Abstract: An apparatus for generating and managing TCP(Transmission Control Protocol) transmission information based on a TOE(TCP Offload Engine) and a method thereof are provided to reduce load of a system due to the increase and re-transmission of transmission information, by reducing the number of memory access and managing information of transmission data by using hardware. In an apparatus for generating and managing TCP(Transmission Control Protocol) transmission information based on a TOE(TCP Offload Engine), a dedicated TCP transmission processing unit(110) generates transmission information on the basis of address and size information of transmission data by receiving data transmission request of a network program, and deletes the corresponding transmission information when the transmission is completed. A dedicated TCP reception processing unit(120) generates and manages reception information on the basis of address and size information of an area used in receiving data by receiving a reception command of data. A transmission information area management unit(130) allocates a memory area to store transmission information according to the command of the dedicated TCP transmission processing unit, and generates an identification(ID) of a corresponding area, and manages deletion processing. A storing unit(140) stores and deletes transmission information according to the control of the dedicated TCP transmission processing unit.

Abstract: Provided is an apparatus for detection timeout of each channel, which is a socket connection, in a Transmission Control Protocol (TCP) Offload Engine (TOE) using TCP accelerating hardware, and a method thereof. The timer managing apparatus of the TOE using the TCP accelerating hardware, including: a command register for receiving a command for a retransmission timer or a delayed ACK timer from an embedded processor of the TOE; a finite state machine (FSM) for storing information of a timer in operation by analyzing the command for the retransmission timer or the delayed ACK timer stored in the command register and controlling an entire operation of the timer managing apparatus; and a timeout checker for checking timeout of a timer in operation by using the stored timer information and notifying the timeout to the FSM.
