Internetworking

In internetworking the routers has the information regarding the addresses for the nodes that is in the network.

They are then configured to switch to the varied network or they can do it by using the internetworking protocol.

Internetworking is the communication within the network by the nodes among each other for passing data.

Tunneling

Tunneling is the dedicated connection or arrangement for transferring the data into the geographical region.

It is like a tunnel we have made for the communication between the nodes in the network.

The arrangement of the network is done between the dedicated physical connectivity or using the established existing network for the transfer of data.

Packet Fragmentation

If the data is more than the packet size then there may be  a chance  that data gets lost in between the transfer.

Then one solution can be made just breaking the packet data into pieces and then we will forward it one after another.

The process of breaking and sending data is known as fragmentation.

So the breaking and splitting is done to provide data in the small packet frame in the rightful manner.

We use the existing available resources for it to send the data.
