Back in the earliest days of television – before satellites began spraying an instant and national video footprint over the Earth – operators wondered whether it made sense to expand spectral capacity any further. At the time (early 1950s), most markets topped out at three channels. The big question was this: why would we ever need room for more than 12 channels of television?
These days, there’s a similar refrain, with a slight shift in tune. It goes like this: why would we ever need a Gigabit-per-second of bandwidth? Read More »

The Cisco Enterprise Mobility group uses this mobility blog as a platform to provide you the most up-to-date information about our products and solutions, showcasing our thought-leadership in the mobility industry and innovative and comprehensive portfolio. So let’s revisit some of those topics we covered over the last year.

Network customers have always bought networks for one and only one reason: to run their applications over them. Yet for most of that time, those networks have been largely oblivious to the composition of the network traffic they carried. Traditional network tools could tell you whether your network was having a lot of errors, or whether a given link or interface was congested, but they couldn’t tell you what was congesting your network, beyond the limited granularity of a few well-known ports. Finding out that you’ve got a lot of HTTP or HTTPS is not very helpful in finding out whether you’re swamped by personal traffic that needs to be controlled, or by legitimate business traffic that requires an increase in effective bandwidth.

With the growing influx of new mobile devices, connected things, bandwidth intensive applications and more data, the network is more relevant to business success than ever before. Back in June of 2012, Cisco saw that we needed to move away from multiple network systems loosely linked together to an agile and simple infrastructure, streamlined policy and centralized management would be needed to support new business demands. We called it Cisco Unified Access and we aligned the solution to three pillars: One Network, One Policy and One Management.
For the last few years, we have focused on delivering new products and functionality under this Unified Access model. Below is a timeline of products released as part of the Unified Access framework. Cisco lead the way in delivering gigabit 802.11ac Wi-Fi., converged wireless control in access switches and through the acquisition of Meraki – a complete cloud-managed network solution.
The timeline above doesn’t represent every feature and function we have delivered, but it shows Cisco’s commitment to this Unified Access model, both from a cloud-managed and on-premise solution perspective.
Today, Cisco is announcing a number of new products and new functionality to existing products that will help mobilize the workforce, secure the business and increase IT agility. The announcement includes the following: Read More »

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 »
