The northern border is cold and icy. On the eve of the Spring Festival, officers and soldiers from a certain unit of the Information Support Force braved the extreme cold of minus 40 degrees Celsius and advanced into the forest and snowy plains to conduct practical training under harsh conditions. The intelligence feedback from the reconnaissance team is urgent, and the data rate of a certain type of equipment is abnormal... After the battle started, special situations followed one after another, and multiple fronts on the command post situation screen lit up "red lights" one after another. These new equipment are the 'nerve centers' that support system operations, and whether they can withstand the test of severe cold needs further verification. ”The commander of the department told reporters that they carried out practical training under extremely cold conditions in conjunction with the Spring Festival preparedness, in order to explore the technical performance of fresh equipment and hone the winning ability of combining personnel and equipment. Activate the mobile communication platform, synchronously open the launch relay equipment, and be ready to access the satellite at any time! ”Faced with strong interference from the enemy, Sergeant Li Deshuai quickly assessed and remotely pushed intelligent control instructions through the command system. After a few minutes, the signal indicator light turns from red to green, and the encrypted intelligence is steadily uploaded. At the same time, the core network of the director's department is congested due to a large amount of data loading. The network operation and maintenance team quickly retrieved the communication resource map of the training area, activated the multi-path support plan, configured multiple information nodes, and built an "elastic ring network". Before long, the bandwidth pressure on the director's department eased, and the main and backup links were fully connected. Nowadays, we are no longer bystanders in system operations, but 'data sentinels' embedded in the command chain. ”Li Deshuai introduced that in this training, their seats were placed in front of the combat command center, achieving full-time embedding and accompanying support, testing their ability to support global network information in extreme environments. The waveform of a certain section of border defense optical cable transmission is abnormal, and the attenuation of the fiber optic joint is approaching the threshold. The emergency repair team should immediately go forward to deal with it! ”With the commander's command, optical cable technician Zhao Zhenying quickly released the inspection drone. At the same time, Captain Zhao Fei led the team towards the target section. After more than 10 minutes, the drone transmitted real-time footage back to the vehicle terminal: the target area is located on a steep slope near the river, with deep snow and steep terrain. In the past, it took two hours to conduct a hiking survey, but now the on-site situation can be fully displayed on a square screen. ”Zhao Fei pointed to the screen of the car terminal and exclaimed at the changes brought about by technological empowerment. The car has reached a steep slope and cannot move forward. Officers and soldiers carry equipment and walk through the snow with one foot deep and one foot shallow. The piercing cold wind instantly penetrated through the cold mask, and the exhaled heat condensed into white frost on the eyelashes of the officers and soldiers. After finding the marker stone, everyone quickly took action, cleared the snow, chiseled open the frozen soil, and opened the box for testing - the on-site data was completely consistent with the platform warning. In low temperature environments, optical fibers are as brittle as ice, and welding relies entirely on manual effort. Zhao Feisuo took off his gloves and squatted into the snow pit to work with bare hands. The wind cut like a knife, and his hands were quickly numb from the cold. He took a breath of hot air to warm his hands and continued to focus on his homework. Soon, with the muscle memory formed by thousands of training sessions, he accurately completed the fiber optic fusion. Wherever the battlefield extends, the support of cyberspace must cover it. ”Zhao Fei introduced that he had been guarding the border for 16 years and witnessed the transformation of the army from "iron foot patrol" to "data flow protection". Although the means have changed, the mission remains unchanged - every command and every frame must arrive at the battlefield accurately, timely, and safely. Ice and snow strengthen the muscles and bones, and passion writes loyalty. On the victorious journey, the heroic song echoed through the forest and snowy plains: "We measure mountains and rivers with our youth, laugh proudly in the cold and frozen land, code forms a formation of electric waves like a rainbow, and the Northern Xinjiang Jiaolong network wins..." This song is a true portrayal of these new era "data sentinels" and their firm oath - to melt thousands of miles of ice and snow with their youthful passion, build a strong network information Great Wall with new combat power, and ensure that this "information lifeline" is always smooth.
