As We've learnt in short article on OSI and TCPIP Principles, TCPIP packet is made up of informations necessary to establish the network relationship. It is made up of resource IP handle, location IP address, port quantities, sequence numbers, protocol type and so on. Every one of these fields are crucial for network layer of OSI stack to function appropriately. As described TCPIP protocol mainly helps in trusted packet transmission around ethernet.
