1) reduce the bandwidth usage of servers and web servers. By using a CDN service, users can access the main distribution channels (including pages and pictures) in the CDN node. This reduces the pressure load and bandwidth resources on the source device, save resources and bandwidth consumption to the same services, such as e-mail, forums and server resources to ensure the safety of the site. In expanding the scale to ensure the quality of service.
2) improve responsiveness to different areas of the site the user visits. Existing CDN network nodes are distributed in Telecom, Netcom, China Mobile, China Railcom, education network and other major domestic ISP network to ensure that the contents of users in different networks around the country can be fast and stable access to the site. Access to quality degradation avoid bandwidth bottlenecks between different network operators caused.
3) to solve the problem of large-scale centralized access, users are at the same time. The case CDN service network processing power and high-bandwidth storage node server, you can ensure burst access, access to quality Internet users, to attract users to provide good quality service, when a site visit at the peak.
4) unique dynamic acceleration services can improve access speed BBS and other dynamic content.
5) is transferred from the source station to access the CDN network, a variety of network attacks, including DDoS attacks, will effectively prevent, thereby improving network security site.
