Exabyte Zenith

There is a sense of déjà vu when you read about the competing plans of Greg Wyler’s OneWeb and Elon Musk’s SpaceX to build a network of low earth orbit satellites to provide cheap broadband across the globe over the next few years. Memories of past failures from the late 1990s telecom bubble come to mind with these network plans. Names like Iridium, GlobalStar, Teledesic, and SkyBridge. Maybe, this time, the dreamers with access to billions can get it right!

You never know, there may even be a comeback for broadband over power-lines (not likely according to this article)!

I did come across the latest figures from Cisco in their “ The Zettabyte Era – Trends and Analysis” piece, as previously referenced in this post. As a reminder, gigabyte/terabyte/petabyte/exabyte/zettabyte/yottabyte is a kilobyte to the power of 3, 4, 5, 6, 7 and 8 respectively. Cisco continues to predict a tripling of global IP traffic from 2014 to 2019. The graphics below give some colour on the detail behind the predictions.

Split by consumer and business traffic with each further split by traffic type. Unsurprisingly consumer video traffic is dominating the consumer 24% CAGR.

Growth in the US, Asia and Europe is driving the impressive 29% metro CAGR whilst Asia Pacific traffic is the prime driver for long-haul growth.

The split by region shows the status quo will be maintained in terms of traffic breakdown with Central/Eastern Europe and the Middle East /Africa regions projected to have growth rates of 30%+ and 40%+ respectively as opposed to approx 20% in the main markets.

Exabytes are reaching their zenith and by next year global IP traffic is predicted to exceed a zettabyte.

From tera to zetta and beyond to yotta

One of the great lessons of the internet crash was that the exponential growth in internet activity did not mean a similar level of growth in revenues for many of the new business models which were hyped. I can remember an insightful report before the crash which added up all the expected top-line growth projections and concluded that household expenditure on internet services would have to amount to 30% to 40% of household expenditures if projections were to be met!! Although on a personal basis household expenditure on internet access does seem to be growing all the time, it’s not at anything like the growth in our usage. Not yet anyway!

The graphs below shows the growth in global internet traffic from 2001 to 2012 according to Cisco, split by IP, fixed and mobile internet traffic. Although not on the same scale but in a similar vein, the lower graph shows the monthly peering traffic recorded over the Amsterdam Internet Exchange from July 2001 to May 2014

Historical Internet Growth

For reference, gigabyte/terabyte/petabyte/exabyte/zettabyte/yottabyte is a kilobyte to the power of 3, 4, 5, 6, 7 and 8 respectively.

According to the latest projections from Cisco in their report this month “ The Zettabyte Era – Trends and Analysis”, global IP traffic will surpass the zettabyte threshold by the end of 2016 growing by approximately 20% per annum. Global IP traffic has increased fivefold over the past 5 years, and Cisco predicts an increase of threefold over the next 5 years.

Connected Devices Cisco predictions June 2014

The report highlights a number of core trends including the following:
1) Transition to newer devices will alter network demand and usage.
2) M2M growth will drive the internet of everything.
3) Fixed broadband speeds will nearly triple by 2018.
4) Wi-Fi will dominate access technology.
5) Metro traffic will grow nearly twice as fast as long-haul traffic.
6) IP video will accelerate IP traffic growth through 2018.
7) Bottlenecks may result between peak and average demand times.

Bring on the yotta era!
