Hi , Jensen ..

I checked as per your idea. 

I did not get the ""flow-node-inventory:current-speed": 0," in my flow !. I simply launched ODL, installed openflowplugin ,mininet running .

Except this i am getting everything? May i know the reason?

Thanks,

-Karthik

plz check the data which i got ..

{
  "nodes": {
    "node": [
      {
        "id": "openflow:1",
        "node-connector": [
          {
            "id": "openflow:1:1",

Hi Karthik,

In current implementation, you can get rate of speed (both current speed and maximum speed) from opendaylight-inventory. After installing openflowplugin, you can send a GET request to the url http://localhost:8181/restconf/operational/opendaylight-inventory:nodes to get a JSON format response.

The JSON response is like this schema:

~~~ json

{

  "nodes": {

    "node": [

      {

        "id": "openflow:7",

        "node-connector": [

          {

            "id": "openflow:7:LOCAL",

            "flow-node-inventory:state": {

              "link-down": false,

              "blocked": false,

              "live": false

            },

            "flow-node-inventory:configuration": "",

            "flow-node-inventory:hardware-address": "6A:13:45:A1:4F:48",

            "flow-node-inventory:current-speed": 0,

            "flow-node-inventory:advertised-features": "",

            "flow-node-inventory:name": "n7",

            "flow-node-inventory:supported": "",

            "flow-node-inventory:current-feature": "",

            "flow-node-inventory:port-number": "LOCAL",

            "flow-node-inventory:maximum-speed": 0,

            "flow-node-inventory:peer-features": "",

...

I think it is enough for your requirement. I'm not familiar with DLUX, so I cannot give more suggestions. If you want to improve DLUX, you can contact DLUX team to talk about more details. I believe they will be happy for your contribution. :)

Best,

Jensen

Hi Team ,

 Myself karthik , working in ODL.I have a questions. Please help me!.

When I am giving iperf or ping between two hosts , I need to check the network speed (rate at which data is traveling) in each link.For example you could see the ONOS UI , It will show you the data speed in each link.

So I think In ODL DLUX-UI we dont have that kind of stuffs. I would like to develop that. I need your help. From where can i get the details of rate of speed? L2switch or OpenflowPlugin project or anything else? Give me some idea I will do it.

Thanks,

-Karthik
