基于播存结构的雾架构内容协同分发机制
COLLABORATIVE CONTENT DISTRIBUTION MECHANISM IN FOG COMPUTING ARCHITECTURE BASED ON BRAODCAST STORAGE STRUCTURE
摘要
Abstract
Fog computing is a computing paradigm that pushes cloud services to the user's edge.It mainly accelerates content distribution through the method of users' passively pulling content,and lacks active push capacity.Therefore,we propose to use the active push with strong broadcast structure to assist the fog computing architecture and to achieve the active push of the content.Then,a collaborative content distribution mechanism based on software definition is proposed for distributed content distribution,which includes multi-granularity cooperative storage mechanism,software definition strategy and multi-node cooperative strategy in the domain.Finally,the prototype system was used for the experimental test and result analysis.The result reveals that the mechanism can reduce the user request delay and improve the user experience.关键词
