Study Notes
Datagram Reassembly
- Datagram reassembly is the process of creating a copy of the original datagram from its fragments.
- The fragment containing the final data piece has a flag bit set to 0 in its header. This indicates the end of the fragmented data, enabling the receiver to determine if all fragments have arrived.
- Only the final destination host should perform reassembly.
Fragment Fragmentation
- If a fragment reaches a network with a smaller MTU (Maximum Transmission Unit), it may need to be further fragmented.
- Fragmenting a fragment is possible.
