Take 2: Is Your WLAN Ready for Unified Communications and Collaboration?

November 3, 2014 at 11:48 am PST

In the previous blog, we covered details about Cisco AVC enhancements with AireOS 7.6 that allow you to classify various collaboration applications such as Cisco Jabber™, Cisco WebEx®, Microsoft Office 365, Microsoft Lync, and Microsoft Skype. Many customers have deployed voice-over-WLAN in mission-critical environments. The goal in this blog is to walk you through the collaboration specific enhancements implemented since then, that enable customers to get a great experience when supporting Microsoft Lync over Cisco WLAN.

The above picture shows the timeline for various AVC, policy and Lync enhancements. The crucial updates since AireOS 7.6 are:

Wireless technology enables IB school in Hong Kong to offer individualized learning.

Bring Your Own Device (BYOD)

Hong Kong Academy (HKA) is an International Baccalaureate school with students ranging from pre-school to grade 12. They are a relatively small school in terms of total employees and students. Their goal is to offer a personal and individualized form of learning.

HKA identified that the best way to achieve their goals was to encourage the use of technology to create a community amongst teachers and students. They recently constructed a new building and had the opportunity to build a network to meet their current and future requirements.

Cisco Wins Best of Show IPv6 Product!

The North American IPv6 Summit is the largest annual IPv6 event in North America, designed to educate about IPv6 and the current state of IPv6 adoption. We were honored to receive industry recognition of the Cisco’s IPv6 leadership and continued innovation with the Best of Show Award of Product and Service for the Cisco Wireless Controller.

IPv6-Bestofshow-Award

As you read about earlier this summer, Wireless Release 8.0 added a cornucopia of features to our wireless offering, many of which are targeted specifically for upcoming technologies, including IPv6. Let’s look back to see how far we’ve come:

Anticipating the growing demand of the next generation IP and eyeing the arrival of World IPv6 day, Cisco released the first support for IPv6 in its’ Wireless LAN Controller (WLC) software version 7.0 in 2011. There has been a steady progression of feature support ever since. Client mobility appeared in version 7.2 a year later in time to celebrate the launch of IPv6 on the global Internet.Then came the release of 7.4 and it’s support of First Hop Security tools, enabling organization’s to go beyond the lab and deploy IPv6 in a safe, secure manner.

Cloudburst: iOS 8 Generates 50% Increase in Network Traffic

Many network engineers recall the iOS7 update on September 18, 2013 as one of the most historic download days of their network’s history. All the more reason for us in the wireless world who anxiously anticipated the September 17 release of iOS8.

We asked a few of our customers to monitor the effect of the software release on their networks and the results for the first two days are in. Those in the education and healthcare space in particular are filled with early adopters of WiFi technology and devices, and eager to get their hands on the latest updates.

Joe Rogers, Associate Network Director at the University of South Florida shared this picture with us from 1pm September 17th, showing 1 Gbps more traffic than he would normally see at this time of day:

Another customer, Greg Sawyer, Manager of Infrastructure Services, shared this picture of the iOS8 effect on his network at the UNSW Australia.

He noted that his experience handling the release this year felt smoother than last year, despite the new peak internet download of 4.65 Gbps and 21Tb downloaded for the day! Not too surprising when considering that there were 27,000 concurrent connections on the wireless network and approximately 60% of those being Apple devices.

How should organizations be considering and handling these network spikes? I sat down with Cisco technical leaders Matt MacPherson and Chris Spain (@Spain_Chris) to get some insight on the effect of big updates like iOS8 on the wireless network. Here are some of the highlights of what we discussed:

The World We Live In

The truth is, more and more services are being moved to the cloud—a cloud that will push updates to millions & in the future billions of users and devices on our networks. Read More »

Get Your WLAN Ready for Google Android L and Apple iOS 8

July 24, 2014 at 5:00 am PST

This fall your wireless networks will experience many devices upgrading to the new Android 5.0(L-release) and Apple iOS 8 releases (cue: IT managers groan). There have now been many blogs attempting to capture the enhancements expected with these releases. Today I am going to focus on describing how Android L and iOS 8 may affect customers deploying Cisco enterprise grade Wi-Fi networks based upon our research and testing of the Apple seed. Our verdict: Carry on with business as usual.

Here are four features we predict will have the most impact your networks:

1. Chromecast and Google Cast Enhancements (Android L)

Rishi Chandra, the Director of Chromecast Product Management announced that, starting with the Android L release, users have the ability to cast to your neighboring devices such as a TV without having to connect to your Wi-Fi network. In the demo, a phone used the cellular connection to connect to chromecast through the cloud. A variety of techniques are used to authenticate the users in the same room OR use a pin-code as an alternative. Users can Google Cast an ecosystem of applications or even their own applications over any Android or iOS device as well as Cloud based apps on Chrome.

Predicted Impact: Given that this feature works transparently to the Wi-Fi, it is expected that there is no impact on the WLAN in your classrooms or dorm rooms or auditoriums where this will most likely be used.

2. Peer-to-peer AirPlay discovery and playback (iOS 8)

Starting with the iOS 7.1 release, AirPlay devices will discover an AppleTV via the bluetooth network. Users could also secure their AppleTV via a 4 digit pin-code. With the iOS 8 release, Airplay devices can also mirror their content via Airdrop. This feature offers an alternative method for customers to discover and mirroring of Bonjour traffic without accessing the corporate Wi-Fi network.

Predicted Impact: Again this feature operates transparent to the Wi-Fi and therefore customers using this feature should not see any impact on the WLAN. Cisco wireless customers also have the ability to use the Service Discovery Gateway on Cisco IOS based switches, routers or wireless LAN controllers or the Bonjour Services Directory on AireOS controllers.
