Demand Background

Since 1988, the first expressway in China’s mainland Shanghai was opened to traffic since Jiading Expressway and the breakthrough of zero expressway in China’s mainland was achieved. Especially after 2000, the rapid development of expressway construction in China and the total mileage of expressway construction by the end of 2015 Achieving Highway 125373 has already surpassed the United States in ranking first in the world. 




Solution
ONV Optical Network is regarded as a complete network solution for the construction of highway electromechanical engineering. It mainly provides network solutions for application of monitoring systems and communication systems.
Monitoring System Network Solution
The monitoring system is to connect surveillance cameras deployed at highway sections, bridges, tunnels, etc. to the monitoring center through access networks. The access network is deployed by deploying industrial switches to form an ERPS ring network. As an ITU-TG standard ring network protocol, ERPS is implemented based on Ethernet, and can achieve fault protection capabilities of 20ms level to realize the interconnection and interoperability of the network and reliable transmission. Each access ring network is connected to the sub-center through the monitoring and aggregation switch at the convergence point of the road segment. The sub-center core switch and the provincial monitoring center are interconnected and interoperable. The monitoring system is controlled and available throughout the province. The PIM-SM protocol is deployed on network devices to optimize video traffic.
Program value
Switch ring technology ensures the reliable operation of the network. The entire line of optical network switch, whether it is industrial switches or general-purpose switches, support the networking technology based on the ERPS standard ring network, make full use of optical fiber resources to improve the utilization of bandwidth
The switch supports single-fiber ring network technology and saves fiber resources. The ONV full-line switch products can realize single-fiber ERPS protection rings, which can save optical fiber resources and reduce construction costs.
Provide a total solution. ONV Optical Network can provide industrial switches, general-purpose all-line switches and other products to meet the needs of the entire highway network of electromechanical engineering application of the overall network products
