TCP/IP Transmission
In the IP networking model, if the data is destined for the local host’s MAC address, the Network Interface layer information is removed.
Then, the protocol stack passes the packet to the Internetwork layer.
In the Internetwork layer, the destination IP address contained in the packet is compared to the local host’s IP address.
If the IP address listed in the data packet matches the local host IP address, or is a broadcast, the protocol stack strips off the Internetwork layer information and moves the packet up the protocol stack.
