In 2014, Comcast debuted their CDN service. With their own CDN in place, Comcast can deliver a better experience to their already existing consumer base. Unique in the CDN landscape, we can label Comcast a B2C CDN service provider.
As the ISP, cable owner and CDN provider, Comcast is able to offer an excellent SLA and potentially lower pricing, when compared to 3rd party CDN providers who do not own the network they operate on.
The Comcast CDN is regional and offers PoPs within the US only. The CDN service is therefore not suited for businesses with a global userbase, unless it is combined with other CDN providers in a multi-CDN setup. Warpcache is a multi-CDN provider that offers the Comcast CDN in combination with others.
Comcast is a very suitable provider for a multi-CDN setup. Warpcache resells multiple providers, both in an integrated multi-CDN solution and separately.
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.
