Hi Troy 

 

What about a tap? Its also like a port ....Should that be in quantum?

I think the idea was slightly different. We were equating a vif to  NIC
in a physical server. A port was equated to a switch port on a physical
switch. Doesn't necessarily mean they have to be different. But, there
was a reason we used different terminology.  

 

In particular, we felt the vif was something that would continue to be
in the server's domain and managed within Nova. A port was a construct
that is owned and managed by the network service (Quantum).

Quick question: it seems we are calling one end of the virtual wire a
port and the other a vif. Is there a reason to do that? Can we just call
say that that a wire connects 2 ports?

 

Also another interesting network scenario is when there is a wire
connecting 2 ports and you have a tap (for all sorts of scenarios). I
think the semantics of the tap might be  quite basic.

Hi All -

 

I wanted to lend support to this proposal, however I don't think we
should be so quick to say this whole thing is an extension.  

 

We benefit a lot from having a standard capabilities mechanism as part
of our core Quantum API. I like Ying's key value method as well. I think
it's logical, clean and scalable. I propose that basic read access of
"cap" off of our major objects: network, port, interface be included in
our first release.

 

So in summary I would like to encourage us to add:

GET  /networks/{net_id}/conf

GET  /networks/{net_id}/ports/{port_id}/conf/

GET  {entity}/VIF/conf/

 

Each of these would return a list of keys.

 

Additionally Quantum base should support

GET  /networks/{net_id}/conf/{key}

GET  /networks/{net_id}/ports/{port_id}/conf/{key}

GET  {entity}/VIF/conf/{key}

 

Where {key} is the name of either a standard capability or an extention
capability. We can define an error code now to designate a capability
not supported by the plugin. (i.e. 472 - CapNotSupported)

 

Finally we don't need to standardize on every capability that might be
supported if we provide this simple mechanism. Specific capabilities
Key,Value sets can be added later but or included as vendor specific
extensions.

 

I'm happy to add this to the wiki if there is consensus. Rick/Dan -
Maybe this should be a topic for Tuesdays meeting.

 

Alex

Hi all,

 

We just posted a proposal for OpenStack Quantum Service API extension on
community wiki page
athttp://wiki.openstack.org/QuantumAPIExtensions?action=AttachFile&do=vi
ew&target=quantum_api_extension.pdf

or

http://wiki.openstack.org/QuantumAPIExtensions?action=AttachFile&do=view
&target=quantum_api_extension.docx

 

Please review and let us know your comments/suggestions. An etherpad
page is created for API extension
discussionhttp://etherpad.openstack.org/uWXwqQNU4s

 

Best,

Ying
