Abstract:At present, China'scommunication technology hasachieved significantresults,andthe fifth generation mobile communication technology (5G) has tended to be perfect.Therefore,building a 5G transmission network has practical significance.The core advantage of Packet Transport Network (PTN) technology lies in its powerful statistical multiplexingcapability,whichcanmeet the transmisionneeds of 5G packet dataservices.Basedon this, this article studies the application of PTN technology in urban transport networks under 5G environment.

Keywords:PTN technology;5G transmission network;group transmission

随着城域传送网规模的持续扩大,高带宽、低时延和业务多样化已成为其典型标志,由此对传送网提出了新的要求:核心层网络需具备高带宽、大容量和高速转发能力,以确保网络的高效运行;汇聚层网络需支持灵活的路由转发,满足数据动态配置要求;接入层网络需提供丰富的接口和业务接入能力以满足不同用户的需求。(剩余3217字)
