In the ISO connection-less network protocol (ISO8473) one function is
Route Recording. I have only an old copy (DIS version) at hand, and my
question is if the following text is still valid, and if my interpretation
is correct:
  "When Complete Route Recording is selected, PDU reassembly at _intermediate
  systems_ is performed only when the Derived PDUs that are reassembled all
  took the same route; otherwise the PDU is discarded, .."
Now, reassembly is normally performed in the final _end system_, not in the
ISes. My interpretation of the text is that no restriction is posed on
reassembly in the _end systems_. An ES may perfectly well reassemble
fragments which have followed different routes.
Also, the point of discarding (in an IS) fragments which followed different
routes, is only valid if the IS really does reassembly. If it just passes
the fragments on, no error occures.
Comments, anyone - by E-mail if this is not considered to be of general
interest.

Thanks in advance.
