Abstract

We develop architecture of a virtual aggregation gateway (VAG) which enables composite application streaming based on N-Screen-as-a-Service (NaaS) using cloud computing in thin-client environment. We also discuss the problem of server computing burden in large scale multi-client case for screens sharing with composite application streaming over the internet. In particular, we propose an efficient Framework of N-Screen Session Manager which manages all media signaling that are necessary to deliver demanded contents. Furthermore, it will provides user with playback multimedia contents method (TV Drama, Ads, and Dialog etc) which is not considered in other research papers. The objectives of proposing N-Screen Session Manager are to (1) manage session status of all communication sessions (2) manage handling of received request and replies (3) allow users to playback multimedia contents anytime with variety of devices for screen sharing and (4) allow users to transfer an ongoing communication session from one device to another. Furthermore, we discuss the major security issues that occur in Session Initiation Protocol as well as minimizing delay resulted from session initiations (playback or transfer session).

본 논문은 씬클라이언트 환경에서 클라우드 컴퓨팅을 이용하여 N-Screen-as-a-Service(NaaS) 기반하여 통합 된 어플리케이션을 스트리밍하기 위한 Virtual Aggregation Gateway(VAG)를 제안한다. 또한, 본 논문에서는 인터넷을 통하여 대용량 멀티 클라이언트에서의 융합된 어플리케이션 스트림의 화면 공유 시 서버 측 문제에 대해 기술한다. 특히, 콘텐츠를 전달하기 위해 가능한 모든 미디어 시그널링을 효율적으로 관리를 하는 N-Screen 세션 관리자 프레임워크를 제안한다. 더 나아가, 사용자들에게 재생 멀티미디어 콘텐츠 (TV 드라마, 광고, 대본 등)를 제공한다. 제안한 N-Screen 세션 관리자의 목표는 다음과 같다. (1) 모든 통신 세션의 세션 상태를 관리 (2) 수신된 요구사항이나 답변들의 제어를 관리 (3) 사용자들에게 언제 어디서든 이기종 단말에 화면을 공유하면서 멀티미디어 콘텐츠를 재생 그리고 (4) 사용자들이 진행 중인 통신 세션을 이기종 단말로 전환을 가능하게 해준다. 마지막으로, Session Initiation Protocol (SIP)에서의 보안 문제점 및 재생 혹은 전송 세션에서의 지연을 최소화 하는 것에 대해 기술한다.
