Abstract

Currently digital TRS is providing the voice-oriented service based on stat-tree topology of 2.5G. As result of that, it has alimitation to accept the wide band multimedia services. Therefore, this paper designed the mesh topology based on packet networkand proposed the algorism of dynamic path establishment based on priority. In korea case, we confirmed that hop numbers priority base is more reasonable than distance priority base. And counted the trunk traffic including redundancy traffic to prevent the bottlenect situation and trouble. Also analysed the bandwidth between network management centers of backbone and access.

현재 디지털 TRS는 2.5세대 스타-트리 토폴로지 기반에서 음성중심 서비스를 제공하고 있어 광대역 멀티미디어 서비스를 수용하기에는 한계가 있다. 따라서 본 논문에서는 패킷망 기반의 메쉬 토폴로지를 설계하고 우선순위 기반 동적 경로설정 알고리즘을 제안하여 우리나라 실정에는 홉수 우선순위기반이 거리 우선순위기반보다 합리적임을 확인하였다. 또한 백본 및 엑세스 망관리센터간의 대역폭을 분석한 뒤 장애와 병목현상을 완화하기 위한 여유용량을 포함하여 트렁크 용량을 산출 하였다.
