Editor’s Note: This is the second of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit www.cisco.com/go/80211ac. Read part 1here.
With any new technology comes a new set of obstacles to overcome. 802.11ac is no exception. Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.
What’s Different with 802.11ac?
802.11ac means higher data rates, which means more packets per second (PPS). There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation. Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!
With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS. More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board. Read More »
Educators face a number of challenges, from increased pressure to improve student performance on standardized tests to shrinking state and local budgets. In addition, instructors are leaving their classrooms for better opportunities, and students’ learning skills are tuned more to social media and new technologies than to traditional educational models. These challenges require that institutions transform the way they retain talent—and the way they reach and teach students.
Although they have used recorded videos for many years to introduce new experiences to students, and some have started employing web-based video technologies to save travel costs, most educational institutions do not understand the critical role video can play in scaling resources to improve education quality despite budget constraints.

The announcements include the most scalable 10 Gigabit Ethernet Layer 2/Layer 3 Fabric in the industry. The claim is that no matter how diverse your data center demands may be, Cisco offers unparalleled abilities to arm you with efficiency, agility, innovation and differentiation. So no matter your form factor, physical, virtual or cloud- based environments are all positively impacted with an industry leading fabric-based approach.
Filled with geeky goodness….look at what you will find!

On October 25 at 9:00 am PST/ 12:00 pm EST , join a very special webcast “Evolutionary Fabric. Revolutionary Scale “ with customers, analysts and Cisco executives and experts for conversations about the benefits of Cisco Unified Fabric .
“There is a lot going on in the data center these days – There is a continue expansion of virtualization , we see broader adoption of cloud and we see emerging trends, big data being the newest and trendiest of the hot data center topics – So there are folks out there who will tell you, you know what each of these needs special equipment, they have unique requirements , your regular infrastructure will not be able to handle these requirements So what we do believe is that each of these requirements, big data, cloud have their own specific needs , we truly don’t believe that you need purpose built hardware , at least if your infrastructure is built the right way “ Omar Sultan
So this webcast is really about learning how Cisco’s fabric-based approach delivers architectural flexibility across physical, virtual and cloud environments for any application.
For Brian Gracely the equation is simple to remember : Cisco Unified FABRIC is Fast, Agile, Best of breed, Resiliant, Innovative, Cisco-based
This is another post that’s suited for your coffee or tea break so grab a bag of biscotti!
A few months ago, I started a series on the evolution of social media adoption within an organization. Phase 1 talked about the Missing (which I introduced earlier as the Mistrusting), phase 2 discussed experimentation, and in phase 3, the Integrators learned the importance of looking at social media as part of the bigger picture. The difference between stage 3 and stage 4 practitioners is the level of sophistication, spread within the organization and access to resources.
PHASE 4 PRACTITIONERS
The Integrators know how to bring together the various components to achieve a shorter term marketing goal but phase 4 practitioners know how to use the selected tools across their programs and activities, and connect with their audience on a deeper level. They have a much clearer understanding of their careabouts. Their conversations feel more natural, human and well, more conversational. They understand that content needs to be a combination of industry, everyday and company topics -- and know how to do it. They understand that each channel needs to have its own purpose and its own deliverables -- and know how to do it. They are in it for the long haul and look at social media more strategically and holistically.
There is a fundamental change in their approach: Read More »
