Abstract

In this paper, We have design and implement the network synchronization module for NG-SDH system having 120 Gbps capacity. and also evaluate the performance of it. We also propose analyzing algorithm clock characterisrics on NG-SDH node clock based on the evaluation results.

본 논문에서는 120 Gb/s급 NG-SDH 시스템을 위한 망동기장치를 설계 및 구현한다. 그리고 이를 바탕으로 동기클럭 모델링을 통하며 망을 구성하고 있는 NG-SDH 노드클릭의 클럭 특성과 최대노드 수를 도출하는 방법을 제시한다.
