Transportation Industry solution

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.
