A Study of Enhancement in Virtual Content Distribution Network

In this paper, we will focus on virtual content delivery network (VCDN) that each service provider own their independent service delivery and distribution network virtually. The VCDN system is a key technology for adding flexibility to CDNs. We propose VCDN system with rateless codes to avoid computational overhead and limit increase of the streaming delay. The proposed system builds a multi-tree structure that minimizes the source transmission rate and reduces content distribution time by using rateless codes.
