流媒体分发系统中基于流量管理的内容路由方法

Method for Content Redirection Based on Traffic Management in Multimedia Distribution System

现有流媒体分发系统中流量管理和内容路由过程彼此独立,无法获得系统性能的最优解。在深入分析现有流量管理和内容分发过程的基础上,提出一种基于流量管理的内容路由方法。该方法中互联网内容提供商实时从服务提供商处获得拓扑及流量信息,实现内容路由过程的联合协同求解以最优化内容路由性能,从根本上实现了互联网内容提供商和服务提供商利益的最大化。

Current traffic management and content redirection in multimedia distribution network are implemented independently, leading to the sub-optimization of system performance. Based on analysis of above two models, this paper provides a content redirection method based on traffic management. With the method, the content provider can get topology and traffic information from the service provider in real-time, and solves the content distribution problem based on cooperation, which can optimize the content distribution model and then maximize benefits of both Internet service providers and content providers.
