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 »

FCC Decision Opens the Door for Rural Broadband Access

December 13, 2011 at 6:37 am PST

I heard an NPR story the other day about the FCC‘s recent ruling that diverts monthly fees from rural telephone service to rural broadband service. The “Universal Service Fund” or something similar has been around since the early 20th century, charging a small fee on our phone bills to subsidize phone service for rural areas and the poor.

The newly minted "Connect America Fund" now allocates this money for mobile telephone and broadband in rural communities and needy areas. As I’ve discussed in a blog post earlier this year, access to the internet can not only offer rural U.S. citizens access to critical information, but it can provide them health care benefits that could literally save lives.
