초록
본 논문에서는 Hybrid CDN/P2P 구조를 기반으로 최적화된 미디어 데이터 탐색과 전송을 수행하며 사용자의 요청 가능성 예측을 통한 선별적 저장을 통해 사용자로의 끊김없는 데이터 전송과불필요한 트래픽의 감소를 가능하게 한다. 또한 전송지연 및 패킷 손실의 가능성을 최소화하여실시간으로 미디어를 활용할 수 있도록 하는 새로운 미디어 관리 기법을 제안한다. 이를 위해 각미디어를 논리적인 세그먼트로 나누어 구성하고 각 세그먼트에 대한 가중치를 지속적으로 계산하며 계산된 가중치에 따라 세그먼트 데이터의 저장 여부를 결정하도록 한다. 또한 네트워크상에산재되어 있는 컴퓨팅 노드들을 거리에 따라 지역적 그룹으로 지정하고 해당 그룹 내에서 저장공간을 효율적으로 공유하고 활용하도록 한다. 제안하는 기법의 효율성을 검증하기 위해 수행된실험을 통해 제안하는 방식이 기존의 방법들에 비해 비교적 좋은 성능 평가가 도출되는 것을 확인하였으며 이는 전송과정에서 발생되는 초기 지연시간 감소와 끊김 없는 전송 모두를 가능하게할 수 있음을 알 수 있다.
Abstract
In this paper, optimized media data retrieval and transmission based on the Hybrid CDN/P2P architecture and selective storage through user's prediction of requestability enable seamless data transfer to users and reduction of unnecessary traffic. We also propose a new media management method to minimize the possibility of transmission delay and packet loss so that media can be utilized in real time. To this end, we construct each media into logical segments, continuously compute weights for each segment, and determine whether to store segment data based on the calculated weights. We also designate scattered computing nodes on the network as local groups by distance and ensure that storage space is efficiently shared and utilized within those groups. Experiments conducted to verify the efficiency of the proposed technique have shown that the proposed method yields a relatively good performance evaluation compared to the existing methods, which can enable both initial latency reduction and seamless transmission.
