Abstract

In this paper, we have considered the network performance of the VoIP service with the measurement by an emulator, and analyzed the major factors to affect its performance. Also, we have used the measured values to investigate the traffic variations, where their values were observed in the commercial operated network after the delay, jitter and packet loss, and loss compensation methods were applied as the dominant elements. It is expected that our presented results will be a good data to provide the high-quality of voice service in the Internet.

본 논문에서는 VoIP 서비스를 사용하는데 있어서 IP 망에서 음성품질을 저해시키는 요소들을 Emulator를 통해 실험함으로써 음성품질에 영향을 미치는 요소에 대해 분석하였다. 그리고 QoS 분석에서는 실제 망 환경에서 겪을 수 있는 영향요소들에 대한 실측치를 반영하여 망 품질에 대한 망상태의 변화를 분석하였다. 망 품질의 가장 큰 영향을 주는 Delay, Jitter, 패킷손실에 대해 실측한 데이터는 IP망에서의 고품질의 VoIP 서비스를 제공하는 기반이 될 것으로 기대한다.
