Where in the TCP/IP protocol stack does compression occur?

OSI Protocol Stack
TCP/IP Protocol Stack.
Quite happy to bear with you but you do not want to see me with my clothes off ;-)
That would assume the end-user applications were aware of data compression. What if this wasn't the case? Would compression not occur?
On aside, I believe there is an error..... `Network,' should read `internet,' not to be confused with Internet.
;-) Will watch my typing in future.....
When you talk about TCP/IP stack you normally are not talking about the Application level. Just the Transport level. That's why I say there's no compression in the TCP/IP stack, because the Application level don't use to be considered part of the TCP/IP stack.

With a dial-up connection (and certain others), the link layer is PPP: (ftp://ftp.rfc-editor.org/in-notes/std/std51.txt). PPP includes a limited form of compression.
Why is this of interest, anyhow?
I'm currently examining IPsec.
If encryption is used, then compression is not possible.
I'm also interested in any potential performance gains (smaller packets ->
faster [IPsec] encryption... but at what overhead? Smaller packers should also improve performance elsewhere)

You compress the data before you encrypt it.
compress decompress encrypt decrypt send() -----> recv()
Sorry, I thought I had already implied that in my last post.
Yes, it is possible. BUT, can performance gains be achieved by doing it?
(Security is also increased by compressing then encrypting)
If you consider that part of the TCP/IP stack is right.
