高速公路通信专网除需支持高速公路信息管理、沿线监控和联网收费等业务的实时传送,还是提高高速公路的运营效率、管理水平和安全保障能力的重要手段。其系统设计和设备选型除符合项目管理体制结构和业务需求特点外,还应结合目前专网技术发展,确保系统功能可靠、技术先进、易于管理维护。本文重点探讨了沪宁高速公路江苏段通信专网中以太网、OTN、PTN技术应用的技术背景、功能定位与组网方式,为其它高速公路通信专网建设提供有益的参考。
In addition to the need to support expressway information network management, highway monitoring and networking services such as real-time transmission of fees, or improve the expressway’s operational efficiency, management level and an important means of security capabilities. In addition to its system design and equipment selection in line with the characteristics of the project management system structure and business needs, but also with the current development of private network technology to ensure that the system features reliable, advanced technology and easy management and maintenance. This article focuses on the Shanghai-Nanjing Expressway Jiangsu communications network Ethernet, OTN, PTN technology application technology background, function positioning and networking, and other highway communications dedicated network construction provides a useful reference.
