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. CDN node is also often asked by users, today to introduce you about the knowledge of CDN node.

What is the cdn node? Cdn node is a concept put forward relative to the complex structure of the network, which refers to the network node with less intermediate links from the end-user access, and has better response ability and connection speed to the end-access users. Its function is to save the web content and objects with a large number of visits on the dedicated cache equipment at the front end of the server, so as to improve the speed and quality of website access.

Cdn node, also known as edge node, Cache node and so on.

Cache cache memory is a special memory subsystem in which frequently used data is copied to facilitate fast access. The cache memory of the memory stores the contents of frequently accessed RAM locations and the storage addresses of these data items. When the processor references an address in the memory, the cache checks to see if the address exists. If the address is stored, the data is returned to the processor; if the address is not saved, regular memory access is performed. Because cache memory is always faster than the main RAM memory, cache memory is often used when the access speed of RAM is lower than that of microprocessors.

The CDN node is the server used for caching.

Provide proximity responses to end Internet users through widely distributed cache nodes. Through the control of the global load balancing DNS, the user's request is kept from the original server to the Cache server. Because it is closer to the user, the response time must be faster.
