Why are these datagrams reassembled to single datagram

Question

Where are these little datagrams reassembled to a single bigger datagram? So While a broader datagram is broken into many the smaller datagrams?

Summary

In this question, we will have little datagrams reassembled to a single bigger datagram while a broader datagram is broken into many smaller datagrams. And if the packet size is very big to send by a physical link. Then it will be divided into parts. So then the bigger datagram will get into the smaller datagram. And after that, the smaller datagram is sent. So that datagram is them reassemble when they reach to the destination. And they are reassembled with the help of the identification number of each datagram.

Explanation

• • Sometimes the packet size will be very big to send by a physical link.
  • So in that time they that bigger packets are divided into smaller packets.
  • And This is the process of forwarding IP fragmentation.
  • So The smaller datagrams are then called as the IP fragments.

• • But that bigger packets are not sent directly. They are divided into smaller one
  • And that small packets are then send individually. One at a time.
  • Once all the packets are reached to the destination they are reassemble.
  • And they are reassemble with the help of identification number, addresses of source and destination attached to their IP header.
  • Once they are reassemble the receiver will check them. By checking their identification number. And will check if they are properly reassembled or not. Hence, all those datagrams with same identification will be reassembled to get the initial bigger datagram.
  • And in the last they all create a large datagram into the packet. That means the file that is supposed to send.
