Aspects of the invention may comprise receiving an incoming TCP packet at a TEEC and processing at least a portion of the incoming packet once by the TEEC without having to do any reassembly and/or retransmission by the TEEC. At least a portion of the incoming TCP packet may be buffered in at least one internal elastic buffer of the TEEC. The internal elastic buffer may comprise a receive internal elastic buffer and/or a transmit internal elastic buffer. Accordingly, at least a portion of the incoming TCP packet may be buffered in the receive internal elastic buffer. At least a portion of the processed incoming packet may be placed in a portion of a host memory for processing by a host processor or CPU. Furthermore, at least a portion of the processed incoming TCP packet may be DMA transferred to a portion of the host memory.

1. A system for processing TCP packets during communication, the system comprising: a delay compensation buffer of a network interface card operable to temporarily store TCP packets;a TCP offload packet processor of the network interface card operable to process headers of the TCP packets from the delay compensation buffer, the processing including determining placement information and excluding reassembly and retransmission of the TCP packets;the TCP offload packet processor further operable to transfer at least a portion of the TCP packets to memory of a host upon determining placement information for the TCP packets by the TCP offload packet processor; anda processor of the host operable to reassemble or reorder out-of-sequence TCP packets in the memory of the host. 2. The system according to claim 1, wherein the delay compensation buffer compensates for delay that is caused by factors external to the system. 3. The system according to claim 1, wherein the delay compensation buffer compensates for delay that is caused by factors internal to the system. 4. The system according to claim 1, wherein the delay compensation buffer comprises a receive buffer and a transmit buffer. 5. The system according to claim 1, wherein the delay compensation buffer comprises a receive buffer operable to compensate for an external network delay. 6. The system according to claim 1, wherein the delay compensation buffer comprises a transmit buffer operable to compensate for an internal system delay. 7. The system according to claim 1, wherein said at least a portion of the TCP packets comprise a payload portion. 8. The system according to claim 1, wherein the TCP offload processor is operable to place at least data from an incoming TCP packet into a highest hierarchy of buffer available in the memory of the host by performing a single copy operation. 9. A method for processing TCP packets during communication, the method comprising: receiving, by a TCP offload processor of a network interface card, TCP packets;temporarily storing, by the TCP offload processor, TCP packets in a delay compensation buffer of the network interface card;processing, by the TCP offload processor, headers of the TCP packets from the delay compensation buffer including determining placement information, the processing excluding reassembly and retransmission of the TCP packets;electronically transferring at least a portion of the TCP packets to memory of a host upon determining placement information for the TCP packets by the TCP offload packet processor; andreassembling or reordering out-of-sequence TCP packets in the memory of the host. 10. The method according to claim 9, wherein the delay compensation buffer compensates for delay that is caused by factors external to the network interface card. 11. The method according to claim 9, wherein the delay compensation buffer compensates for delay that is caused by factors internal to the network interface card. 12. The method according to claim 9, wherein the delay compensation buffer comprises a receive buffer operable to compensate for an external network delay. 13. The method according to claim 9, wherein the delay compensation buffer comprises a transmit buffer operable to compensate for an internal system delay. 14. The method according to claim 9, wherein said at least a portion of the TCP packets comprise a payload portion. 15. The method according to claim 9, further comprising placing at least data from incoming TCP packet into a highest hierarchy of buffer available in the memory of the host by performing a single copy operation. 16. A non-transitory machine-readable storage medium, having stored thereon, instructions for providing TCP offload, the instructions being executable by a processor of a network interface card for causing the processor to perform: receiving TCP packets;temporarily storing the TCP packets in a delay compensation buffer of the network interface card;processing headers of the TCP packets from the delay compensation buffer including determining placement information and excluding reassembly and retransmission of the TCP packets;electronically transferring at least a portion of the TCP packets to memory of a host upon determining placement information for the TCP packets by the processor; andplacing at least a portion of the processed TCP packets into host buffers in the memory of the host for reassembly. 17. The non-transitory machine-readable storage medium according to claim 16, the instructions further causing the processor to perform placing at least data from incoming TCP packet into a highest hierarchy of buffer available in the memory of the host by performing a single copy operation.
