CDN is the abbreviation of Content Delivery Network. It is designed to avoid bottlenecks and aspects that may affect the speed and stability of content transmission over Internet, to improve the transmission. By placing node servers on the network to make up the a tier of smart virtual network based on the existing Internet, the CDN system can redirect the user requests to the service node which is closest to the user in real time based on information such as network traffic, node connectivity, workload, distance with a user and response time. In doing so, users can access content that is closest to them, solve Internet congestion and accelerate user access.

We maintain long-term cooperative relationship with China’s major telecommunication carriers. With the principle of “optimizing network deployment and promoting end-user experiences,” 21Vianet has built a multi-layer distributed network platform composed of large, medium and small cities, and owns more than 10,000 square meters of carrier-class data centers in Beijing, and an additional 50,000 square meters in other regions of China.

What is the standard in IT service management and what are the advantages in applying this standard?
The Information Technology Infrastructure Library (ITIL) is the most popular standard in IT service management, and is used throughout 21Vianet’s facilities.
ITIL also applies to IDC’s. Historically, the services provided by an IDC were difficult to measure and evaluate resulting in customers not knowing whether they had the services as promised in their contracts. Today, ITIL provides an objective, strict and qualitative standard for measuring the quality of services provided.
The ITIL is applied in cooperation with the former routine processes of operation and maintenance in data centers.
Since data centers and hosting services’ management processes are well established, (i.e. the process of entering or exiting of data centers, the process of introducing new equipment, etc.) ,ITIL measurements have become standard operating procedures throughout our facilities. This has standardized the management of our data centers, dramatically increasing our overall efficiency.
How is the hosted equipment properly managed and what are the customer benefits?
The data center utilities IBM MAXIMO for managing our hosted equipment. MAXIMO is the most widely used system for managing server equipment in IDCs. It manages equipment information, like brand, type, serial number, as well as region, data center, and even specific rack. This system allows us to efficiently maintain the quality of our equipment.
We also have an established process for serving our accounts, including establishing the need, approving the process, conducting the work closing the process and recording any transfer of property.
What technical support can be provided in the data centers to resolve customer issues?
Data centers provide substantial assistance and support to resolve any issues that customers may face, including:
1) Installation and connection of networking equipment, which includes establishing the hardware environment after customers provide their requirements.
2) One-time installation of network systems include establishing common operating systems, application software, network software, anti-virus software, databases, and firewalls.
3) Other local supporting services include 24/7 solutions support which helps address any customer questions or concerns.
4) Emergency management procedures which include:
- Malfunctions monitoring and early-warning mechanism: Predictive monitoring system enabling early warning system to sound when potential equipment malfunctions or safety issues arise.
