ABSTRACT:
Systems and methods that provide fault tolerant transmission control protocol (TCP) offloading are provided. In one example, a method that provides fault tolerant TCP offloading is provided. The method may include one or more of the following steps: receiving TCP segment via a TCP offload engine (TOE); calculating a TCP sequence number; writing a receive sequence record based upon at least the calculated TCP sequence number to a TCP sequence update queue in a host; and updating a first host variable with a value from the written receive sequence record.
