Consume? Too much data traffic and Smartphones Tablet?

Blue Coat Systems has monitored the bandwidth used by an employee who uses two iOS devices (iPhone and iPad). They found that, in a period of two weeks, the corporate network impact was greater than 53 GB.

Since 2009, the adoption of the devices BYOD (Bring Your Own Device) has increased 15 times, with 1.02 million devices by end of this year. According to a recent study "Global Mobility Study" conducted by IDG Research Services, 71% of employees said they were pursuing their companies corporate network using their personal smartphones. Within a month, the weight of these devices in the corporate bandwidth can vary between 4 and 200 GB.

The causes of the phenomenon

From 2009 to date has sold more than 1,000 million smartphones and tablet Apple iOS and Google Android. These devices consume a considerable amount of bandwidth that is seen in other network applications. Data traffic on mobile networks and broadband connections at home, as well as software updates and applications requiring WiFi connection, indicate that this activity falls disproportionately on the enterprise network. At the same time, companies do not have the tools to view or control the use of such devices on the network.

Among smartphones activities involving consumption of bandwidth includes:

  • Operating system updates: Users require that devices are connected to a computer or a WiFi network, so you can download the operating systems that can occupy thousands of MB. As a result, a single mobile device can easily overload the bandwidth of the company with a single click, to the detriment of corporate networks and applications.
  • Download an application: a user downloads an average of more than 40 applications, accessing iTunes from Apple or Google Play, where you have access to about 1.2 million applications. Its size can vary from a minimum amount to thousands of MB. Furthermore, their updates are image files, so that the impact on the bandwidth is roughly equivalent to first download the application itself with each new update.
  • Uploading Photos and video cameras built into smartphones are capable of high resolution photos. Anyone can take photos (of 1-3 MB) or movies (25 to 230 MB per minute) and load quickly on platforms such as Flickr or iCloud to share with your colleagues, friends or family. Similarly, photos and videos can be downloaded easily from colleagues, doubling the impact on the network.
  • Download video and multimedia: thanks to video content available for download through iTunes, Amazon and similar sites, users can consume bandwidth business like never before. The HD videos occupy an average of 3 GB or more, and a full season of a television series requires many more GB. In addition, mobile devices provide access to increasingly widespread, streaming videos. On average, a video on YouTube requires 500 Kbps for download, so a single user in a remote office with a T1 connection will consume 33% of bandwidth while the video plays.
  • Backup in the cloud: iCloud offers users 5GB of free storage in the cloud to synchronize content such as photos, email, music, video and applications all connected devices. The incremental backups are performed daily and vary from a few kilobytes to 20 MB, depending on the amount of data to synchronize. If you also sync photos, this data will occupy several GB.

Business solutions

As corporate laptops, mobile devices can be used in work and leisure activities. However, since these are not registered or issued by the company, many IT departments are not clear about the number of devices connected to the network, applications that use or consume much bandwidth. And most importantly, do not have the means to control their impact. In the absence of effective tools for traffic management, IT departments are helpless before the arrival of the BYOD phenomenon.

In order to minimize the impact of this trend on the network, it is necessary that companies have:

  • Visibility: real-time monitoring of all applications and web content on the corporate network, providing visibility of the traffic generated by the BYOD on millions of sites and thousands of multimedia applications.
  • Control: QoS policies enable administrators to limit network traffic and BYOD rise in proportion to the capacity of the network, which allows high-priority business applications consuming bandwidth.
  • Optimization / Acceleration: protocol optimization, caching combined with the operating system, applications or downloading multimedia content on demand, reducing the impact of initiatives by allowing BYOD corporate videos, such as training, communications and access documents.

These are very interesting solutions for all IT administrators.
