Cdn access record of large website acceleration traffic package? With the boom of live video, on-demand video and short video, the number of users continues to increase significantly. As a general basic network, cdn can accelerate user terminals to access web pages, images, videos, files and other content through wireless and fixed broadband access networks. At present, using content distribution network (cdn) to accelerate network video services has become a key fulcrum to support the rapid development of network video services.
Cdn (Content Distribution Network) is an overlay network built on the basic ip bearer network. It is oriented to streaming media, web and application content transmission, and has the ability to automatically distribute content and centrally schedule and control traffic. At first, cdn mainly carries static web content, and then cdn accelerates dynamic web content. With the development of digital video technology and the rapid increase of Internet bandwidth, video content on the Internet is gradually enriched. The second generation cdn is mainly for Vod, streaming video and audio distribution services. With the development of streaming media technology, live streaming media has become the service content of cdn content distribution.
The logical architecture of cdn network can be divided into three layers: scheduling control layer, content center layer and service node layer. The dispatching control layer is responsible for the unified dispatching of user requests, cdn network management and business operation management, mainly including the operation management center and the dispatching control center. The content center layer implements the docking and content injection of the contracted CP/sp (Content Provider/Service Provider) system through the content center, and provides content distribution and return services for edge service nodes; The service node layer is composed of edge service nodes, which provide content services for user terminals, and has content caching and media service functions. It is deployed at different levels of the network in a hierarchical architecture.

The voice card rack of telecom network standard network server shall be used to display the service items. The wood floor load of the computer room should meet the requirements of the load design scheme of the telecommunications network computer room. The overall seismic rating is more than about 8, and some special machines and equipment can be shown to customers. In the computer room, customers should be prevented from entering the hosting area as much as possible, and full-time personnel should be responsible for environmental sanitation every day to prevent dust from harming the network server
2. To rent a good Hong Kong cabinet hosting machine room for Internet security, it is necessary to ensure that the customer's network server can access the Internet technology quickly and smoothly, and can select excellent high-end wireless routes by referring to our Hong Kong Xintiandi machine room. The high-speed and reliability of the Internet can be reasonably guaranteed by connecting the backbone nodes of China's Internet technology through the high-speed optical fiber line security channel.
3. The power engineering ensures that the machine room rented and managed by the cabinet in Hong Kong can be equipped with a special distribution station. The switching power supply is transmitted from the power station here in two steps. Different transformers [Taizhou BGP] are connected to each other, so that all transformers can bear all IDC loads. This can ensure that the power supply system can supply power continuously.
4. Guarantee of natural environment All doors and windows of the port cabinet machine room rented and managed shall be sealed to avoid the impact of dust, noise and other external factors. The size of the entrance and corridor can meet the transportation requirements during the installation of the system software. Wood floor shall be anti-static and have high compressive strength. The raw materials for the ceiling decoration of the machine room meet the fire safety requirements, sound absorption materials with good sound insulation and noise reduction,
5. The security assurance server port network contains a large number of customer statistics, so the computer room must display security assurance. The machine room can be equipped with a TV monitor and an automatic control system for entering and exiting the machine room to ensure that no monitoring blind area can be found in all buildings.
