비디오 서버에 저장된 비디오 데이터를 유한한 버퍼 크기를 가진 많은 클라이언트에게 전송하기 위해 데이터전송률 변경 횟수, 첨두 전송률, 전송률 변화량과 같은 요소를 고려한 전송 계획이 필요하다. 이러한 전송 계획을 스무딩 알고리즘이라고 하며 CBA, MCBA, MVBA 등이 있다. 본 연구에서는 첨두 전송률 이용률을 감소화하기 위한 알고리즘을 제안하고 제안된 알고리즘의 성능을 평가한다. 평가 요소에는 전송률 변화 횟수, 첨두 전송률, 전송률 변화량, 버퍼 이용률, 평균 전송률, 첨두 전송률 이용률을 사용한다. 평가 결과, 제안된 알고리즘은 MVBA 알고리즘보다 낮은버퍼 활용률과 평균 전송률, 첨두 전송률 이용률을 보인다.
Abstract
The transmission of video data stored on a video server to a large number of clients with finite buffer sizes requires a transmission plan that considers factors such as the number of rate changes, peak rate, and the amount of rate variability. Such transmission plans are referred to as smoothing algorithms, examples of which include CBA, MCBA, and MVBA. This study proposes an algorithm to reduce the utilization of the peak rate and evaluates the performance of the proposed algorithm. The evaluation factors include the number of rate changes, peak rate, rate variability, buffer utilization, average rate, and peak rate utilization. The evaluation results show that the proposed algorithm exhibits lower buffer utilization, average rate, and peak rate utilization compared to the MVBA algorithm.
