Re: [nox-dev] Hosts with Same IP

2010-11-19 Thread Nikhil Handigol
Hi Rohit,

I lead the Aster*x project at Stanford. What you want to do sounds very
similar to Aster*x.

Aster*x, formerly known as Plug-n-Serve, was demonstrated at Sigcomm 2009.
You can find the abstract and video at:
http://www.openflowswitch.org/wk/index.php/Videos#SIGCOMM_demos

A couple of weeks ago, we had a major demo at GEC9, where we demonstrated
Aster*x working across 9 US campuses. The abstract is up at:
http://groups.geni.net/geni/wiki/Gec9PlenaryDemoAbstracts
The video will be up online soon.

I hope you find this useful for your project.

Cheers,
Nikhil

 HI Rohit
 I'm not sure if this is a question appropriate to the nox-dev list. I
 believe the list is intended for questions regarding developing over
 NOX.

 You may want to lookup a previous work called Plug-n-serve, followed
 by an improved system called Aster*x, that builds a server farm with
 all hosts having same alias IP address, while having different MAC
 address. To achieve what you are suggesting, you might have to rewrite
 MAC addresses at the gateway point instead of trying to use ARP
 revocation to change the MAC address for each request.
