2)I'm sure I'm late to the game on "virtual-port" discussion but I
see in
OpenFlowMPLS, OPEN-MPLS, and the v1.2 proposals page that there is
the idea
of adding the ability to create virtual-ports. Is this going to be
in the
next version of OpenFlow?
Just to clarify, the OPEN-MPLS work does not add virtual ports to the
switch.
There is a concept of virtual-ports that signify tunnel-interfaces for
MPLS-TE tunnels.
But it exists only within the controller to make life easier when
implementing TE features.
The switch (OVS) is completely unaware of the existence of tunnel-
interfaces and virtual ports
and treats MPLS like any other flow (as per OF1.1).
One way to think about it is that the controller 'layers' a virtual-
port abstraction on top of the switch's flow abstraction
