That's true: I think Altera has chosen the Interniche stack because they
get support for it and don't have to do it on their own. Also, the
Interniche stack has some upper-level protocols which are not included
in lwIP (since lwIP focuses on the TCP/IP part of networking, not the
upper-level protocols). But from what I can say (I evaluated the
Interniche stack after Altera moved to it), I think technically, there
is not that much difference: the only things I saw Interniche supports
and we don't (YET!) are IPv6 and checksum-on-copy (which is under
development in lwIP and I can't even remember if it was the Interniche
stack which supported this...)
Anyway, I have to admit the lwIP stack has a hard time against the
Interniche stack with Altera products, because you get the license for
free when you buy Altera products and it is better integrated into the
Altera IDE (Add-ons for Eclipse). But if you don't mind writing a bit
more of your own code instead (to make up the
Interniche-IDE-integration), lwIP is still a good competitor, of course!
-> That's why I use it!

With a bit of digging, it appears to me that Altera farmed out the
stack porting/maintenance task to interniche tecnologies, inc. -
TCP/IP networking is not Altera's core compentency so I can understand
the move. Now they don't have to worry about keeping up to date or
supporting issues with the stack software.

*Subject:* [lwip-users] Choosing lwIP
Folks…
I’m looking into TCP/IP stacks and am very interested in lwIP.
However, on the Altera website, they do not recommend lwIP for new
development because they said it is legacy, or deprecated. Is this
true? Does anyone out there have any ideas of why they would say this?
Does lwIP have support for IPv6? Could this be the issue? And if lwIP
does not currently support IPv6, what is the schedule for developing
such support? Or, are there other technical capabilities lwIP does not
support that commercial solutions might?
Thanks in advance for any thoughts.
…Stacy
