Abstract: In an exemplary communication apparatus, an assignment module determines whether processing for a second packet assigned the flow ID associated with a received first packet is being executed. The assignment module determines a parallel processing module to execute processing for the first packet and a parameter to be included in a notice of assignment. The determined parallel processing module acquires a result of execution of the processing for the second packet from the computation table or the result of execution of the processing held in the parallel processing module according to the received notice of assignment. The determined parallel processing module executes the processing for the first packet using the result of execution of the processing for the second packet and the information included in the notice of assignment, and updates a computation table with a result of execution of the processing for the first packet.
