You probably missed this... In the link you attached

"The latest version of LAVI uses a JSON backend, which has to be

Hi Andrea,
In flow.cc, the flow struct is defined and that is used to parse the
packet-in content. You can get the seq number for tcp_header which is
described in packets.h. It should not be hard to parse this, since
the packet is parsed for the various headers already.

Hi,
Murphy and Andrea are right. The structure is designed to store a
tree, thanks to my need for a "multicast" tree in OpenFlow. So, it is
the output and reference to the next switch and the corresponding
input port at the next switch.

Hi Christian,
I need to take a deeper look to give any constructive comment but your
use of auto_ptr should be at fault. This can be a memory allocation
problem. As Murphy hinted on, you might want to use the facilities
available in NOX to help rather than write everything on your own.

Hi,
This is a standard procedure in NOX. You need to include the header file
for the definition of the event, then create the event, populate it and post
it. One of the lavi component (though I forgot which one) will listen for
that event and send a message to ENVI. Look at lavi_hosts (I think)

might be advisable not to cross-post questions.
To be clear, LAVI is a GUI backend in NOX. And nox-gui.py and ENVI
are the front end GUI.

OpenFlow 1.1 (implemented) is released, so it is quite final for me.
Also, if you are not constrained to using the group semantics (in
OpenFlow 1.1), you can do multicast by listing all the ports you want
to multicast to in the flow_mod command.

Hi,
A "quick" overview of NOX was prepared for a class in Stanford. These
slides are made publicly available via GoogleDoc
(http://tinyurl.com/noxreview). These might be useful for those who
want a quick overview of NOX and get started on it. Hope people do
find it useful.

Hi Josh,
It seems like there is quite a bit going on. I am happy to push the
DEBIAN control file and init script. Would you mind creating a patch
based on nox-destiny so that I can have your name on that commit?
Else, I can do it but it is suboptimal that my name is on the commit.
Thanks.

nt, so you cannot resolve
it this way. You should look at Flow_fetcher_app instead.

Hi Paulo,
cc-ing back the list for archival.
It should be resolve(ff) and not resolve (Flow_fetcher). That should
resolve it.

Hi Paulo,
You have not include the flow fetcher's header? Sorry for the wild
guess, but from what you provided this seems like something about
header inclusion.

The Python parsing logic in zaku has a few corner cases that it does
not handle. I would suggest trying the destiny version of this
function.
def convert_to_eaddr(val):
if isinstance(val, ethernetaddr):
return val
if isinstance(val, array.array):
val = val.tostring()

Hi Aaron,
Can you tell us if there is any difference in the tcpdump from the HP
and Indigo?
I skimmed through the NOX code and it seems to parse VLAN. So, there
is something amiss here.

Hi Derek,
I pushed all the patches. I did not realize you are just exposing
things to Python and not declaring new structs. Sorry. A quick
glimpse has failed me.

Hi Vishal,
Any reason not to use the zaku branch? If not, give that a try. Might to
useful to send your config.log.

Hi Anh Nugyen,
I believe this is the size of the OpenFlow message which is carried in a TCP
stream, so you should be able to find it in wireshark (though the size will
be much larger). Wonder if that is what you are looking for.

Hi Ricardo,
Before you adding an event handler ( which is different from adding events
in NOX ), did you run a component that does nothing? Try that. You can
create to a new component using nox-new-c-app.py if you are using zaku or
later. That component should just run.
After which, you can lo
eat. Should I post any future changes here on the Nox board or send
