Abstract

In this paper, we address TPS (Triple Play Service) based on E-PON and also develop QoS control function for both directions, which is disadvantage of E-PON. E-PON technology has the configuration suitable for TPS, but relatively the large delay characteristics in upstream, so if QoS control function must be supported to transfer the real time traffic for both directions, E-PON technology can support TPS efficiently. Therefore, in this paper, we address the diverse requirements of quality for TPS, and then develop TPS platform to verify the quality characteristics according to QoS characteristics of each element in real environment based on this. This result will be used to improve the quality of TPS that become conventional in near future. ISP will use this result as the basis in establishing quality reference and as the guidance in developing new system.

본 논문에서는 E-PON 기반 TPS (Triple Play Service)에 대한 연구와 더불어 E-PON의 단점인 양방향 QoS 기능 개발에 관한 것이다. E-PON 시스템은 TPS에 적합한 구성을 가지고 있으나, upstream 지연이 상대적으로 큰 특성을 가지고 있으므로, 양방향 실시간 트래픽 전달을 위한 QoS 제어 기능이 지원되어야만 실제 환경에서 TPS를 효과적으로 지원할 수 있다. 따라서 본 논문에서는 TPS를 위한 다양한 품질 요구사항을 제시하고 이를 기반으로 실제 환경에서 종단간 각 요소들의 QoS 특성에 따른 품질 특성을 검증할 수 있는 TPS 플랫폼을 개발하였다. 이 결과는 향후 일반화될 TPS에 품질 개선을 위한 기반으로 활용될 것이며, 서비스 사업자 입장에서는 품질 기준을 수립하는데 기준으로 활용될 수 있으며, 신규 시스템 개발 시 개발 방향에 지침으로 활용될 수 있을 것이다.
