Last fall, I blogged about No SSID Outage or Access Point Stateful Switchover introduced with the AireOS 7.3 release whereby if your wireless LAN Controller fails due to some hardware failure, thousands of Access Points fail over sub-second to the standby controller! This is possible due to continuous synchronization of CAPWAP states, Configuration Changes, Radio Channel and Power, Roaming Keys and Access Point licenses between the two Controllers. This means even if the administrator changes the configuration, channel plans or the clients roam and the primary controller fails; the Access Points will simply fail over in a stateful fashion to the secondary. In this blog, I will share details on the upcoming enhancements to High Availabilty with the 7.5 release.
In the upcoming AireOS 7.5 release, we take High Availability to the next level with two critical enhancements.
1. Today, after Access Points fail over from the primary to the standby controller, each client tries to re-authenticate and the standby controller then checks against its CCKM database whether the client has already authenticated. At the rate of several tens of authentications per second, it can take anywhere from zero to a few hundred seconds for the tens of thousands of clients that are connected to a controller to re-authenticate. The client stateful essentially eliminates this downtime with sub-second failover. Thus the total downtime that any user running a voice-call or Citrix session experiences is 2-3 seconds that the application requires to reconnect.

Last month I wrote about the Connected Mobile Experiences deployment in Nice. One of the most interesting things I saw at the iCity launch in Nice was a real cool application that can leverage the power of Cisco’s Connected Mobile Experiences (CMX) solution to deliver very unique and exciting capabilities.
Imagine visiting a city and being able to leave your friends digital messages that only they can read when they get to a specific location. Or walking into a new area and getting localized information right then about a specific event. Or customizing signage in whatever language in native to the visitor. Imagine being able to create your own sticky note and making it public or private anytime anyplace electronically.
All of these things are just some of the possibilities that are now made available using ‘digital graffiti’ from a small startup in the South of France called Geekgaps.

Earlier this year, I was having a business dinner with an important client in London when I received an IM on my iPhone. The message was from a Cisco colleague, and it said, “I need you to approve a purchase order. Right now.”
So I stepped away from the table, launched an app on my iPhone, read the purchase order, and clicked “approve.” Then I returned to my seat and went back to our dinner without missing a beat. The whole process took maybe two minutes.
Just a few years ago, this transaction would have required a laptop tethered to the network in a hotel or office, and it would have completely disrupted the dinner. This pace of change, leveraging mobility solutions, across IT is unprecedented.
Why are so many businesses turning to mobile enterprise apps? According to Gartner, more than 25 percent of enterprises will have an app store by 2017. Mobile apps are making the promise of BYOD a reality. People love their apps and the highly personalized experience they deliver. By bringing their own devices to work, people can enjoy their work more, use the devices they choose, and do their jobs better and faster—from anywhere. According to Cisco’s latest study, the Financial Impact of BYOD, they can also be more innovative and productive. At Cisco we firmly believe that work is a thing you do, not a place you go.

Remember the time when we were trying to figure out exactly what the Internet was? Web pages and dot coms didn’t make complete sense. Wow, how times have changed. Today, our world revolves around the Internet. Most of us connect every day. And now, we are doing more than just connecting.
Our team recently joined other industry experts at HITEC 2013, the world’s largest hospitality technology show. Hot topics discussed at the show included the next generation guest, including BYOC (bring your own content), social media, Wi-Fi services, data security, mobility and more. But one topic stood out among the others – the next big innovation cycle for hoteliers.
So what is the next big innovation cycle for hoteliers?
The one thing about innovation in hotels that stands out to me right now is that it’s almost a constant two-way dialogue between the hotel and guest. When we leverage the network beyond just connecting to the Internet, the possibilities are nearly endless. This two-way dialogue creates an opportunity to better serve customer needs. And if we pay attention to guests’ dialogue and understand their daily physical and digital habits and desires, there is no more assuming what those needs are. By constantly gathering data to determine future needs, we can create a system that not only is a solution, but can help determine solutions for the future. Read More »

Editor’s Note: This is a guest post by two Wireless Networking Group interns, Nonie Grewal and Nivedita Jagdale, to capture their thoughts on the Connected Mobile Experiences Hackathon that they helped plan and execute.
June 29th marked the start of the Connected Mobile Experiences (CMX) Hackathon in the Cisco San Jose campus. CMX, powered by the Mobility Services Engine, provides a unique way of providing personalized real time location services over Wi-Fi. CMX aims to increase customer-oriented and operational efficiencies through analytics and personalized mobile services. The contestants at the hackathon were invited to help build prototypes that could help complement these goals, focusing on enhancing user connectivity and visibility.
As summer college interns volunteering at the event, we walked into the Deep Space Nine room where the hackathon was held, to find clusters of intense developers at each table. With each passing minute, we felt the name “Deep Space” seemed apt for the cause it was hosting – deep thought and real coding! Read More »
