초록

P2P(peer-to-peer) 모델은 클라이언트-서버 모델의 서버 링크 병목현상을 해결하기 위한 대안으로 고려되고 있다. 본 연구에서, 우리는 P2P 네트웍에서 연속형 미디어의 배포 문제 중 두 가지를 다루었다. 첫째는 다중-소스 스트리밍 세션을 위한 미디어 데이터의 전송 스케쥴링 문제이다. 버퍼링 지연을 최소화시키는 정교한 분산 전송 스케쥴링으로서FSS(fixed-length slotted scheduling)라는 기법을 제안한다. 두 번째 문제는 스스로 성장하는 P2P 시스템에서 미디어 컨텐츠의 배포 속도 향상 문제이다. 이를 위해 우리는 시스템의 스트리밍 용량이 증가하는 속도를 가속시키는 FAST라 불리는 기술을 제안한다.

A peer-to-peer model is very useful in solving the server link bottleneck problem of a client-server model. In this work, we discuss the problems of distributing multimedia content over peer-to-peer network. We focus on two problems in peer-to-peer media content distribution systems. The first is the transmission scheduling of the media data for a multi-source streaming session. We present a sophisticated scheduling scheme called fixed-length slotted scheduling, which results in minimum buffering delay. The second problem is on the fast distribution of media content in the peer-to-peer system that is self-growing. We propose a mechanism accelerating the speed at which the system's streaming ca-pacity increases, called FAST.
