      - Fragmentation is a state that occurs when data passes over networks.

      - The fragmentation caused by a small packet network is made transparent to network through which the packets will pass.

      - The main disadvantage of fragmentation is exit gateway, all the packets should exit via the same gateway.

      - It required overhead to repeatedly fragment and reassemble a large packet.

      - When a large packets arrives at a gateway, it breaks the packet into fragments.

      - Each fragment is then addressed to the same exit gateway.
