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

    - The fragmentation caused by a small packet network is made transparent to the 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 requires 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. Because of fragmentation there may be chance of a DoS attack.
