Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, and is composed of server groups of edge nodes distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Many users will be more concerned about the main advantages of CDN when they actually use it.

What are the cdn services?

At present, the competition of cdn service providers has gradually replaced "price" by "technology", and technology has become a key factor for manufacturers. At present, cdn technical services are divided into stable, all-round, performance and other categories according to their emphasis.

Stabilizers

CDN service should maintain the stability of content distribution and strengthen the accumulation of technologies such as integration technology, weak network acceleration technology, service quality performance fluctuation monitoring and intelligent fault diagnosis, rather than deliberately pursuing the latest special effects. For example, when customers have hotlink protection updates, they can inform customers as soon as possible and reduce the impact of failures, which is more attractive in live and short video scenarios such as competitions and concerts.

Omnipotent faction

Provide complete end-to-end solutions for live broadcast and VOD, in addition to CDN services, including domain name registration, website development, IDC, cloud communications, mobile services, cloud security, monitoring and management and other integrated one-stop services.

Performance school

Through self-developing core, optimizing node selection and network deployment, we can achieve the goal of improving performance while taking into account the stability. Even if the overall network speed is increased by 0.1 second, it is necessary to improve the response speed of the core Cache, improve the response speed of the scheduling system, reduce the delay of network nodes, increase the download speed, and reduce the distance between network nodes and users. The performance improvement of a single link can meet the stringent requirements of live streaming and short video platforms for CDN.

The above is an introduction to the categories of cdn services.
