Founded in 1998, ChinaCache is one of the earliest CDN providers in China. The company has a large coverage of mainland China, with additional points-of-presence (PoPs) in the rest of the world. The CDN services of ChinaCache are exploited through different divisions, such as NovaCDN and Webluker.
ChinaCache has a 120 points of presence (PoPs) in mainland China, in all major cities and regions of the country. They service well-known brands such as Big Fish Games, Uber, LinkedIn, Coach, Intel and Adobe.
Businesses operating their website in China require an Internet Content Provider (ICP) license. While not mandatory, Chinese Internet Service Providers are required to restrict access to sites without such a license. ChinaCache provides business with support to obtain an ICP license.
ChinaCache has offices in Hong Kong, Beijing, London and the US.
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.
