Non-Stop Wireless Network at John Muir Health

April 15, 2014 at 8:12 am PST

Previously I have blogged about No SSID Outage and No Client Reauthentication whereby even if your Cisco Wireless Controllers were to fail due to any reason, the clients will NOT experience any downtime due to Stateful Failover functionality to a Standby Controller. What could be better than that? Controllers that never go down!

A picture is worth a thousand words! As you can see the above the WEBGUI on a 5508 series wireless controller shows that, it is running 7.0 code which was an MD release, has been operational for over a thousand days or over three years! Read More »

Cisco Technologies featured at OFC/NFOEC’14: Programmable, Converged & Highly Scalable

By Leonard Luna, Senior Marketing Manager, Cisco Service Provider Solutions

This past March at OFC/NFOEC’14 in San Francisco, California, Cisco was a once again a significant part of the leading edge dialog.  Organizers took full advantage of the dynamic Moscone Center facilities to create a highly compelling environment for suppliers, analysts, industry experts and end users to collaborate on optical and networking solutions.  The event was very successful for Cisco from both a face-to-face and social media perspective.


Above: View onsite observations from Sanjeev Mervana, Cisco Sr. Director Product & Solution Marketing, direct from Cisco booth at OFC’14

This year, we leveraged one of our largest booths ever to create some ambitious live demos showcasing how Evolved Programmable Networks (EPN) are designed to handle the challenges and opportunities presented by the Internet of Everything.  The entire Network Convergence System (NCS 6000, 4000 and 2000) was live within the booth, and one year after its introduction at OFC, an expanded Cisco CPAK family of transceiver modules was also featured, including the LR4, SR10, ER4 and show favorite – the Cisco CPAK 10 x 10G LR solution.

If you missed your opportunity to engage with Cisco at OFC’14, you can view the following video demos created right on the show floor to see a few of our attendee’s favorites:  Read More »

Increasing Demand for Higher Location Data Resolution

Cisco has been playing a critical part for retail, healthcare, hospitality and transportation organizations to gain an understanding of how end-users move throughout an organization’s physical location. This is done through our Cisco Connected Mobile Experiences (CMX) solution.

With all the valuable information CMX provides, the demand for even more accurate data has been growing. Location accuracy has been a hot developing field and, as I mentioned in announcing our Best of Interop Finalist status in the wireless category last week, Cisco’s taken the lead in redefining how this location-based data is acquired.

In the past many solutions have relied on the probing performed by the mobile device to acquire location-based data.  In recent months this approach has shown diminishing returns. The underlying issue is that this data is reliant on how frequently the mobile device probes an access point. A couple issues that arise include:

-       Mobile device manufacturers are reducing the frequency of device probing to conserve battery. This reduces the number of data points collected and impacts the accuracy of the data

-       Different manufacturers probe the access point with varying frequency so some devices deliver more accurate information than others skewing the location analytics data.

At Cisco’s annual Partner Summit event we are revealing some key areas of focus for the upcoming Cisco v8.0 release. Although the list is not inclusive of all new functionality, I would like to highlight some steps we are taking to bring CMX to meet the ever-evolving demand for location-based data.

CMX Analytics: An Inside Scoop on CiscoLive! Milan #CLEUR

cmxclmilan1

Today is the final day of a very busy and successful Cisco Live Milan 2014. Read my initial observations from the event earlier this week.

As the event draws to a close, lets look at some of the location analytics available via Cisco’s Connected Mobile Experiences solution (CMX) and perhaps try to answer some of the following questions about the event.

For this I will just focus on the World of Solutions Show floor -- approximately 800,000 sq feet in size, and containing all the Cisco Booths and the partner displays.

  1. How many people actually visited the world of solutions?
  2. How many people did  the different Cisco Booths attract?
  3. Where was the busiest part of the show floor?

These and other insights can be derived from looking at the business intelligence that emerges from CMX. Read More »

HDX Blog Series #4: Optimized Roaming

Editor’s Note: This is the last 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 1 here. Read part 2 here. Read part 3 here.

If you’ve been a long time user of Wi-Fi, at some point you have either observed someone encounter (or have personally suffered from) so called “sticky client syndrome”. In this circumstance, a client device tenaciously, doggedly, persistently, and stubbornly stays connected to an AP that it connected to earlier even though the client has physically moved closer to another AP.

Surprisingly, the reason for this is not entirely…errr…ummm…unreasonable. After all, if you are at home, you don’t want to be accidentally connecting to your neighbor’s AP just because the Wi-Fi device you’re using happens to be closer to your neighbor’s AP than to your own.

However, this behavior is completely unacceptable in an enterprise or public Wi-Fi environment where multiple APs are used in support of a wireless LAN and where portability, nomadicity, or mobility is the norm. In this case, the client should typically be regularly attempting to seek the best possible Wi-Fi connection.

Some may argue that regularly scanning for a better Wi-Fi connection unnecessarily consumes battery life for the client device and will interrupt ongoing connectivity. Therefore the “cure is worse than the disease”. But this is true only if the client is very aggressively scanning and actually creates the complete opposite of being “sticky”.

The fundamental issue with “stickiness” is that many client devices simply wait too long to initiate scanning and therefore seeking a better connection. These devices simply insist on maintaining an existing Wi-Fi connection even though that connection may be virtually unusable for anything but the most basic functionality. Read More »
