The full name of CDN is content IBuySpy receptacle, that is, contents distribution network. The goal is to add a new layer of network architecture to the existing Internet, publish the content of the Web site to the nearest user's network "edge", so that users can get the required content, solve the Internet congestion situation, improve user access to the Web site response speed. The problem of slow response of users visiting the website due to the small network bandwidth, the large amount of users ' access and the uneven distribution of the Web site are comprehensively solved from the technology.

CDN Internet Content Publishing Network (IBuySpy Receptacle) CDN Technology is an effective means to solve the problem of poor Internet performance in the United States in recent years. The basic idea is to avoid the Internet as far as possible to affect the speed and stability of data transmission bottlenecks and links, so that content transmission faster and more stable. By placing node servers across the network, a layer of intelligent virtual networks based on the existing Internet, the CDN system can redirect the user's request to the nearest service node according to the network traffic and the connection of each node, the load status and the user's distance and response time.

In fact, the Content distribution network (CDN) is a new type of network construction, it is to be able to distribute broadband rich media in the traditional IP network to optimize the coverage layer, and from a broad perspective, CDN represents a quality and order based network service model. Simply put, Content Publishing Network (CDN) is a strategic deployment of the overall system, including distributed storage, load balancing, network request redirection and Content Management 4 elements, while content management and global network traffic Management (traffic Management) is the core of the CDN. Based on user proximity and server load judgments, CDN ensures that content is serviced in a very efficient manner for the user's request. In general, content services are based on a caching server, also known as proxy caching (surrogate), located on the edge of the network, away from the user only "hop" (Single Hop). At the same time, the proxy cache is a transparent mirror of the content provider's source server, usually located in the data center of the CDN service provider. Such a framework allows CDN service providers to represent their customers, the content provider, to provide the best possible experience to end users, who cannot tolerate any delay in response time. According to statistics, the use of CDN technology, can handle the entire Site page 70%~95% content access, reduce the pressure on the server, improve the performance and scalability of the site.

CCDN is the CDN management system of CDN Studio, it is a popular website acceleration and caching system, which combines intelligent analysis with CDN. CCDN is a secure and stable system platform based on Linux platform using the latest CDN2.0 technology.

Use the CCDN management system to make your site fast and super safe right-hand, CCDN management with business, government, schools, financial institutions and special protection. A Hugh has the following points.

1, the protection of Web site source server IP address.

Using the CCDN website to accelerate the system, users need only do one step simple domain name resolution, you can complete the Web site cache acceleration, user operation simple, fast, security features, do the analysis, the customer visit the site when the first access to the Web site through the CDN node to visit the root server, to ensure the security of the source server, Also reduces the background server bandwidth pressure, safe and fast double-edged sword.

2. Accelerate the service of the region

Using the CCDN management system to provide a regional accelerator for each site, domestic now know, netcom to telecommunications access speed is not ideal, regional and regional speed, bandwidth differences, CCDN just solve this problem, using the National CDN node system, let your website visit our nearest CDN node, Let your fast access, for example, you are Beijing Telecom users, we in Beijing Telecom to place a CDN node, your site in Shanghai, so using our CCDN to achieve localized acceleration services.

3. Optimize Server Bandwidth

Now portal sites, video sites, interactive sites, bandwidth pressure increased dramatically, forcing users to use a dual-line server to reduce server pressure, for individual users often use dual-line server also solve the pressure of bandwidth, in this case, CCDN management system through distributed CDN nodes, To achieve a more than one of the bandwidth pressure reduction, greatly reduce the pressure of the background server.

4, high hair can engage in cluster-type attack ability

Because of the many domestic CDN nodes plus network Intelligent redundancy measures, can effectively defend the CC, DDoS attacks, while ensuring the security of the backend server.

CCDN Management System fully consider the current user needs of the important situation, in a number of users strongly request the development of CDN Management system platform, so that every user using CDN can try to bring us a faster access speed and high security protection capabilities.

Compared with the existing Content release mode, CDN emphasizes the importance of network in content publishing. By introducing active Content management and global load balancing, CDN is fundamentally different from the traditional content release mode. In the traditional content release mode, the release of content is completed by the ICP Application server, and the network is only a transparent data transmission channel, this kind of transparency shows that the quality assurance of the network stays at the level of the packet, but cannot differentiate the service quality according to the different content objects. In addition, because the IP network's "best effort" characteristics make its quality assurance relies on the user and application server end-to-end to provide sufficient, much more than the actual required bandwidth to achieve. In such a content release mode, not only a large number of valuable backbone bandwidth is occupied, and the ICP Application server load also becomes very heavy, and unpredictable. When some hot events occur and surge flow occurs, local hotspot effect is generated, which causes the application server to overload and exit the service. Another drawback of this central-based application server's content publishing model is the lack of personalized services and the distortions in the value chain of broadband services, and content providers are taking on content publishing services that they should not do or do poorly.
