offload engine (TOE)-based system, the method comprising:

• receiving a division transmission command for division-transmission of a static file in units of a page of a certain size, and buffering the division transmission command to a command pool;
• determining whether the received division transmission command is the last division transmission command associated with the static file transmission;
• generating information indicating completion of command processing in response to the division transmission command regardless of actual data transmission, and transmitting the generated information to an upper layer module, if the received division transmission command is not the last division transmission command and a next division transmission command is to be buffered into the command pool;
• and
• receiving the next division transmission command.
