ChinaNetCenter is one of the leading Chinese Internet service platform providers that offers both coverage of mainland China and in the rest of the world. ChinaNetCenter was founded in 2000 and was listed on the Shenzhen Stock Exchange in 2009. Its US subsidiary MileWEB was set up in 2012 and tasked with globalising ChinaNetCenter’s CDN services. Global sales operations followed in 2014 and MileWEB was renamed to Quantil.
The company has over 500 ‘CDN nodes’ in mainland China, covering all the major cities. Another 60 of these CDN nodes, what we assume are PoPs, are located in Europe and the United States. Next to CDN services, ChinaNetCenter offers server hosting and rental.
Features or products offered by ChinaNetCenter include the usual, such as download delivery, site acceleration, mobile acceleration and media streaming.
Note that international businesses require an Internet Content Provider (ICP) license to operate their site from China. Most Chinese CDN providers such as ChinaNetCenter and Quantil offer support to clients applying for the ICP license. Mind that without a license, Chinese ISPs are required to restrict access to the website.
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.
