Founded in 1997, Mirror Image Internet is a seasoned service provider with a large portfolio of web and hosting services. The company is principally owned by Xcelera Inc., and is headquartered in Massachusetts, US and has an European sales office in London.
The network map of Mirror Image is not made public on their website, and there is no information on the number of points-of-presence (PoPs). Based on performance comparisons, we think Mirror Image uses the Highwinds network, and add their own intelligence. Note that Mirror Image uses the term “Content Access Point (CAP) facilities” to refer to their PoPs.
Mirror Image Internet hold a variety of patents to protect its core technology. These concern Internet communication, web serving and the distributed selection of content servers.
The company offers features for video streaming and video-on-demand (VOD) through their miPUBLISHER platform. Large file download is also supported. Their control panel ClearVue Control Center includes real-time analytics and the necessary tooling to manage the CDN.
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.
