What if you always had ESP (RFC 2406 for you fellow old-timers taht are
thinking back to our college days :). How would TCP change?
First we would drop the CRC checksum. All of the ESP auth methods are much
But what about sequence numbers? ESP has a seq # also. Can it be used in
place of TCPs? What restrictions need be placed on ESP's seq #?
Why do I ask, you ask? Well I have been concentrating on good, end-2-end
ESP with a new Key Management Protocol called HIP. And since I am already
recommending changes to the TCB API (use a hash of the Host Identity in
place of the IP address to decouple the internetwokring and transport
layers), and since I want this to be very wireless friendly, I am looking
at what I can do to 'compression' TCP's overhead.
