Abstract:

With the development of broadband network technology and service,as well as the increasing of people's requirement to video communication service,video communication technology has been studied quickly.In this paper,firstly the characters of current video communication solutions had been studied and compared.Then we proposed one solution of video communication based on content delivery network technology and system,which has low system cost,better scalability and higher video quality.Also the architecture,processing and advantage analysis of this system were described in this paper.Lastly we developed one testing system in real network,and got some initial results.

Key words: video communication, content delivery network, live streaming
