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
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.
The graph below illustrates the changes in devices used to access the internet behind Cisco’s projections.
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!
