P2P Content Distribution Network (English name: P2P CDN, hereinafter referred to as PCDN) is a low-cost, high-quality content distribution network service based on P2P technology and constructed by mining and utilizing the massive fragmented idle resources of the edge network. You can access this service by integrating PCDN SDK (hereinafter referred to as SDK) to obtain distribution quality equivalent to (or slightly higher than) CDN, while significantly reducing distribution costs. Suitable for business scenarios such as video on demand, live broadcast, and large file downloads.

What are the special features of PCDN?

First, comprehensive support

Provides a powerful and easy-to-use SDK, supporting Android / iOS / OTT / Flash On-demand, live broadcast, and large file download services under other platforms have unified interfaces and simple adaptation to each terminal platform;
