Abstract

Such problems as delay, congestion, and crosstalk in the proxy system degrade not only QoS (Quality of Service) but responsiveness and reliability of the streaming media service. To solve this problem this paper proposed a FRTP (Fuzzy Relevance-based Transcoding Proxy) mechanism. The proposed FRTP mechanism analyzes fuzzy similarity for partitioned segment versions of media objects to create a FRTG (Fuzzy Relevance-based Transcoding Graph). Created FRTG determines the transcoding for partitioned media object segment versions. Determined transcoding improves DSR (Delay Saving Ratios), CHPR (Cache Hit Precision Ratio), and CHRR (Cache Hit Recall Ratio). The proposed mechanism is simulated to evaluate such performance parameters as DSR, CHPR, and CHRR. Simulation results shows that the proposed mechanism outperforms in DSR, CHPR and CHRR compared with the other existing mechanisms.

프록시 시스템에서 지연, 혼잡, 간섭 등의 문제는 QoS(Quality of Service)를 떨어뜨릴 뿐만 아니라 또한 스트리밍 미디어 서비스의 응답성과 신뢰성을 떨어뜨린다. 본 논문에서는 이러한 문제를 해결하기 위하여 새로운 퍼지적합도 기반의 트랜스코딩 프록시 FRTP(Fuzzy Relevance-based Transcoding Proxy) 메커니즘을 제안한다. 제안된 FRTP메커니즘은 미디어 객체의 분할된 세그먼트 버전에 대한 퍼지 적합도를 분석하며, 분석된 퍼지 적합도에 따라 퍼지 적합도 트랜스코딩 그래프 FRTG(Fuzzy Relevance-based Transcoding Graph)를 생성한다. FRTG는 분할된 미디어 객체 세그먼트 버전들에 대한 트랜스코딩을 결정하게 되며, 결정된 트랜스코딩은 세그먼트 버전들 사이의 지연절약율 DSR(Delay Saving Ratios), 캐시 히트 정확률 CHPR(Cache Hit Precision Ratio), 그리고 캐시 히트 재현율 CHRR(Cache Hit Recall Ratio)을 향상시키게 된다. 제안된 기법의 성능을 알아보기 위하여 DSR, CHPR, 그리고 CHRR의 성능을 평가하였으며, 그 결과 제안된 기법이 비교 기법들에 비해서 DSR, CHPR, 그리고 CHRR의 성능이 향상됨을 알게 되었다.
