Staying Connected at Northern Kentucky University

July 3, 2014 at 9:07 am PST

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

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 »

Part 2 – Virtualized Services in an EPN World?

In part one of this series Gina covered the basic definition of an Evolved Programmable Network or EPN and its linkage to the Cisco Evolved Services Platform (ESP).   Figure 1 offers a quick visual recap.

The Network After 25 Years of Cisco Live!

#clus1A 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.

Cisco Evolved Programmable Network: The Beginning of a New Era in SP Networking

June 3, 2014 at 2:26 pm PST

ginaWritten By Gina Nienaber, Marketing Manager, SP Product and Solutions Marketing

This is the first blog out of a series of three covering  “What is the Evolved Programmable Network (EPN) Era and Why Evolved Programmable Network (EPN) Now?”

Those of us who have been around in the industry for a few decades will remember the first arrival of the “big bad wolf” that tried to blow down the service provider’s house. This wolf presented itself in the form of the commoditization of IP services and high traffic growth rates that limited service provider profitability options forcing them to move away from dedicated TDM-based networks that supported a single video, voice, data, or mobile service. Service Providers partnered with Cisco (and others) to build more scalable and lower costs converged IP Next Generation Networks (IP NGNs) and entered the IP NGN era. In doing so, a new wave of innovation and service revenues followed.

Until of course, “the big bad wolf” arrived on the scene again, also known as “exponential traffic growth, especially in mobile video, and this time he brought his friend along for the ride -- the Internet of Everything (IoE).  Cisco VNI predicts IP Traffic alone will grow 300 percent to 1.4 zettabytes annually by 2017. Most of you are already experiencing the pains of exponential traffic growth and some of you believe, as we do, the next wave of dramatic Internet growth will come through the confluence of people, process, data, and things — or the IoE! And IoE predictions are off the charts as well.  Cisco estimates that 99.4 percent of physical objects in the world are still unconnected. With only about 10 billion of the 1.5 trillion things currently connected globally, there is vast potential to connect the unconnected via the IoE.

When you combine exponential traffic growth with IoE impact on the horizon what do service providers get?  You guessed it -- cost and network complexity are rising at a faster rate than revenue. In order to deal with these challenges, (I would rather call them opportunities), network transformation is not optional, but essential for the next wave of growth and propriety.

This might also be a good time to mention the major innovations in cloud and virtualization technologies such as SDN and NFV are allowing for new agile competitors to enter into the market and are challenging traditional providers for their revenue streams by changing the service delivery game and giving the customer control over their service instantiation with consumption based business models.  If you would like to review a quick snapshot of the challenges providers are facing today see the Cisco EPN At-A-Glance.

Are you convinced we need to move from the IP NGN Era to the EPN Era Yet?  If not keep reading -- you will be.

RetailMeNot Leverages Cisco and Plixer for WLAN Optimization

April 1, 2014 at 9:23 am PST

Founded in 2007, is the largest digital coupon site in the US.  They help hundreds of thousands of customers save money when shopping online. They are headquartered in Austin Texas, in the hip “Live Music Capital of the World”.  Since the company went public in 2013, the company has doubled the number of employees from 250 to over 500.

In previous blogs, I have covered what is AVC, SuccessEHS and how Plixer’s Scrutinizer accepts Netflow, sFlow and IPFIX exports. This post will cover how these key products are combined by RetailMeNot in their WLAN deployments to optimize and support this fast growing company.

Recently Michael Patterson, the Founder and Product Manager at Plixer, Matthew St. Jean the Marketing Manager at Plixer and I had an opportunity to talk to Tim Tyndall, the Lead Network Engineer at RetailMeNot.  Tim shared with us the highlights of the wireless LAN deployment and explained how they use Cisco Application Visibility and Control and Plixer’s Scrutinizer to stay in control of how their WLAN is being utilized.

Tim described the environment and culture that has become a huge part of the company’s success.  RetailMeNot  provides hip new offices for its employees with open work spaces and other awesome perks.

The Cisco powered wireless network supports this initiative. In fact, nearly all network connectivity is wireless. He said that employees are issued a laptop by the company and many carry in their own smartphones and tablets as well; Most of those devices being from Apple.


Employees can roam freely with reliable service that spans the company’s five floors. Even during large meetings where access density increases dramatically, service continues without any interruptions and the performance metrics they can obtain using NetFlow is exceptional and reinforce that the traffic is optimized.
