I wrote inet (the TCP/IP stack on MINIX) for two reasons: I like to come upwith my own designs for everything and, most of all, I had to impress AndyTanenbaum enough to become a Ph.D. student. Inet had to fit in with MINIX. Inparticular, it had to live with minimal changes to the MINIX code base. At thesame time, there were quite a few areas where I felt sockets and the BSDTCP/IP implementation were wrong. In hindsight, there is a lot that I did not know and got wrong. I this talk, Iwill look at how inet follows the structure of MINIX, what works, and whatwent wrong.
