It looks like Google is getting more comfortable with the world of software defined networking (SDN).

The internet giant said today it is opening up some of its network configuration models to move things around a bit faster.

Google network architect Bikash Koley wants more SDN adoption at the transport layer. To that end, the company has shared its multivendor optical terminal configuration model to the OpenConfig project.

Koley told a telecom event in Chicago yesterday that the optical models will be followed up with other configuration models at the beginning of July.

And to get the transport layer to look more SDN-friendly Koley said, topology configuration has to be vendor neutral, so that system admins can push a centralised declarative configuration into the element management systems provided by vendors.

He also highlighted network state visibility as a key requirement to help SDN better integrate in the transport layer.

As well as Google, there's Apple, Microsoft, Facebook and Yahoo, along with carrier members AT&T, British Telecom, Comcast, Verizon, Level 3 Communications and Cox.

The project uses Yang for its data modelling, with some of its models published at GitHub. The Google models aren't open sourced yet-– they're only available for OpenConfig members to use, for now anyway, but this could change soon.

Other recent work at OpenConfig includes new BGP and routing policy models that went live on June 5th on the project's public repository.
