Unless you’ve been living under a rock for the last two weeks, you know that the FIFA World Cup is in full swing. Stakes are higher than ever as we move into the semi-finals with more and more people tuning in to cheer on their favorite futbol teams. In fact, FIFA just released a media release yesterday about how this year’s 2014 FIFA World Cup™ has set new records for streaming data traffic around the world. My colleague Ido blogged about IWAN helping with the bandwidth overload caused by the FIFA World Cup last week, so let’s dive deeper and talk about video and high density.
There is no denying it: your employees and customers are streaming video. While the volume of that streaming dramatically peaks around game times during the World Cup, it should be no surprise that today, mobile applications, largely video, are increasing mobile traffic across networks. That’s straight forward: apps + video = bandwidth drain. Combine that with the fact that people are touting multiple devices--think a laptop and a smartphone, maybe a tablet, too. This means high density--lots of clients and devices on a single network. These circumstances trigger three potential yellow cards to cross an IT person’s mind – let’s see how we can avoid them.
YELLOW CARD #1: Rich Media Optimization
As an end-user, the common expectation is that I should get the same crisp, clear, rich media or video experience across all platforms—I don’t care if it’s my phone, my tablet or my laptop: make it high definition. This is harder said than done.
It is not easy to provide the same rich media experience across wired and wireless devices. Traffic from wireless devices has to travel all the way back to the controller in a data center and then back to an access switch before reaching its destination. It’s called the hairpin effect. The result is that video over Wi-Fi could look grainy. That won’t do for the current generation of high definition junkies. Read More »

Northern Kentucky University is among the fastest growing universities in Kentucky. It hosts over 15,000 students with about 13,000 undergraduate and 2,000 graduate students. The goal of the wireless program at NKU is to provide secure, robust and ubiquitous wireless access throughout the campus, both indoors and outdoors. This ensures that students always stay connected and feel at home. The classrooms are equipped with smart technology to ensure that the teachers can benefit from technology when collaborating with students. The IT team has blanketed the libraries, the classrooms, the dorm-rooms as well as the outdoor areas with Wi-Fi. In the previous blog in 2012, we described how the Cisco 7.5 release allows networks to recover with no client re-authentication in the rare event of your primarily wireless LAN controller goes down.
At a Glance:
Located in: the Highland Heights Kentucky
Number of students: 15,000 of which about 2000 stay in residence halls
Number of teachers/staff: 2000
# WLAN clients: Approximately 8500 concurrent clients
Access-Point Model and Units: 1200 units of AP models including AP702W, 3502, 3602, 3702, 1550 and a few older Access Points which are being phased out
Controller Model and Units: 2 Pairs of WiSM2 operating in 184.108.40.206
Switch Models: Various models 2960, 3650, 3850, 3750X and 6500
Prime Infrastructure: 1.4.2
Mobility Services Engine: 7.6
Deployment Details: We talked to Christopher Johnson, the Senior Infrastructure Systems Analyst II at Northern Kentucky University to capture some of his thoughts around their choice of this solution and the associated benefits. Read More »

Food for thought
The other day, I went to the café to grab my lunch and notice something that got me thinking of an IT problem we’re going to see more and more.
I’m not a soccer sport fan but of course I am aware of the 2014 FIFA World Cup™ event that is happening.
Anyways, I saw a guy watching a live stream of the game between Iran and Nigeria on his mobile device and it got me thinking “I wonder how much bandwidth this thing is taking?”
All major sports event like the Superbowl, World Cup, NBA Finals, PGA tour, Olympics, etc. are streaming LIVE games and many people around the globe are watching the World Cup during business hours as its always 9 to 5 somewhere. Read More »

A lot can change in 25 years. At the first Cisco Live (then known as Networkers conferences) in 1989, 200 geeks gathered for the inaugural event. Fast forward to three weeks ago, when we welcomed a whopping 25,000 attendees into the arms of our namesake, beautiful San Francisco.
We heard there was some interest in how the network performed at the show, so I wanted to share some of the interesting statistics about the network at Cisco Live! I shudder at the thought of the ancient network from 25 years ago. So here we go:
Wi-Fi Client Devices
This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.
# of Unique Clients
# of Sessions
# of Unique Users
# of Unique APs
Avg Users per AP
Max. Concurrent Connected Wi-Fi Devices
There was a peak of 14216 concurrently connected device at SF this year.

Technische Universität Darmstadt, usually known as TU Darmstadt is a research university based in Germany. It was founded in 1877 and over the last 137 years has grown to be among the largest and most prestigious public universities in Germany serving over 25,000 students per year. It is the alma-mater to many world-wide leaders from Nobel prize winners, a CEO of a fortune 500 company, a president of a country and multiple World Robocup champions.
No wonder, they have a reference from Albert Einstein!
In 2009 TU Darmstadt embraced BYOD with the 5508 Series Controller managing the 1140 802.11n Access Points. Recently we talked to Thomas Vogel, the Head of Network Group and Andreas Liebe, the Network Services Manager who have over 15 years of experience managing WLAN environments. In this blog, we will describe some of the details of WLAN deployments using the 3850 Series Switch and the 5760 Series Wireless LAN Controller to address the new requirements in the school environment.
