What is the maximum number of fragments that can result from a single IP Datagram? Explain.
To fragment a datagram for transmission across a network, a router utilizes the network MTU that is Maximum Transmission Unit and the datagram header size to compute the maximum amount of data which can be sent in each fragment and number of fragment which will be required. The router than creates the fragments. A datagram cannot be larger than the MTU of a network over that this is sent. If a fragment ultimately reaches another network which has a smaller MTU then fragment is further separated in smaller fragments. IP does not differentiate between sub fragments and original fragments. Therefore the maximum number of fragments from a single datagram will depend upon size of datagram and MTU of the networks over that this is sent along its path.
