Abstract
Certain aspects of a method and system for transparent transmission control protocol (TCP) offload are disclosed. Aspects of a method may include collecting TCP segments in a network interface card (NIC) processor without transferring state information to a host system. The collected TCP segments may be buffered in a coalescer. The coalescer may verify that the network flow associated with the collected TCP segments has an entry in a flow lookup table (FLT). When the FLT is full, the coalescer may close a current entry and assign the network flow to the available entry. The coalescer may also update information in the FLT. When an event occurs that terminates the collection of TCP segments, the coalescer may generate a single aggregated TCP segment based on the collected TCP segments. The aggregated TCP segment and state information may be communicated to the host system for processing.
