Hello,I have deployed openflow stanford reference design module on UBUNTU

windows 7 hosts.The basic ping command is working successfully and it is
showing the flows also.I want to to block one of the host's packets(flows

ANyone knows how to generate Traffic in a mininet topology running on VM
with openflow 1.0 running. The controller is a load balancer. Hence we want
to simulate network traffic, with or without using a web browser.

You can install Firefox and use 'sudo firefox &' to launch Firefox, assuming
you have set up X forwarding. For mininet, so far I just installed and use
Lynx. A quick check is to use Python simple web server:
mininet> h1 python -m SimpleHTTPServer 80 &
mininet> xterm h2
Then in h2 use 'lynx htt
Hello,
Is it possible to open a browser inside Virtual box and mininet topology?

Scalability and performance is definitely something I that I believe can be
improved quite a bit, so I encourage more performance analysis and also
contributions to improve the startup speed and overall performance of all of
the components.

Volkan,
Have you tried --switch user also? OVS doesn't start up as quickly, although it
has better forwarding performance.
Also the 1:1 switch:host ratio is probably a bit high for most real networks at
least. ;-)

Hello,
I and my team have designed a load-balancer form a learning switch code,
given in the open flow tutorial. Now, we have created a web Server and
Client code. WE tried to run the Server on putty and tried the client to
be the browser, then it works. If we try the Server running on the xter
Dear Ron
Thanks for the feedback, I will verify your tip, actually I'm testing the
implementation is to be done in NS-3.
He already boasts two implementation, one Drop_Controller and
Learning_Controller.
Thank you!

Dear, good afternoon,
I am conducting research to implement a Load Balance with OpenFlow Controller
simulator NS-3.
The atmosphere is simple, consisting of a client and two servers, where it will
perform load balancing, sending a stream of data to each server, simulating a
Round Robin.
I'm hav
Hi,
I heard that Trema team had also tried to solve a similar issue
(interoperability between Trema and OpenWRT), and they says that
one workaround is to add --inactivity-probe=90 to the ofprotocol
command-line on the switch.
A modified version of /lib/openflow/ofprotocol.sh in OpenWRT
can be
hi Adria,
unfortunately, yes, this problem has been seen before on the Pantou firmware. I
don't know that anyone has determined a root cause.
there are a couple workarounds:
1) have your controller send periodic ECHO_REQUEST's to the switch, rather than
wait for the switch to send them. for ex
I have done logread -f in telnet of the openwrt:
result is:

Hi, I have some trouble with linksys wrt54gl, I have installed pantou

and nox (https://github.com/noxrepo/nox) branch verity.

For those who are interested in, I put together a small mininet benchmark
that measures the memory usage and the start+shutdown time for a linear
topology composed of 1, 32, 64, 96, 128, ..., 1024 switch+host pairs.
