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 »

Virtual desktops, virtual workspaces, voice, video, ... virtual reality

Today, there is lots of buzz around the big news from Cisco and our ecosystem partners with the launch of next generation VXI validated solutions.   If you missed our launch event, you can still get all the details online via our community.

Cisco Virtualization Experience Infrastructure (VXI) delivers desktop virtualization with secure access to data, voice, and video for fixed and mobile devices.    

Pretty cool but, why is virtualization important for government agencies? 

  1. cost control, more than ever government agencies are focused on strategies to improve operational efficiency and reduce costs
  2. flexibilty, allow government workers ability to work in different workplaces, from city hall to public works, with choices of different combinations of virtual desktops, voice, and video devices including latest smartphones, tablets, and Cisco Virtualization Experience Clients (VXC)
  3. security, better security and control of information in the data center rather than distributed endpoints and with the "bring your own device" (BYOD) to work phenomenon, security is more critical than ever
  4. uncompromised, helping government agencies achieve mission objectives without compromising cost or resilience mandates
