The ISR 4000 Series - One Platform to Rule Them All

This week Cisco announced an entirely new approach to delivering rich services to the Enterprise branch office with the introduction of the ISR 4000 Series. For those folks paying attention over the last year this really was no shock. In fact the ISR 4451 announced at Cisco Live 2013 is the first member of this new series teasing the concepts and technologies represented today in an entire portfolio of platforms.

The ISR 4000 Series consists of 5 platforms that spread the architecture and technology introduced with the 4451 across a portfolio designed to meet the needs of most branch offices. With performance-on-demand, these 5 platforms hit 10 different performance levels, from 50Mbps to 2Gbps with services, giving IT departments the capability to pay for only the capacity they need with the option to increase performance with a simple license. The multi-core control/data/services plane CPUs with included virtualization through Service Containers, server replacement capabilities with the UCS E-Series and flat performance-curve with services are truly revolutionary in the industry, so how did we get here?

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.

Apple iOS 8 and MAC Randomization: What It means for Cisco’s Connected Mobile Experiences (CMX) Solution

As you may have read, Apple's iOS 8 will come with some changes to the way MAC addresses are exposed in Wi-Fi probe requests. Apple’s intent was to provide an additional layer of privacy for consumers and target those companies that offer analytics without providing any value to the end consumer. We’ve been getting some questions about what this means and how it impacts our Connected Mobile Experiences (CMX)  solution, so we wanted to clear this up for our customers.

What does this mean for you? 

First and foremost, Cisco has always been dedicated to privacy for our customers and their end-users. There are four aspects of privacy that are built into our CMX solution:

1. Anonymous Aggregate Information: All analytics are based on aggregate, anonymized location data.

2. Permission-based: Users have to opt-in to join a Wi-Fi network or download an app

3. MAC Address Hash: Users’ MAC addresses can be hashed before exposing to 3rd party apps

4. Opt Out: End-users are always presented with the option to opt out of location-based services

The true value of CMX analytics for organizations is in aggregate location data to be used for business analysis to improve the customer experience for end-users. Providing customers with high performing Wi-Fi not only keeps always-on mobile users happy and opens the doors to delighting customers with more personalized experiences, but also helps provide more granularity to those aggregate trends to feed back into the experience creation machine. Win-win.

What does this mean for our CMX value proposition? Read More »

Non-stop Wireless at Johns Hopkins Hospital

June 30, 2014 at 10:42 am PST

Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.

Patients are the focus at Johns Hopkins Hospital. Johns Hopkins uses state-of-the-art technology in their hospitals to ensure that patients get the latest advances from surgical tools, radiologic imaging suites with the best diagnostic capabilities to something as humane as sound-absorbing private rooms for each patient.
