Network analytics business Sandvine always provides useful insights into what services are consuming the most network resources, or as they like to say, which services have the highest ‘traffic share’. Drawn upon data obtained from the networks of 150 tier 1 and tier 2 fixed and mobile operators, they may not have much perspective on traffic in China or India, but otherwise see what is happening across a significant proportion of the internet. The headline findings from their most recent Phenomena Report are that:
- Almost 58 percent of global downstream internet traffic is used for video; 15 percent is Netflix. Although Netflix consumes most total traffic, it is a more efficient streaming service than those of major competitors.
- More than half of all internet traffic is encrypted. The rise in encryption is linked to increased adoption of Transport Layer Security (TLS).
- BitTorrent file sharing piracy is still widespread, with torrents representing 22 percent of global upstream traffic. In Europe and APAC the BitTorrent protocol consumes more upstream bandwidth than any other.
- Major live sporting events now cause noticeable peaks in network demand. They also lead to piracy, with up to 40 percent of all World Cup streams being pirated.
- Video game downloads have grown to become a significant proportion of all traffic. Steam and Playstation downloads are especially prominent in Europe.
- The IoT device which generates most internet connections is the Nest Thermostat. Though IoT traffic remains a small proportion of total traffic it is becoming more noticeable, partly due to the increased popularity of voice assistants like Alexa and Siri.
Understanding the trends in traffic will help networks to plan for them. They are also vital for businesses seeking to manage the risks related to providing their services over the internet.
