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 »

Mobile Location Based Services Trends of 2013

The holiday season which began with Cyber Monday on December 2nd 2013 has just ended and analyzing the impact on mobile commerce sales and location based services unveils some very interesting trends.

Firstly, at the macro level:

  • Online shopping increased in the USA in 2013 by over 16% compared to 2012.
  • From a mobility perspective, almost a third of all online sales (29%) were made from Smartphones or Tablets.

Clearly there are changes in the online marketplace, but in order to examine this a little further, let’s look at a few key questions to help understand what is happening in this marketplace:

  1. What are the major trends?
  2. Is mobile commerce just a US phenomenon?
  3. What impact does location based services have?
  4. Where are the main benefits coming from analytics?
  5. How is privacy fitting in to all this and how is the attitude of mobile consumers evolving?

Extending Zeroconf Services: Cache Tuning

Introduction

With the introduction of Cisco mDNS Service Discovery Gateway in IOS, customers that have implemented the solution are observing client behavior they haven’t seen prior to extending services across subnet boundaries. One of the effects is the duplicate name issue seen when devices with enabled services are moved from one L3 subnet to another L3 subnet and these two subnets happen to be connected to the same router/switch running the Service Discovery Gateway (SDG).

Background

When devices (like a Mac OS X computer) offer a service such as Remote Login (SSH) or Screen Sharing (VNC), they will announce these services using mDNS/Bonjour/Zeroconf using their hostname as configured in ‘System Preferences -> Sharing -> Computer Name’ (see Fig. 1).
