Though an argument can be made that a shift to symmetric internet access will lead to applications being created to take advantage of bandwidth symmetry, present traffic trends do not favor heavy internet service provider investments in symmetrical bandwidth for consumer connections.
With the caveat that a big shift to peer-to-peer distribution of consumer entertainment would have a big effect, growing internet distribution of content has intensified the asymmetric pattern of internet access traffic. That matters since video dominates core, metro and access network traffic load.
Globally, IP video traffic will be 82 percent of all IP traffic (both business and consumer) by 2022, up from 75 percent in 2017.
Upstream traffic has been slightly declining as a percentage of total for several years, Cisco says. It appears likely that residential Internet traffic will remain asymmetric for the next few years, at the very least.
Global IP video traffic will grow four-fold from 2017 to 2022, a CAGR of 29 percent. Internet video traffic will grow fourfold from 2017 to 2022, a CAGR of 33 percent.
The sum of all forms of IP video, which includes Internet video, IP VoD, video files exchanged through file sharing, video-streamed gaming, and video conferencing, will continue to be in the range of 80 to 90 percent of total IP traffic, Cisco says. Globally, IP video traffic will account for 82 percent of traffic by 2022.
User-generated content and security camera video have not affected the asymmetric traffic pattern, downstream and upstream.
