[photopress:China_Cache.jpg,full,alignright]ChinaCache is the first and biggest Chinese provider of Content Delivery Network (CDN) service. CEO Wang Song recently announced the completion of the company’s second round equity financing totaling $31.5 million and that the total network capacity reached 200Gbps last month.
Wang Song said, ‘About 60% of the funds will be used to strengthen the company’s efforts in research and development and accelerate its system expansion. And our network capacity will continue to increase after reaching 200Gbps, every week the capacity increases by 10Gbps. We will reach 300Gbps capacity in the near future.’
So what is Content Delivery Network (CDN)? Content Delivery Network (CDN) is a term that was coined in the late 1990s to describe a system of computers networked together across the Internet that cooperate transparently to deliver content (especially large media content) to end users.
CDN nodes are deployed in multiple locations. These nodes cooperate with each other to satisfy requests for content by end users, transparently moving content behind the scenes to optimize, speed up, the delivery process. Optimization can take the form of reducing bandwidth costs, improving end-user performance, or both.
Wang Song put it another way. He said CDN is a virtual network that covers the Internet and distributes information to nodes in different areas. For example, if a Beijing web user wants to check a Shanghai-based website, he will encounter low speeds due to the basic structure of network of the two regions.
But with CDN, the Shanghai website information will be delivered to the server closest to the user, from which the web surfer can get what he wants much more quickly. And the bigger the network capacity is, the higher the speed will be.
Wang Song said, ‘CDN is seen as a responsible courier, and what our company does is set up servers in many Chinese cities and rent them out to various websites, so that they do not need to spend a huge amount of money to settle servers by themselves. They can pay us to do this for them since we have over 170 of them in more than Chinese 50 cities.’
He said in the United States, a new CDN company named Limelight is booming by serving websites offering online videos and becoming a strong competitor to another rival CDN company called Akamai.
Wang Song said, ‘We have learnt from this and began to cooperate with video websites like Tudou.com in China to get the market before those other smaller CDN companies. We are happy to accept their challenges in the future.’
