As Wi-Fi continues to be the primary mode of access, enterprise Unified Communication(UC) applications usage is increasing with smartphones, tablets and laptops.
Customers are asking, is there anything I can do to prioritize Jabber or Lync traffic over others or even identify how much of the traffic is really collaboration traffic vs. other types of media. The recently introduced Wireless Release 7.6 enhances the ability to classify Microsoft Lync 2013 and Jabber with Cisco WLAN Infrastructure.
In the first blog about Application Visibility and Control over Cisco WLAN, I captured what is AVC and the capabilities included in the release 7.4. In a subsequent blog, I had captured a success story about a customer who benefited from the reliability by deprioritizing scavenger level applications as well as captured highlights of the enhancements in release 7.5. This blog captures how the release 7.6 allows popular collaboration applications to be accurately classified and prioritized as well as provides a teaser to some of the innovations that can be expected in the future.
What exact capabilities AireOS 7.6 provide ?
The protocol pack 6.3 introduced in AireOS 7.6 allows you to identify and prioritize not just Jabber but also sub-classify Cisco Jabber Audio, Cisco Jabber IM and Cisco Jabber Video. Customers may want to prioritize the Cisco Jabber Audio as the highest priority while the others may be lower priority. Similarly you can classify not just Microsoft Lync but also Microsoft Lync Audio, rtcp and Microsoft Lync Video and thereby prioritize them separately. Read More »

We are all witnessing the continued proliferation of mobile devices on our networks. This device explosion has led to an increase in wireless service discovery and announcements protocols like Bonjour, DLNA (Digital Living Network Alliance), and UPnP (Universal Plug and Play). For example, Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. Bonjour is built-in with Apple’s operating system including iOS and available on Windows as a common plugin while DLNA and UPnP are built in with Android and Windows operating system respectively.
The usage of these protocols comes with a big price: an increase in Multicast traffic because they are all inherently sent as a broadcast transmissions in Wi-Fi networks.
But why is an increase in Multicast traffic bad for users?
The answer is simple: multicast traffic increases mobile device battery consumption by forcing the device host processor to wake-up more often than required.
Have you ever wondered a drop in battery percentage while your mobile device is sitting idle of hours in your pocket? If yes, then you are probably on a network with a high percentage of multicast traffic emanating from every mobile device that is part of it.
So how can we save battery drop taxes on our mobile device without losing the ability to support these protocols? Read More »

As a mobile expert and thought leader, I’m frequently asked about what the next big thing in mobility will be, and my answer often surprises inquirers – mobile’s future is a disappearing act.
When most people think about the future of mobility, they think of larger, possibly flexible mobile screens, thinner and lighter designs, and the incorporation of new, currently unavailable technologies, but the reality isn’t so black-and-white.
In past posts, I’ve explained why mobile devices gained ubiquity – in sum, they’re submissive to us (they’re easy for us to handle and manipulate), and the future of mobility is no exception. Think about it – what could be easier to handle than nothing at all? In time, we’ll begin to see technologies that virtually disappear until we need them, at which point we’ll see them front-and-center, or discretely in our periphery, depending on the optimal viewing location and utility offered. In the interim, mobile devices (both their hardware and software) will hybridize in an effort to complete the transition to virtual disappearance. Read More »

In their highly anticipated announcement this week, Apple introduced two new phones, the iPhone 5C and iPhone 5S, and confirmed that iOS 7 would be released on September 18th. Techies like myself took note that iOS 7 will include quite a number of new features. We at Cisco want to help you understand what iOS 7 means for your network, so here’s a quick blog to sum it up:
How does iOS 7 impact your wireless networks?
Soon your employees and guests will be upgrading to IOS 7. Did you know up to 20% of traffic to mobile devices is software upgrades, application updates and synchronizing your devices via the cloud? Cisco’s Application Visibility and Control technology can help you identify and tame these applications and is available on the routers, Wireless LAN and visible via Prime Infrastructure. In addition, Cisco’s ISR can cache these updates to reserve valuable and expensive WAN bandwidth. More details about protecting the WAN is available in another blog.
If you leverage a Captive Portal, you will experience a change in behavior. Apple has enhanced the Captive Network Assistant (CNA) functionality iOS 7 making it more robust. Cisco has proactively developed and tested a new version of wireless LAN controller code to interoperate with Apple’s new implementation while ensuring a seamless experience for all other clients.
Finally iOS 7 also has significant security and manageability enhancements to improve productivity for the enterprise.
What do you need to do in order to optimize for iOS 7? Read More »

At WWDC this week, Apple announced that their new Macbook and Macbook Air are 802.11ac enabled. As we predicted in our red-hot Client Adoption blog earlier this year, the list of 802.11ac clients, like the new Macbooks and Samsung Galaxy S4, will continue to grow and expand throughout 2013. These devices come with the promise of Gigabit wireless, at faster speeds and better performance. How will your enterprise networks meet those expectations? The Cisco Aironet 3600 with 802.11ac module is your ticket for enterprise-class 802.11ac wireless.
Cisco Aironet 3600 AP with 802.11ac module
The 802.11ac module will make these new clients fly at new higher speeds–3 to 4 times faster than 802.11n. So if you are connecting your new Apple device to an Enterprise Network supporting Cisco’s 3600 AP with the 802.11ac module, you will be able to get some of the highest bandwidth rates ever seen out of your Wi-Fi network which will open the opportunity for better quality video streams, better online collaboration and the support of more high-bandwidth demanding applications. Check out the Aironet 3600 here: http://www.cisco.com/en/US/products/ps13128/index.html
Can’t get enough of 802.11ac? Neither can we. Read More »
