"The optical cable channel of Xuangang Station is tested well, the IP address of the transmission device has been changed, and the database has been downloaded."

"Received by the network management center, the optical port docking can be carried out."

At 3:20 a.m. on January 17, the quiet of the winter night was shattered by a sonorous conversation on the phone. At this time, the network management center of the Taiyuan communication section of China Railway Taiyuan Bureau Group Co., Ltd. was brightly lit, and Director Li Min received the construction scheduling order issued, and after confirming that the site was ready, while emphasizing the safety precautions for construction operations to the operators, he shuttled between the rows of roaring black cabinets and data network management terminals in the communication network management machine room, and opened the network cutting and data test of the electronic ticket transmission equipment of xuangang station of the Beitong Pu Line.

At the end of the 4 hours of intense and busy night skylight work, everyone showed a smile, they are known as the "nerve center" of railway transportation "network administrators".

In the communication section of the Railway Bureau, they are "inspection and treatment doctors" who guard the smooth passage of railway transportation channels day and night, and although their work is not directly facing passengers, it is closely related to passengers buying tickets and traveling. In the places where passengers can't see, they monitor the data transmission status of 1325 hosts and 13959 devices and 4585 communication lines scattered around the world through 149 computers every day, deal with faults in a timely manner, and optimize the network in a timely manner.

This year marks Li Min's 8th year as the director of the Network Management Center. During the Spring Festival, the passenger flow increased significantly, the impact of passenger ticketing demand on the channel increased, the communication channel is equivalent to the blood vessel of the passenger ticketing system, once the channel congestion and failure, it will directly affect the ticket purchase speed. In order to ensure the smooth and convenient purchase of tickets by passengers, Li Min and his co-workers used 15 sunroof points from 00:30 to 4:30 a.m. to conduct real-time monitoring and dynamic network access optimization of 177 electronic ticket main backup channels in the bureau. A cup of coffee and a bag of crisp noodles are the standard for their night shifts, and this busyness begins a month before the Spring Festival.

Every two hours to 149 computers and backstage host equipment inspection, a day, a network administrator to walk more than 40,000 steps, but also to complete a month 30 full points of night skylight operation, such a working environment and work rhythm, they have become accustomed to. "The network management monitoring center is like a nerve center, in the event of a failure, we must do a good job of coordination and command and disposal at the first time, we will always stick to the place where the passengers can't see, and guard the passengers' smooth purchase of tickets and the safe operation of the train." Li Min said.

With the application of new technologies such as artificial intelligence and the Internet of Things in the railway field, the work of the network management center will become more and more important and busy, but in Li Min's view, as long as passengers travel more conveniently and comfortably, their work is worth it.
