Deciding Upon a Collaboration Solution: Do Open Standards Still Matter?

While I was participating in a web conference from my home office, I started thinking about how much and how fast things have changed in the last decade around communications and how we use collaboration tools in the office, at home and on the road and most importantly the number of devices available to me so I CAN collaborate over distance.

One thing that stays constant in this industry is change, especially when it comes to devices. Let’s take a walk down memory lane and see if you can remember any of these once “have to have” mobile devices. The Nokia 9000, The Motorola “Flip phone” and The “Razor”, Palm Pilot, dare I say the Blackberry and of course at the start of 2007 the IPhone came on to the market — and we all know how that is playing out — this being a rarity. More recently, Samsung is challenging Apple with the Galaxy and DROID OS is becoming more prevalent than IOS. Last I checked, there was an estimated 1.3 million Read More »

Making a Case for Programmatic Interfaces in Existing Service Provider Networks – Going Beyond Software Defined Networks

The communications industry has come a long way from fixed, inflexible telephone service optimized for voice to dynamic IP-based connections offering converged voice, data, and video capabilities. Now, both residential and business users are increasingly more mobile and distributed, as are the cloud-based services, applications, and content they want to utilize. Service providers must therefore support a more diverse customer base with more distributed content and applications across multiple geographies, yet still maintain a secure, reliable, and consistent quality of experience regardless of device and physical location.

In the face of greater traffic demands and the risk of becoming lower-margin “commoditized pipes,” network operators must react to three key challenges: Read More »

OK, Now What?

 “Each success only buys an admission ticket to a more difficult problem.”

— Henry Kissinger

Following the early successes with network programmability,  the natural question that arises is “where do we go form here?”  Certainly some good things have been accomplished, but in many ways the real work is just beginning. David Ward just posted some musings on where we go next with programmatic interfaces for the network–its a good read and I encourage you to check it out.

What Comes Next with Cisco and the ONF?

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.

2010+ networking software: how to open up, how to speed new ideas to market

The onePK announcement Ric describes in the previous blog entry is game changing. It also intersects a trend which has gone fairly unnoticed in the networking standards areas. The importance of new standards is declining relative to advances in software and hardware. Read More »
