Re: [nox-dev] RES: Messenger

Hi Alexandre,

If I understand you right, you are looking for a C/C++ based client
for jsonmessenger?  I know the NOX side is a server side socket, but
the code should be similar.  Unfortunately, I do not know of any C/C++
client for the jsonmessenger.  Anyone who does can chip in.

KK

Hi, thank you for the answers.
Alexandre, as KK suggested instead of looking in the build directory I
searched in the ~/noxcore/src/nox/coreapps/messenger directory and there you
can find jsonmessenger.cc, messenger.cc, messenger_core.cc, and others. Hope
it helps you.
Thank for help me.

[nox-dev] RES: RES: Messenger

[Alexandre Passito]

Hi KK,

Sorry, I mean another application written in C/C++ instead of nox-gui and
nox-console that are written in python.  I already tested these python apps
and trying to speed up thingswith messenger in case some app in C++ exists
in NOX (destiny or zaku).

Regards,

Alex

Hi,

Ricardo, are you looking at the build directory?  Try the source directory.

Alexandre, nox-console and nox-gui communicates with jsonmessenger.
nox-gui can only be found in the destiny branch.  And nox-console is in
src/utilities.

Try to get the doxygen documentation, I tend to write things there.
Sorry, personal habit.

Hi All,

 

I was also looking for some application implemented using C/C++ similar to
nox-gui or nox-console (already understood) that communicate with
messenger/jsonmessenger  but I could not find it in the nox code.  Am I
missing something?

Hi all.
I would like to use Messenger component to send a message from a host to Nox
and from Nox to a host. But the directory messenger has only the following
files:
-messenger_core.la

-jsonmessenger.la

Doesn't exists any C++ or Python messenger component as example or I have to
install / configure it? I am using VMWare and Nox 0.8.

Re: [nox-dev] Mapping flows to queues in openflow switch using NOX controller

[Anand Bawiskar]

Hi Murphy,

I could get the flows matched to queues, didn't try the patch you gave
though.

But I am facing issues in testing it with Iperf, please see if you can help
me:
1) My topology has 3 hosts and 1 switch. H3 listens on udp ports 5000 and
6000.
   H2 and H1 send traffic on 5000 and 6000 respectively at 500 Mbps. I am
using the software based siwtch
   provided in the openflow reference distribution
OpenFlowTutorial-081910.zip
.
2) I added following queues to switch:
dpctl add-queue tcp:localhost:6634 3 1 3 ==>  i assume this makes q1 = 3Mbps
for port 3
dpctl add-queue tcp:localhost:6634 3 2 7===> q2 = 7Mbps for port 3

2) I can see the flow entries were configured appropriately in the switch
using dpctl.
3) I can also see that the number of packets matched for these flows is as
desired.

When i see the results of Iperf, i can see the server bandwidth report shows
it recieves traffic at 160 to 180 Mbps
from H1 and H2 each. I am not sure what is the maximum bandwidth that port 3
supports but i tried values like
100,200,300,400,500 Mbps and see the cieling value at around 400 Mpbs.

Am i using wrong test scenario? Is there a way i can set the value for port
3 to a ceiling value of 100 Mbps?
Is queuing mechanism supported on openflow software switch present in
OpenFlowTutorial-081910.zip?


Thanks,
Anand

Re: [nox-dev] Query regarding routing protocol

[Martin Casado]

afaik this isn't possible today.  However a patch to return the K 
shortest paths would be fantastic.



Hi,

I am trying to modify that routing protocol implemented in the NOX controller to
obtain the second shortest path.

Is it feasible to obtain the second shortest path, such that, the flow
corresponding to the shortest path can me removed and the new flow be installed?

Ramya Subramanian

Re: [nox-dev] Issue regarding setting up Controller (Virtual Testing Environment)

[kk yap]

I see the errors on the switch side, but what about the NOX side?
What is the controller saying about the switch?  Is the switch
disconnecting or is the controller disconnecting the switch?  That's
critical for understanding what is happening.
