Default Ethernet and TCP/IP proto in vhdl

Hello there

I'm looking for some implementation TCP protocol in VHDL language.
Maybe some software have all ready modules for Ethernet standard?
I want to get on that level, when I can get statistic information about
some packets.

Best regards.

If I'm not mistaken, TCP is not handled by hardware, ethernet is. So
you will not find VHDL implementations in VHDL.

Check out www.opencores.org for an ethernet implementation.

You are mistaken, there are VHDL implementations but as far as I know no
free ones, see the one below from 4links in the UK,

"Other engineers like the concept because, as hardware, it can easily be
verified and should be more secure than software. "

Pish-posh!

Thanks for putting that right. I should have googled before posting:

A very recent (August 2006) implementation:

Maybe it boils down to a culture difference between sw and hw developers.
Burned boards tend to make the penalty for mistakes higher.. , and you can't
apply patches "later"..

Thank you for response
