Internet layer

In the layer model of the TCP/ IP protocols, there is the Internet Layer, which lies between the Network Interface Layer( NIL) and the Transport Layer. The Internet Layer corresponds to the network layer in the OSI reference model.

The Internet Layer handles addressing, packetization of data packets and routing. In the TCP/IP protocol stack, the Internet Protocol (IP) resides on the Internet Layer, as well as the Address Resolution Protocol( ARP), Internet Control Message Protocol( ICMP), Open Shortest Path First( OSPF) and several others. As a routable protocol, the IP protocol is responsible for addressing, routing, fragmentation and reassembling of data packets.
