Abstract: In order to achieve a packet processing device which make it possible to process a packet at high speed, a bus that transfers a communication packet, and a plurality of processors and executes at least one task including either of a first task and a second task are included, wherein the first task performs processing when a first task identifier given to the first task and a second task identifier added to the communication packet received from the bus coincide with each other, the second task performs the processing for the communication packet that is not added with the second task identifier, and the processing executes first processing, based on the packet identifier, and thereafter, adds, to the communication packet, the second task identifier indicating the different first task that executes second processing subsequent to the first processing, and transmits the communication packet to the bus.
