초록

통신 망의 진화에 따라 대용량 데이터 기반의 안정적인 고속 데이터 연결이 필요한 서비스들이 증가하고 있다. 사용자의 단말로부터 취합된 패킷 데이터의 용량이 증가하면서 코어 네트워크로 전달하는 중간 링크인 백홀 네트워크의 지연에 대한 품질진단의 중요성이 대두되었다. 본 논문에서는 응용서비스 품질에 영향을 미치는 RTT(Round Trip Time) 지연과 성능저하의 원인이 될 수 있는 회선 대역폭(Bandwidth) 및 스위치 내 속도 불일치, 구간별 버퍼(Buffer) 사이즈, 라우팅 정책 등 여러 인자의 진단을 통하여 백홀 네트워크에서 문제를 해결할 수 있는 기법에 관해 실제 사례를 통해 연구를 진행하였다.

With the evolution of communication networks, there is a growing demand for stable high-speed data connections to support services relying on large-capacity data. The increasing volume of packet data aggregated from user devices underscores the significance of quality diagnostics for the backhaul network, an intermediate link transmitting data to the core network. This paper conducts empirical research on techniques to diagnose issues within the backhaul network through practical case studies, through diagnosing various factors such as circuit bandwidth, speed disparities within switches, network segment-specific buffer sizes, routing policies, among other factors that could potentially cause RTT (Round Trip Time) delays and performance degradation.
