Hi Abhijit,

With reference to OpenFlow Plugin(Eviction and Vacancy as an extension to Openflow specs1.3)- no further inputs has been received. Hence the changes could not be submitted as per M4 ODL-Be timelines.
Hopefully, we will look forward to this feature submission in ODL-B(Boron release).
Do let me know in case anything is pending from our end.

Thanks,
Gaurav Pande

If Michal is not able to provide the suggestions during his day – hopefully Anil will be able to during the day.

Hi Abhijit,

Kindly provide suggestions for the queries (Please note that some of them are implementation specific ).
If we get the queries clarifications  by tuesday(IST) EOD, We can still target it to complete by Thursday(17th-Dec).

Thanks,

BTW about the #Personal# tag in subject line, Gaurav's company (TCS) policies will not send the email to @gmail.com (Anil & my email ID - its easier for me to search some of the ODL emails on gmail).

Michal, Anil,

Can you guys help Gaurav with his questions?

Gaurav - are you on track for Dec 17 (this Thursday for code freeze) if this gets resolved?

Thanks,
Abhijit

Hi Abhijit/Michal,

Kindly suggest some feedbacks for queries in below mail-chain in reference to the design approach presentation of eviction and vacancy.

Thanks,
Gaurav Pande



Hi Abhijit/Michal,

With reference to the Design presentation, we have the following queries to resolve:
  • Slide #6 (Table-mod message) : Table-mod api is only exposed in Openflow-Java and not in OpenflowPlugin, how can we test the code by hitting the Api for Table_mod message.Which Yang module should we target in OpenflowPlugin for implementing Table-mod. Also How to implement openflowjava apis in the openflowplugin.
  • Slide #6 (Table-mod message): In which yang module we should define table-mod-prop-vacancy. According the discussion with ovs team this property-type-vancancy gets concatinated with table-mod message while triggering vacancy events. So should we treat it as a different message or should we augment it with table-mod message.
  • Slide #7 (Table-Description message) :  Table-Description is a new message, and we have defined the yang in OpenFlowJava (openflow-protocol.yang). We need to know how can we implement it in OPenflowPlugin, so as to trigger it from the apis.
  • Slide #8 (Table-Status message) : Table-status is also a new asynchronous message.We Needs to set the ofp-asynchronous-config table-status field to tell the switch to send table-status message, but for testing purposes we have set the table-status message by default on from switch side(so no need to set notification and other changes from controller as of now). We need to know here that how to support the asynchronous messages from OpenFlowPlugin.


Thanks,
Gaurav Pande

Thanks for the slides Gaurav! Its good progress. I think we need to have a slightly longer discussion – if we are not able to resolve this over the mailing list then we will need to continue the discussion next week’s meeting (unless we manage to have a small mini session with you and Michal or Anil is a time friendly to your timezone).

Hi Abhijit/Michal,

Please find attached document for the Design approach for Eviction and Vacancy. The queries are marked on the last slide.
There were some serious audio connection problem from my side as I was not able to hear clearly. So if I had missed anything from the audio, please let me know.
It would be great if we can discuss this more again some time later with your suitability.

Thanks And Regards,
Gaurav Pande
