Abstract
A packet transmission apparatus includes a processor such as a CPU, a first processing chip, and a second processing chip. The second processing chip is separately connected to the processor and the first processing chip. For example, it may be considered that the second processing chip is disposed between the processor and the first processing chip. The first processing chip is a non-programmable chip such as an ASIC chip, and the second processing chip is a programmable chip such as an FPGA chip. The second processing chip supports a second functional, and the second functional is updatable. Both the processor and the first processing chip are configured to exchange a packet with the second processing chip. The second processing chip is configured to process a received packet based on the second functional, and send the processed packet to the processor or the first processing chip.
