Enterprise SDN: Moving from box boundaries to software boundaries

November 1, 2012 at 7:10 am PST

Enterprise trends driving SDN and Network Programmability are becoming clearer.  The skyrocketing number of virtual/cloud devices is making human configuration infeasible.  A natural result will be that networks will move from being integrated based on physical box boundaries to being integrated based on software boundaries.  Put another way, traditional box based network integration will be overwhelmed by device proliferation.  Therefore businesses must adopt new approaches to device configuration and control.  This will include a new layer of network software which will instantiate, orchestrate, and dismantle virtual networks.

But what does this really mean?  Read More »

Hardware vs. software: user questions (part 2)

June 29, 2012 at 5:00 am PST

In my prior blog entry, I answered the first of Durga C.’s questions to me.  Here’s all three of his questions:

  1. What is the role of the hardware in an RDMA transaction?  In other words, why does one need special hardware (e.g., InfiniBand, iWARP, RoCE, etc.) hardware to do RDMA as opposed to a “normal” Ethernet NIC? (see prior blog entry)
  2. Further, can you explain why pure software solutions (e.g., Open-MX) are better than nothing when you don’t have hardware support?
  3. Also, what is the difference between “RDMA” and “RMA”?

Let’s explore the last two of those questions. Read More »

Hardware vs. software: user questions

June 26, 2012 at 1:20 pm PST

Durga C., long-time listener, first-time caller, sent me a few interesting questions that I thought I’d share with everyone.  Here’s his first question:

  1. What is the role of the hardware in an RDMA transaction?  In other words, why does one need special hardware (e.g., InfiniBand, iWARP, RoCE, etc.) hardware to do RDMA as opposed to a “normal” Ethernet NIC?

This one question is surprisingly complex.  Let’s dive in…

Empowering Choice in Collaboration

In my recent blog, Experience Matters in Collaboration (So does Architecture), I shared my thoughts on how we are facing a workplace that is no longer a physical place, but a blend of virtual and physical environments; where employees are bringing their preferences to work and BYOD (“Bring Your Own Device” to work) is the new norm; where collaboration has to happen beyond a walled garden; and any-to-any connectivity is a requirement, not a “nice to have.”

Cisco is committed to delivering a new collaborative workspace that meets our customer’s needs and empowers users to work their way—anytime, anywhere and on any device.  As we announced last week, findings from the Cisco IBSG Horizons Study on virtualization and BYOD  shows that 95% of organizations surveyed allow employee-owned devices in some way, shape or form in the office, and, 36% of surveyed enterprises provide full support for employee-owned devices.   These stats underscore a major shift in the way people are working, in the office, at home and on-the-go, a shift that will continue to gain momentum.

Over the last year, Cisco has demonstrated a commitment to delivering innovative software like Cisco Jabber and Cisco WebEx across a wide spectrum of operating systems, tablets and Smart Phones. We’re seeing tremendous interest in these software offerings. Customers see the value in how these offerings enable employees to work on their terms in the Post-PC era, while still having access to collaboration experiences.

Based on these market transitions, Cisco will no longer invest in the Cisco Cius tablet form factor, and no further enhancements will be made to the current Cius endpoint beyond what’s available today. However, as we evaluate the market further, we will continue to offer Cius in a limited fashion to customers with specific needs or use cases.

Moving forward, we intend to double down on software offerings, like Jabber and WebEx, that provide the anytime, anywhere, and any device experiences. We will leverage key learnings and key collaboration experiences native to Cius in our other collaboration products.

Experience matters, and Cisco is focused on empowering individual collaboration styles more effectively and securely, while providing the broadest choice of collaboration options based on preference, location, and device.

How Smartphone Apps Deliver an Economic Boost

By Howard Baldwin, Contributing Columnist

The place: San Francisco. The time: a Saturday afternoon.

The scenario: after lunch, two out-of-town couples find themselves in a neighborhood where taxi cabs are scarce. One of the women remembers a new iPhone app called Uber that allows you to wirelessly order a Lincoln Towncar and bill the trip to a credit card.

Elapsed time between signing up with Uber and the car arriving: 10 minutes. Estimated incremental cost above a traditional cab: $7.
