Fragmentation and Reassembly
Please refer:
http://www.sfc.wide.ad.jp/soi/class/99007/materials/pdf/ch5.pdf#page=16
Each network has some MTU
Strategy
fragment when necessary (MTU < Datagram)
try to avoid fragmentation at source host
refragmentation is possible
fragments are self-contained datagrams
use CS-PDU (not cells) for ATM
delay reassembly until destination host
do not recover from lost gragments
Example
