Nobody said TCP/IP was perfect, or the end of the world. There are 
constantly new problems to address.

However, OSI was not the solution then, and is not the solution now. I 
don't see anyone trying to dig out that old corpse.

The problems that named data tries to solve are very much centered 
around better use of bandwidth. Lots of the other stuff in there follows 
from that initial problem they are trying to solve.
