Overview

NTT Communications, a subsidiary of Nippon Telegraph and Telephone Corporation, provided a content delivery network (CDN) through its Smart Data Platform, powered by EdgeCast, offering global content delivery for enterprises. The service, launched in 1999, supported various industries with robust network infrastructure until its deprecation in 2025. Following the sale of Edgio’s CDN business, NTT Communications announced the shutdown of its CDN platform, with services ceasing on January 15, 2025. Customers were advised to migrate to Akamai to maintain CDN functionality.
Streamroot was a provider of peer-to-peer video content delivery network (CDN) solutions, specializing in optimizing over-the-top (OTT) video streaming for broadcasters and content providers. Founded in 2013, the company developed Streamroot DNA™, a WebRTC-based technology that leveraged end-user devices to reduce bandwidth costs and improve streaming quality. It served clients like France Télévisions, Canal+, and Dailymotion, handling millions of daily video sessions globally. Streamroot was acquired by Lumen Technologies (formerly CenturyLink) in September 2019 and is no longer an independent entity, with its operations integrated or discontinued.

History & Notes

NTT Communications leveraged its telecom expertise to deliver CDN services, primarily targeting enterprise clients in Asia and globally. The partnership with EdgeCast enabled features like instant purge and real-time logs, but the service’s reliance on Edgio led to its discontinuation after the 2024 asset sale to Akamai. Some customers may still access archived documentation or support through NTT’s sales channels during the transition period.
Streamroot’s technology was notable for its hybrid approach, combining peer-to-peer delivery with traditional CDN infrastructure to reduce buffering and improve quality in bandwidth-constrained regions. Its acquisition by Lumen Technologies aimed to enhance video delivery in challenging markets like Eastern Europe, Asia Pacific, and Latin America. Some sources suggest Streamroot’s technology may still be integrated into Lumen’s CDN offerings, but no clear evidence confirms active use. Conflicting reports exist about its revenue and status at the time of acquisition, with estimates of sub-$5M in annual revenue in 2019.
