Hi guys,
I have successfully installed a Virtual Machine containing NOX and Mininet.
Following the walkthrough I was able to transform an HUB to a learning
switch.
Moreover I premit that I've well understood how components are linked by
mean of "meta.xml" files,
Now I'm trying to use the "sampl
t?
My main objective is to be able to define and deploy custom paths for flows
in the network .
Thanks a lot

end-to-end delay. (I don't need to estimate the switch-controller delay, but
simply look at the two timestamps provided in event notifications).

Hi guys,
I've recently installed "NOX 0.9.0 zaku", and I'm looking for the
"nox-guy.py" file.
The noxrepo page says it' s under the /src folder, but there is nothing.
Maibe the gui is not available in my NOX release?
Any suggestions

I solved the problem by running the following
./nox-gui -p 6633
./nox_core -i ptcp:6633 sample_routing
Now everything seems being working :)

Hi Karim,
I ran *'nox-new-c-app.py miocomponente'* , and the result was a

about its construction:

switch (very bad behaviour).
Any suggestions?

Hi guys,
I've a simple question: "What happens when a component has to handle
multiple instances of the same event? "
Each event instance is handled in a FIFO manner, or multiple threads of the
same handler are instantiated?
Thank you

In such a way the system in kept synchronized, and the system works
properly.

Hi guys,
How I can setup component priority over events? i.e., If I have 2 components
registered for packet-in events, how I can decide their priorities?

Hi guys,
I'm writing a C++ component that needs to access the TCP sequence number of
a packet upon packet-in-event notification.
Is there an high level function that simplifies such task? Or I have to take
an offset after calling the get_buffer() function from the event?
Thank you.

It's correct? What is the correct "ofp_action_header []" parameter to pass
to the function?

Hi guys,
Does the process waiting for OF messages on port 6633 instantiate a new
thread for each new incoming message? Or messages are handled in a
sequential manner?

Hi Vishal,
is the OpenVswitch an implementation of OF 1.1? I'm running NOX 0.9.0 zaku,
is it compatible with such version of OF?
