Towards OpenFlow 0.9

September 21st, 2008, Guido Appenzeller in OpenFlow Blog

The OpenFlow v0.8.1 spec was released way back in May of 2008.  Since then, a number of vendors have joined the OpenFlow Consortium.  These implementations have identified a number of areas where the current OpenFlow spec is underspecified, inconsistent, or missing useful features.

Thanks to Justin, Ben and Brandon, we are nearing the release of OpenFlow 0.9, which will fix many bugs and provide a number of new features. Our hope is that OpenFlow 0.9 will contain all the features desired for the big OpenFlow 1.0 release, and only small changes will be described in 0.9.X spec releases.

Some of the most important new features include:

  • Vendor extensions. This is necessary to keep 3rd party implementations of OpenFlow backwards compatible while allowing vendors to implement features they want to test.
  • Better capability reporting.  Now a switch reports the features and wildcard fields it supports, for each table.
  • IP subnetting support.  This enables OpenFlow switches to act as IP routers on some commodity switches.

For a more complete list of the proposed v0.9 changes, take a look at the 0.9 release notes draft on the wiki.

OpenFlow at the POMI retreat

Today we presented OpenFlow at the POMI off-site. POMI 2020 is a new major research effort at Stanford that is exploring how the wide proliferation of powerful mobile devices will change networking, computing and applications. POMI involves about 15 Stanford faculty from electrical engineering, computer science but also other fields such at education.

One of the major challenges of future mobile networked devices is that the current IP based infrastructure does not offer good support for either security nor mobility, and OpenFlow offers potential solutions with POMI and Ethane type solutions. OpenFlow will be one of the major initiatives inside POMI and we are excited about the potential collaborations.

As you may have noticed, the OpenFlow Switch Site has a new logo. It was designed by Worth1000 user NoxCiepher.
