A model based on crossed cubes for VoD services

Content distribution schemes for Video on Demand (VoD) systems, based on the peer-to-peer (P2P) technology, have attracted more and more attention. Recently, people mainly focus on the latency performance, security, interaction, scalability, and so on. We propose a new network topology model - Similarity Crossed Cube(S-CQ for short), which combines with the feature of crossed cube and establishes multiple independent spanning trees for data distribution in the layer. This network model processes the properties such as good self-organization, delay, etc. The simulation results also show that it can effectively reduce the playback delay and maintain a low delay. The S-CQ network model can provide good quality of VoD service and effectively improve the user experience.
