Hi,

version 1.0 of the widely used uIP embedded TCP/IP stack is out:

                   http://www.sics.se/~adam/uip/

This release adds rudimentary IPv6 support (TCP over IPv6 works, pingv6 
works, neighbor solicitations are answered; tested only against FreeBSD 
6.0 howver), as well as a number of other features and bugfixes. There 
is also a new mailing list for uIP users. Instructions on how to join 
the list is available from the uIP homepage.

Best regards,

/adam

Hi Adam, 

Interesting news and good activities...

Quick question;

[1] 6lowpan basic solution as SubIP layer is 
embedded into the uIP stack ?

[2] What you mean by the sentence below ?
"neighbor solicitations are answered"
It implies IPv6 ND Optimization or anything else ?

Regards.

Hi!

> embedded into the uIP stack ?

No, uIP only includes the IP layer and above.

> It implies IPv6 ND Optimization or anything else ?

I basically mean that uIP only does the minimal ICMP processing needed 
to get communication working: it sends neighbor advertisement messages 
in response to incoming neighbor solicitation messages for the currently 
defined IP address (uIP only supports a single IP address for now). uIP 
does currently not even send neighbor solicitation messages for 
addresses that are not found in the neighbor list. So it is a very 
rudimentary IPv6 implementation in this respect.
