A packet switching system mainly consists of a packet transmission controller, connected to a line group, for performing transmission control of a data packet, and a packet switching unit for receiving the data packet from the packet transmission controller to perform switching processing. The packet switching unit includes a packet separator for separating the data packet into a header part and a data part, a packet header processor for updating the separated header part, a packet data buffer for storing the separated data part, and a packet combiner for combining the output from the packet data buffer and the output from the packet header processor and supplying a combined packet to the packet transmission controller.
