Abstract
A TCP offload system is disclosed including apparatuses and methods for batching session (sometimes called application) layer headers to reduce interrupts as well as CPU copies. One embodiment includes receiving a plurality of TCP packets, comprising processing the packets by TCP, including removing TCP headers from TCP data, associating the TCP data with a TCP connection for an application, and updating a TCP control block (TCB) that defines the TCP connection; locating a plurality of upper layer headers in the TCP data, the headers each corresponding to application data contained in the packets, wherein the plurality of upper layer headers correspond to a protocol that is higher than TCP; processing the plurality of upper layer headers by the application to obtain memory locations for the application data; and placing the application data in the locations, after the processing of the plurality of upper layer headers by the application.
