A Study of Enhancement in Virtual Content Distribution Network
Kyoungwoo Heo, Il-Koo Jung, Changwoo Yoon · 2014
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.
