TY - JOUR AU - Yoon, Changwoo AB - Recently, the technology of multimedia content delivery is spotlighted due to many multimedia services. Specially, the needs of a huge content delivery technology is increasing because the period of huge multimedia content creation becomes shorter. The content delivery network (CDN) is a popular solution for distributing a multimedia content using physical resources. However, the CDN cannot provide a flexible service to content providers because of cost issue. In this paper, we aim to build a virtual content delivery network (VCDN) that each service provider own their independent service delivery and distribution network virtually. The proposed VCDN system uses a rateless codes for avoiding computational overhead and limits increase of the streaming delay. The proposed VCDN system builds a hierarchical tree structure that minimizes the time complexity of source nodes and reduces content distribution time by using rateless codes. The proposed VCDN system can support variety of social media services because its flexibility.
