As we have learnt in report on OSI and TCPIP Fundamentals, TCPIP packet is made up of informations necessary to ascertain the network relationship. It consists of source IP tackle, desired destination IP address, port numbers, sequence numbers, protocol sort etcetera. These fields are crucial for network layer of OSI stack to function appropriately. As outlined TCPIP protocol essentially allows in reputable packet transmission more than ethernet.
