초록

다양한 방송사와 서로 다른 CP(Contents Provider)가 분산되어 있는 Data Center서버에서 VOD 서비스를 하고자 할 때, 서로 다른 CP 플랫폼들이 고화질 HD, 3DTV 비디오 등의 영상파일을 교환하기 위해 고성능 네트워크를 통하여 빠르게 전송할 수 있는 망을 빠르게 구성해야 한다. 본 논문은 Public망의 QoS와 보안성을 보완하는 선택적인 암호화 방안을 이용하여, 고속의 안전한 VPN(Virtual Privatr Network)을 생성하고 콘텐츠를 고속으로 대용량 영상파일을 전송하는 프로토콜을 제안한다. End to End의 Device가 대용량의 영상파일을 Parallel 전송으로 가용한 자원을 최대한 사용하면서 안전한 콘텐츠 전송이 가능한 고성능의 VPN을 구성하는 모델을 제안한다.

When broadcasters want immediately a variety of VOD files in a distributed server of them data centers and away contents provider, CPs of different platform to exchange high-quality HD, 3DTV video and other video files over the IP networks of high-performance that can be transferred quickly and must be configured quickly. This paper, by using an optional encryption method to complement a QoS and security of public network, suggests high speed and secure content transmission protocol such as VPN(Virtual Private Network) for large video files and big data. As configured high performance VPN, end to end devices use the best of available resources over public network by parallel transfer protocol and the secure content delivery network.
