P2P Live Streaming Distribution System with Fast Content Switching and Category-Based Recommendation Function

Live streaming distribution services have spread as one of the most popular services. The technique of creating contents has been developed, and users can use it easily. Accordingly, the number of contents rapidly increased. In the existing content distribution system, users must select an interesting content from a large amount of contents in the Internet. It takes long time to find out the most interesting content. Moreover, when they switch to other content, it takes long delay because they need a procedure of joining another distribution network anew. Thus, the system which helps users view satisfied contents and provides fast content switching service is needed. In this paper, we introduce a dedicated server to help users switch to another desired content. We also propose the system which recommends real-time contents on the basis of category information and provides fast content switching service by maintaining reserved peers in advance. Our simulation results show that the proposed system can provide satisfying contents to all users with short delay.
