Application Analysis of PTN Transmission Equipment in Shuohuang Railway Company

随着铁路运输模式的不断发展以及科学技术的不断提高,铁路专有通信业务对承载网络的需求越来越高,以SDH为基础的传输模式,已经难以满足当前数据化、智能化的运营需求,PTN相较于现有的SDH传输来说,是针对分组业务流量的突发性和统计复用传送的要求而设计,以分组业务为核心并应用于多业务环境,大大提高了通信传输的效率和质量。本文主要围绕PTN设备在铁路通信网络中的应用进行了分析,以供参考。

With the continuous development of railway transportation modes and the continuous improvement of science and technology,the demand for railway proprietary communication services to carry networks is increasing.The transmission mode based on SDH is no longer able to meet the current needs of data-driven and intelligent operations.Compared with existing SDH transmission,PTN is designed to meet the requirements of sudden packet business traffic and statistical multiplexing transmission,focusing on grouping services and applying them in multi service environments greatly improves the efficiency and quality of communication transmission.This article mainly analyzes the application of PTN equipment in railway communication networks,for reference.
