   "TCP/IP illustrated", volume 2. Or any of the stacks implemented in OSes   
   whose source code is available (I suggest to read the book first though,   
   because it's thoroughly commented and explained).

   It isn't. FTP uses TCP, which treats data (from the application point of   
   view, at least) as a single stream. If you're talking about lower levels,   
   fragmentation basically depends on the link MTU (much simplified). IP is   
   the protocol that handles fragmentation and reassembly. The process is   
   documented in RFC 791 for IPv4 and RFC 2460 for IPv6.
