Technical Summary

   This document discusses issues with fragmentation in today's Internet.


   The 16-bit IP identification field is not large enough to prevent
   frequent incorrectly assembled IP fragments, and the TCP and 
   UDP checksums are insufficient to prevent the resulting corrupted
   datagrams from being delivered to higher protocol layers.
