PROBLEM TO BE SOLVED: To achieve acceleration and price reduction by partially charging TCP (transmission control protocol) processing between hardware processing due to an offload unit and software processing due to a CPU. SOLUTION: A method and apparatus for processing data received and transmitted on a TCP connection is described. An offload unit processes received data for which a special case does not exist, to generate payload data which are uploaded directly to an application memory. The offload unit partially processes the received data for which a special case does exist and uploads the partially processed received data to a buffer stored in a system memory. The partially processed received data are then, further, processed by a TCP stack to produce payload data which are copied to the application memory. COPYRIGHT: (C)2010,JPO&INPIT |
