The system uses the client and server-side development mode. On the client side, we design two processes, P1 and P2, and read the data on the network card. After reading data, P1 is responsible for writing the header data in the TCP message to the Packet file. After P2 reads the data, it is responsible for writing the header of the UDP message to Packet file as well.
