What does pcdn mean?

Pcdn is a P2P content distribution network.

P2P content distribution network (English name: P2P CDN, hereinafter referred to as PCN) is a low-cost and high-quality content distribution network service based on P2P technology, which is built by excavating and utilizing the massive fragmented idle resources of the edge network.

The basic idea is to avoid bottlenecks and links that may affect the speed and stability of data transmission on the Internet, so as to make content transmission faster and more stable. By placing node servers everywhere in the network, an intelligent virtual network based on the existing Internet is formed.

CDN system can redirect the user's request to the nearest service node in real time according to the comprehensive information such as network traffic, connection of each node, load state, distance to the user, response time, etc. Its purpose is to let users get the required content nearby, solve the Internet network congestion, and improve the response speed of users visiting websites.

You can access the service through the integrated PCDN SDK (hereinafter referred to as SDK), and get the same (or slightly higher) distribution quality as CDN, while significantly reducing the distribution cost. Suitable for business scenarios such as video on demand, live broadcast, and large file download.

Features of PCDN:

Millions of service nodes (including more than 500 backbone nodes and millions of peripheral nodes) have been deployed throughout the country, integrating CDN and P2P technologies to realize multi-level network acceleration.

Independent research and development of the industry-leading node scheduling system, with 100+ core technology patents, to achieve global scheduling of millions of nodes, the optimal path to complete data transmission, close access, and ensure the quality of delivery services.

At the same time, it supports a variety of content caching methods, such as automatic discovery caching mechanism and manual pre-pushing mechanism of user hot content.

Giving full play to the characteristics of P2P technology has obvious advantages in parallel transmission, weak network optimization and download acceleration.
