IMHO: IETF is only partially guilty. Who was capable to predict in
1992-1994 that:
- Wireless would become so popular (WiFi is from 1997)
IP mobility WG of IETF was formed in 1992.
- Hardware forwarding (PFE) would be invented (1997) that would have
a big additional cost to implement Enhanced Headers
Optional IPv4 headers was considered harmful, IIRC before 1992,
which has nothing to do with TCAM.
- Encryption would never have a small enough cost to make it
mandatory
Cost of encryption is small enough. The problem is to securely
share keys, for example, between a source and a router to let
the router generate secure ICMP.
- Router would be available in every smallest thing that makes
distributed address acquisition redundant (hi SLAAC)
Local router is always available for a network with two
or more links, which was why SLAAC were a good idea.
We should be fair
You should.
