implement IP TCP Layer in FPGA

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
