Abstract

This paper presents a design and implementation method of living streaming system based on multi-service nodes collaboration. The system uses the entropy weighting method to dynamically determine the weight factor of each service node and uses the coordinator node to collect the load information of service nodes and perform global optimal distribution of loads. The collection terminal uses RTMP (Real Time Messaging Protocol) as the push protocol to send videos to service nodes, which then transcode the received videos into HLS (HTTP live streaming) and forward them to the releasing nodes in real time. Users can watch live videos on the releasing nodes. This service model is particularly suitable for watching live videos on mobile terminals. Herein, the design and implementation of the proposed system is described and its feasibility and effectiveness are verified in actual network environments.
