Virtualization: Can We Deconstruct the Problem and Opportunity?

This was the title of a November 19 2013 panel that I had moderated in Washington D.C. at the MPLS-SDN Isocore Conference.

The abstract for this conference was designed to be a bit provocative, specifically:

“ Virtualization as a concept is not new. However, in the context of Software Defined Networking,the virtualization discussion has been focusing on overlay functions e.g networking. What about virtualization overlays and interworking with existing architectures?   What are the implications to performance and management?   Are we speaking the same language?

The panelists will have an opportunity to articulate the virtualization problem space for the industry and the opportunity for the industry to address.”

My panelists included the following individuals: Read More »

Capitalizing on Today’s Market Disruption with Professional Services

This is the first of a series of blogs that I plan to publish to start a dialog with our partner community. In these blogs, I’ll discuss the huge industry disruption now taking place, how Cisco Services is transforming itself to respond to that disruption, and how current and prospective partners can profit from the lucrative opportunities this disruption is creating.

In our industry, we see major disruptions every 20-25 years. Inflection points occur, platforms shift, and customer needs change dramatically. Today, we find ourselves well into the next major market evolution, one of unprecedented scale. To learn more, click here to view an online seminar where I discuss these trends with Chris Barnard, IDC AVP EMEA Network Life Cycle Services, and Leslie Rosenberg, IDC Research Manager, Worldwide Network Life Cycle Services.

Together, we are addressing the challenges — and tremendous opportunities – related to cloud, virtualization, big data, programmable networks, new consumption models, and changing buying centers. Some of our existing partners are executing on these opportunities and evolving their practices to compete, win, and ultimately enable innovative business solutions for all our customers. At the same time, we are attracting new partners into our ecosystem: ISVs, industry vertical players, and consulting firms, to name a few. Read More »

This October, Barcelona will begin the journey towards joining the ranks of Nice as a connected city, making it the perfect hotbed for displaying the Connected Mobile Experiences (CMX) solution in action. During the IoT World Forum, Cisco will showcase the CMX solution in a number of venues, both indoors and out.

CMX Analytics will be displayed on a large screen in the lobby of the iconic Hotel Arts on Barcelona’s waterfront, where the conference is being held. We will display dwell time, patterns of movement, crowding, etc. each day for the conference itself, showing real insights on the venue and attendees. Read More »

Interference Detection and Mitigation with Cisco CleanAir

The previous blog on CleanAir went in depth on how MSE uses CleanAir information to locate interferers and the impact zone for each interferer. This blog takes a step back and gives an overview of the CleanAir technology.

How Interference Affects Your WiFi

802.11 devices operate in the 2.4GHz and 5GHz unlicensed bands. These are unregulated and experimental bands. As such, there are way more non-802.11 devices, including but not limited to cordless phones, video cameras, microwave ovens, Bluetooth headsets, DECT phones and even X-Boxes. Now even more devices are coming out that emit in these bands. These devices interfere with your WiFi network since they don’t work cooperatively with 802.11 devices, causing reduced network capacity and coverage, poor quality of voice and video, and link failures.

When an 802.11 device is ready to transmit and it senses interference, it will hold off transmission until it is finished.  If it is in the middle of a transmission where it has sent a packet and never receives an acknowledgement, then it will try to send the packet again. Issues like these  impact the throughput and capacity of your Wireless Network. An interferer like a microwave oven, which emits interference on a 50% Duty Cycle, will reduce the throughput by 50 percent. In the case of an interferer like a video camera, which emits interference at 100% Duty Cycle, when seen at Access Point above CCA threshold will stop the Access Point from beaconing. Due to this clients will not attempt to associate. Read More »
