Despite the rapid expansion of internet traffic, BitTorrent appears to have diminished in its role as a significant contributor to upstream data sources. The latest report on “internet phenomena” from Canadian network intelligence firm Sandvine underscores notable shifts in the landscape of network traffic.
Two decades ago, prior to the advent of the Web 2.0 era, BitTorrent accounted for an estimated 35 percent of total internet traffic. During that time, file sharing and peer-to-peer applications served as the primary catalysts for data traffic, as there were few alternative sources capable of generating comparable volumes of data transmission.
In the present day, the landscape of the internet has undergone significant transformation. Global internet traffic is largely dominated by video streaming platforms and social services like YouTube, Netflix, and TikTok.
Additionally, piracy-related activities have migrated from peer-to-peer (P2P) networks to streaming websites. Although BitTorrent has been supplanted as the primary source of internet downloads, it continues to contribute its share of upstream traffic.
As of 2013, BitTorrent constituted approximately one-third of all internet upload traffic. By two years ago, its share had decreased to 10 percent of upstream traffic. Presently, according to the latest data from Sandvine, the BitTorrent protocol has seen a significant decline in popularity among internet users.
The top 10 sources of upstream data are now predominantly associated with cloud storage, messaging, and video streaming, according to the Canadian company. Video streaming and social media platforms now command more than half of all upstream traffic on both fixed and mobile broadband connections.
BitTorrent maintains a presence in fixed access networks, contributing to four percent of all upstream bandwidth, albeit overshadowed by services like iCloud and YouTube, which generate substantially more traffic.
Despite its diminished usage, Sandvine acknowledges BitTorrent as a “significant factor” in traffic generation, largely due to the smaller user base. While piracy likely remains a key driver, researchers and academic institutions also utilize the protocol for data sharing purposes. Sandvine anticipates a continued decline in BitTorrent traffic as users increasingly gravitate towards cloud and streaming services for their content needs.
