Re: [GENI-ORCA-USERS] hardware openflow

[Deniz Gurkan]

CC'ing geni-users in case people are interested (most of the students may be subscribed to that list).

I am wondering, how did you partition or slice the resources on the hardware OF switches? And, the blog ends with one link per slice - can you elaborate on this? 

Thanks.

Deniz

Yep, I understand that it won't work now, that's fine I will go through Flukes to test it.

My question was more hypothetical, about when this is fixed if this is how an rspec would probably look like on the EG side.

We are adding this functionality on a new tool and we want to make sure that what we put there now
will probably be complaint with all racks. 

Thanks,

Cool! I will try it out.

It looks like the openflow controller is a property of a link, so if we were to port this to rspecs we would have the openflow controller as part of a link, Something like this:

<node client_id="VM-1" >
     <interface client_id="VM-1:if0"/>
   </node>
   <node client_id="VM-2">
     <interface client_id="VM-2:if0"/>
   </node>
   <link client_id="lan0">
     <openflow:controller url="tcp:10.10.8.71:9000" type="primary" />
     <interface_ref client_id="VM-1:if0"/>
     <interface_ref client_id="VM-2:if0"/>
     <property source_id="VM-1:if0" dest_id="VM-2:if0"/>
     <property source_id="VM-2:if0" dest_id="VM-1:if0"/>
     <link_type name="lan"/>
   </link>

Would that be able to be translated to NDL, or that does not match exactly?

Thanks,

You can currently do this via Flukes on UCD, RCI or TAMU

The functionality is relatively rudimentary. Create a broadcast link, attach a few nodes to it, then in ReservationProperties window specify that this is an OpenFlow reservation and fill in the details for your controller (which you presumably start outside the slice). Hit 'Submit'

Hi,

I think with ORCA 5, I could now request  a slice that uses the hardware OpenFlow switch.
is there a site that supports this now and what would be the process for getting such a slice.

Thanks,
Niky

Hi Deniz, 

Picking this up again. To the best of my knowledge, EG uses FV to slice the resources of the FW switches. They are not necessarily using FOAM, but ORCA talks directly to FV (EG folks feel free to correct me here). 

I am guessing that you can only have one link that is OF controlled, although in Flukes you make a whole experiment

OF so I am not sure how that works. Ilya? 

BTW, I have tried this in Flukes (2 VMs, one link) and works like a charm. 

Cheers, 

niky
