I did a prototype for that by modifying the lldp app.
I did work as a proof of concept. One bad thing is that the measurements
are not really reliable.
I've also seen papers of people doing the same thing with other controller
so it should be possible. Just understand that make it reliable is a g
Thank you so much for the reply.
The curr_speed value is set to 1000 and the max_speed is set to 0. Is
this correct.
This seems to be the port speed. What I am interested in is the link
bandwidth. How can I get that ?
Along with this,I want to know the link status. How can I do that ?

hi,
afaik, there's no existing ryu apps which do that.
just an idea:
a. controller-switch latency can be measured using echo requests.
b. controller-switch-switch-controller latency can be measured using
packet-out/in.
(b - 2 * a) might be what you want.

hi,
ofp_port has curr_speed/max_speed fields.
they might be what you are looking for.
see OpenFlow 1.3.4 p.49-50.

Dear All,
How can we get the link bandwidth in Ryu app. Is there any message from the
switch that gives the link bandwidth.
Thanks,

Hi,
I attempt to work at QoS experiment and Monitor the network resource in RYU
controller. However,I don't know how to measure the link delay in RYU. Does RYU
support to measure the delay for every link ? How should I do ?

hi,
there are two ryu-stuffs in openstack. ie. ryu-plugin and ofagent.
i'll assume you meant the latter. (because the former is being deprecated)
devstack is the easiest way to install. [1]
you have nothing to do manually with ryu cli etc.
there's no easy way to see the physical topology.
(the lo
i guess you edited a wrong copy of the module.
please check your python module loading path.

Hi, teacher,
I am very honor to write to you. Now I have some opnions about BGP
service.
1. Because BGP peers connect to each other by TCP in port 179, so we think that
a flow can be created that packets(update, open, notification, keepalive)
matching tcp:179 shuold be sent to controlle

Hi,
You seem to use master branch of devstack.
Can you try stable/juno branch of devstack?
devstack$ git branch -r
origin/HEAD -> origin/master
origin/master
origin/stable/icehouse

Dear all,
I couldn't find an elegant way within Ryu to open a socket and listen to it
within my application. At the moment, I am spawning a new thread from my own
app and using select over the socket file descriptor. Is there any other
(better) way of doing this? I was thinking something like
Hi,
Thanks for your answer.
But the weird thing is that I still get an error. And even if I get a
confirmation that the flow are added they are not present...

Hi, as I know, ofagent project had been separated into
networking-ofagent
(http://git.openstack.org/cgit/stackforge/networking-ofagent/).
Try to load it with Devstack enable_plugin directive.

Hi,
I tried to reinstall ryu with devstack but I get always the same error.
You can see my output in this attached file .
