With the rapid development of Internet services, bandwidth costs have become a major part of operating expenses. To save on bandwidth costs, an increasing number of Internet video companies are choosing to use PCDN for content distribution. However, due to a lack of effective control technologies, Peer-to-Peer Content Delivery Networks (PCDN) often severely disrupts network order, leading to a negative user experience. This article proposes a home-based distributed CDN system that integrates operator CDN and network capabilities. It adopts a two-level architecture, innovates terminal multi-connection grouping technology solutions, reduces the construction costs of operator networks and CDNs while ensuring user access quality, and achieves orderly exploitation of home terminal capacity resources.
