- I beg to differ with Erick's statement that intermediate gateways will
- reassemble the fragments of an IP datagram. It is not the
- responsibility of an IP router to reassemble transit fragments. An IP
- router should be able to reassemble fragments for which it is the
- destination, but not in general. In general, the IP datagrams do not
- always follow the same path through the Internet, so transit systems
- cannot do reassembly. Only the end system can be assured of seeing all
- the fragments.
-
- Fragmentation is good, useful and helpful. Buyers and implementors
- should be sure to insist that their end stations can handle all the
- trickey cases of IP reassembly.
