Hi Swarvanu,
AD-SAL models, apps and plugins are aimed on OF-1.0. Extending them in order to support OF-1.3 is one possible way. The other is to migrate third part app to MD-SAL API.

Could you share your usecase a bit? Is it necessary to add table id into AD-SAL? Would it be unreal to migrate the app?

Thank you.

Hi Michal,

We are trying to write a plugins for basic network visualization (quite like VNP (Virtual Network Platform) by NEC). We have developed the plugins in ADSAL, and we are using mainly Forwarding Rule Manager to install the flow.

By specifying rules in Multiple tables gives us the freedom to do multiple operation in a single rule. Like putting/stripping vlan id and forwarding packets to specific port etc.

I'm not sure how I could use MDSAL api from a ADSAL plugin. Is it even possible ?

But as per ADSAL I think the table id specification should be there, as it should support the OF 1.3 specification even if we have MDSAL as an alternatives. I'm not sure but I think otherwise we have to move our whole plugin in MDSAL.

Thanks and Regards,
Swarvanu Sengupta

Hi,

I had another query related to the Table Id Specification.

Currently Flow Manager and Flow Programmer Service doesn't really care about what type of plugins is used underneath. I that case the API set should be uniform (currently how it is).

Now table id specification is mainly a OF 1.3 feature. So in that case what will be the API and how its going behave with other plugins for other switch keeping the uniform API set in mind.

Thanks and regards,
Swarvanu

Sandeep,

if you have a packet capture handy of the controller sending LLDP packet outs
before and after this issue, could you please attach? I know you noticed that only one port was getting a packet out, instead of both.

Hi Swarvanu,

AD-SAL was deprecated in Helium release and will be removed in Lithium release.

So i believe there is no work planned for extending the AD-SAL openflowplugin for OF 1.3.
