P2P架构是近年计算机网络技术发展的重要趋势，越来越向平台化发展，目前在互联网上的很多文件分发平台，都是采用P2P架构进行实现。用P2P技术来构建服务交付平台上的媒体文件分发系统，将节目内容预先进行流化处理后分块存储在多个边缘服务器中，由调度服务器按照就近原则、负载均衡原则进行集中控制，并基于网络状况实时选择和轮换向用户提供流服务的边缘服务器。用户观看一个点播节目时的流服务通常是由多个边缘服务器协同完成的，可以在用户集中点播时将负载在整个网络中更合理地均匀分布，而不会过度集中在某个边缘服务器中，避免边缘服务器拥塞。在数字家庭的服务交付平台下，存在支持P2P传输的终端设备，也存在不支持P2P传输的终端设备。本实施例在混合支持传统C/S架构和支持新的P2P架构的服务交付平台中，提出一种实现媒资业务系统中媒资数据的唯一性管理和高效、稳定、可靠的传输实现方法。
The P2P architecture is an important trend in the development of computer network technology in recent years, and it is becoming more and more platform-oriented. Many file distribution platforms on the Internet are currently implemented using the P2P architecture.

The scheduling server performs centralized control according to the principle of proximity and load balancing, and is based on Network conditions real-time selection and rotation of edge servers that provide streaming services to users. When a user views an on-demand program, the streaming service is usually coordinated by multiple edge servers, which can distribute the load more evenly throughout the network when the user is on-demand, without being excessively concentrated in an edge server. Avoid edge server congestion. Under the digital home service delivery platform, there are terminal devices that support P2P transmission, and terminal devices that do not support P2P transmission. In the service delivery platform that supports the traditional C/S architecture and supports the new P2P architecture, this embodiment proposes a unique management and efficient, stable and reliable transmission implementation method for media asset data in the media asset service system.
