What Comes Next with Cisco and the ONF?

June 28, 2012 at 10:54 am PST

So, goings on with OpenFlow and the Open Networking Foundation (ONF) are always lively topics for discussion.  Since our announcement of Cisco ONE at CiscoLive, a number of folks have asked me if the announcement of our strategy changes our view of the ONF or the role of OpenFlow—the short answer is, simply, no.

We continue to strongly support ONF and its efforts related to SDN and our support has and will continue to been demonstrated in tangible ways.  One of the elements of the Cisco ONE announcement is onePK, which is an enabling technology and one of the things it has enabled is the development of our OpenFlow agents.  Similarly, we have introducing controllers and working with our customers to develop the technology.

What seems to surprise a lot of folks is that our contributions to ONF go beyond our own internal development efforts:

Technology Advisory Group - Chartered to provide high-level guidance on any technical issues faced by the ONF Board in which feedback is requested.

Hybrid Working Group - Document the requirements for a hybrid programmable forwarding plane (HPFP).

  • Chaired by Jan Medved
  • Hybrid Use-cases document: Co-author: Bhushan Kanekar
  • Hybrid Switch Architecture -- Integrated: Co-author Bhushan Kanekar
  • Hybrid Switch Architecture -- Ships in the night: Co-author Dave Meyer
  • Terminology document: Co-authors: Dave Meyer, Bhushan Kanekar

Beyond these two working groups, the Cisco folks, including Jan Medved, David Meyer, Josh Littlefield, Andrew Thurber, Alex Clemm, Mark Szczesniak and Bhushan Kanekar have been active in other workgroups including the Configuration & Management Working Group and the Extensibility Working Group.

Beyond these efforts, David Meyer has been a rock star across the board including contributions to the “OF futures” discussions and recently received an award from the ONF for his contributions.

To net things out, Cisco expects to be a pacesetter with regards to network programmability and SDN and our efforts with ONF will continue to be part of that strategy.

OpenFlow: “Pulling networking into the application stack”

April 18, 2011 at 11:14 am PST

Recently, we announced our participation in the Open Networking Foundation (ONF).  As you may know, ONF is focused on defining a software interface enabling the programming of how packets are forwarded through a switched network as defined in the OpenFlow Switch Specification. Beyond this, ONF is also focused on developing an abstracted software interface that management tools can access.  At the end of the day, ONF is looking to advance OpenFlow and and make it easier for customers to fine-tune, manage and adapt their networks.  In addition to Cisco, the organization includes Broadcom, Brocade, Ciena, Citrix, Dell, Ericsson, Force10, HP, IBM, Juniper, Marvell, NEC, Netgear, Verizon, and VMware.

I sat down with Paul McNab, VP/CTO of the Data Center Switching and Services Group, who is leading this effort at Cisco, to get some answers on what this all means.

Omar Sultan: Paul, many industry pundits did not expect us to do this and their reactions were kinda entertaining. So, why did Cisco decide to do this?

Back to the future: the Open Networking Foundation

Along with several key industry players we announced the formation of and participation in ONF, the Open Networking Foundation with the purpose of promoting a new approach to networking, called software defined networking, open standards based of course, and implicitly open source since all compute loads (or clouds) need and want both, as we are continuously reminded.
