Abstract

The NGN(Next-Generation Network) structure has been considered from various points of view as all If wireless-wired integration network and its performance is one of the main issue in these days. In this paper, various wired and wireless integrated networks with voice service are designed and simulated to obtain problems and factors affects the network performance using OPnet simulator. The characteristics only showed in the wired and wireless integrated networks are measured and analyzed compared with the single networks such as a wired or wireless networks. Especially, in the wired and wireless integrated networks showed degrading performance even if there are few transmissions in the network and furthermore, the various networks of increasing numbers of the nodes and transmission are simulated and evaluated.

NGN(Next-Generation Network)의 구조는 전 IP 유무선 통합망으로서 다양한 관점에서 연구되어져왔으며 이러한 네트워크의 성능은 가장 중요한 쟁점의 하나이다. 본 연구에서는 다양한 유무선 통합망에서 음성 서비스를 제공할 때에 발생할 수 있는 문제점과 요인들을 발견하기 위하여 OPnet 시뮬레이터를 활용하여 성능분석을 수행하였다. 단일의 유선망이나 무선망과는 달리 유무선 통합망에서만 보이는 특성을 측정하고 분석하였다. 특히, 유무선 통합망에서는 네트워크의 전송이 빈번하지 않은 환경에서도 전반적인 망의 성능이 저하되는 결과를 측정하였으며 그밖에도 노드수의 증가와 전송량의 변화에 따른 망의 성능을 비교 분석하였다.
