TCP Fragmentation
Identification:
=========
When any packets are fragmented then it gives some identification number to all packets
So that receiver can identify these as one packet,
Fragment offset: F_Offset= (datagram/8)
============================
When any packets are fragmented then every packet calculates its own fragment offset number
At the receiver end it will identify packets based on IDENTIFICATION number and will put them in order using FRAGMENT OFFSET.
| sequence | Identification | length | More fragment | Fragment Offset |
| 0 | 100 | 1500 | 1 | 0 |
| 1 | 100 | 1500 | 1 | 1500/8=1st frag (datagram/8) |
| 2 | 100 | 1500 | 1 | 1500/8+1st frag=2nd frag |
| 3 | 100 | 1500 | 0 | 1500/8+2nd frag=3rd frag |
