Thanks Justin,

Is there a document/sources for that daemon?

Hi,

In his April talk at Usenix (https://www.usenix.org/sites/default/files/conference/protected-files/nsdi14_slides_koponen.pdf),
Teemu Koponen mentioned a replacement protocol for OF & OVSDB for network virtualization.

Is there any further information/specification/implementation of the protocol?

Teemu is proposing that there may a application-specific protocol that speaks down to the hypervisor.  There a daemon understands this other protocol and acts as a local controller that speaks directly to the vswitch using OpenFlow and OVSDB.  While there are plenty of fair criticisms of OpenFlow, it actually turns out to be a pretty good way to model a software switch, since caching becomes (relatively) straight-forward.

What does it mean for the roadmap of OVSDB in Open vSwitch?

As I mentioned above, that paper/presentation doesn't assume changes in OVS, and, in fact, leverages OF and OVSDB.
