Tata Communications, a company of Indian multinational Tata Group, offers a CDN service with 400 points-of-presence (PoPs) on five continents, in 21 locations. Tata owns and operates an impressive network infrastructure, with their sub-terrestrial and sub-sea network spanning 700,000 kilometers - more than 17 times around the world. According to the company, 24% of the planet’s internet routes are on their network, which grants improved performance and flexibility.
In 2011, Tata Communications acquired BitGravity - a US-based CDN provider founded in 2006. BitGravity. The companies had been in a strategic alliance leading up to the acquisition, and the move was a logical next step for Tata Communications to improve its global CDN offering. Remnants of BitGravity can still be found, such as the Tata Communications CDN support portal.
Tata Communications offers a wide range of CDN features such as live streaming and video-on-demand (VOD), an out-of-the-box online video platform, site acceleration and software delivery. They also provide DDoS and security services, hosting, colocation and transit.
Limelight Networks is an Arizona-based CDN provider that owns and operates its own content delivery network. The company was founded in 2001 and has offices in the US, Europe and Asia.
Limelight offers regular CDN services for static content, website acceleration, video streaming (Limelight Orchestrate) and cloud storage. Some of the services in the Limelight portfolio came to be from a variety of acquisitions done by the company in the past. Acquired companies include AcceloWeb (website acceleration), Kiptronic (video) and Delve Networks (video).
In 2006, the CDN provider was sued by Akamai Technologies, Massachusetts Institute of Technology (MIT) and later by Level3 over alleged patent infringements. In 2015, after a long string of decisions, came an end to the back-and-forth between Akamai and Limelight: Limelight was held liable for direct infringement of an Akamai-held patent by the US Court of Appeals for the Federal Circuit. In response to the ruling, Limelight Networks (NASDAQ:LLNW) fell greatly.
As of today, Limelight is still fighting a portion of the August 2015 decision, prolonging an already long-standing dispute against Akamai.
Limelight serves, or has served notable customers such as Disney, EA Sports, MySpace, Harpo Productions, MTV, Nintendo, Heineken and Carrefour. With the exception of the latter two, these customers are seemingly no longer with Limelight.
