Hi, 
I want to implement IP and TCP Layer in FPGA.
I don't know if some of you have done something about this implentation.
I need some advice.
What can you think about this project? (the bandwith is 10Gb ethernet).
Thank you
Pierre

Short answer, it is a big project.  A very big project.

IP is fairly easy.

TCP for a very limited list of connections (like 1 to 16) isn't too
bad, as long as the odd cases are ignored.  This can work very well as
long as you only talk to "well behaved" remote hosts over "well
behaved" networks.  Unless you need to send a lot of data, a local CPU
with a network stack is probably a better choice.

Full TCP, at wire speed, with hardware to handle most of the odd
cases, is very hard.  Will require lots of gates, lots of internal and
external memory, lots of simulation and testing.

I believe 4links in the UK implemented a product like that, do a search for 
4links+TCP+FPGA and you will find the press releases,
