After the lifting platform was raised to level with the stage, Chen Minhao took a step forward and walked to the middle of the stage.

The dazzling lights on the stage suddenly turned on, and the gorgeous stage built with heavy money appeared in front of the audience. No matter which angle you look at, the entire stage is lit up.

The two rectangles around and on both sides of the hexagonal truss are surrounded by light, and the aesthetic harmony between the lighting and the large screen makes it feel comfortable and natural.

Many viewers in the audience let out an exclamation of "wow", which was so shocking!

With a smile on his face, Chen Minhao said: "Thank you to the audience who came to the scene, and thank you to the audience who participated in this concert through the Internet." ”

The audience, which was already boiling, immediately erupted into an earth-shaking shout.

?“ Chen Minhao!""Chen Minhao!""Chen Minhao!"

The shouts were uniform, and louder and louder, and huge waves of sound converged and flooded the entire sports center.

On the penguin video, the barrage has exploded.

Judging from the dense barrage, the audience who was watching the live broadcast at this time must have reached millions.

"From this stage, I seem to see the funds burning!"

"It's finally started~"

"Chen Minhao, I love you!"

"Although I am at home, my heart has flown to the Pengchengwan Sports Center. ”

.......

On the barrage, some people were excited, some were happy, some were paddling, and some were scolding.

....

Penguin Riverside Tower, 13th floor. The location of the Penguin Video operations staff.

Li Weijie walked through the busy staff and found his assistant Lu Yaxian.

"Xiao Lu, how many people are watching the live broadcast now?"

"Now there are 9.84 million, and that number is still rising. ”

Lu Yaxian said excitedly.

She knew what the number was questioning.

Previously, it was estimated that the upper limit of the number of people watching the live broadcast of the concert was 10 million, but now the concert has reached this number at the beginning.

This means that after the concert is over, the number of viewers who are online at the same time will definitely break the estimated upper limit.

And this will definitely break the record of all previous live concerts, and may even break the record of the number of people watching live broadcasts online on online platforms.

Hearing the exciting news, Li Weijie's face changed greatly, and he thought farther than Lu Yaxian.

Compared with live TV, the audience has higher requirements for viewing experience.

However, compared with the coaxial cable transmission of TV signals, there are many uncertainties in the transmission of the Internet.

Signal stability, production speed, cross-regional transmission efficiency, and disaster recovery system are all crucial.

In the face of Chen Minhao's concert, a large-scale live broadcast event with unprecedented traffic, Penguin's CDN team (content delivery network, a direction of technology) has made a lot of preparations to ensure the smooth guarantee needs of users' rich interactions such as ultra-high-definition image quality.

What to do if the signal source fails during live broadcasting, what to do if the operator's network fails, and other accidents, the CDN team imagines various possible problems and makes a thorough plan.

Or rather, they made what they thought was a well-planned plan.

Penguin Riverfront Tower, 15th floor. The office of the R&D personnel of the Penguin Video CDN team.

The programmers stared dumbfounded at the data in the monitoring system.

They envisioned all sorts of possibilities, but they didn't expect so many people to just start watching online.

"Chen Minhao is so good, now that the concert has just begun, there are more than 10 million viewers watching it online. ”

The number is still growing wildly, what are these idiots in the operations department doing? The upper limit of the estimate was 10 million, and now it has exceeded 10 million at the beginning. The system really can't bear it!"

"Brother Lu, do you remember that a few days ago you complained about Brother Shen's fuss, saying how could it reach the estimated upper limit of 10 million. A non-verbal intern spoke.

The office was suddenly filled with a cheerful air.

The jelly was short-lived, and several R&D members of the CDN team conducted alarms almost simultaneously.

"Boss, the network of network line 3 is overloaded. ”

"Boss, the backup B line is also currently experiencing network overload. ”

"Boss, some users have experienced delays, delays of more than 5 seconds. ”

"Boss, the network is occupied, and some users have different frequencies of audio and video. ”

was called the boss by everyone, the bald young man, his name was Shen Jiaming.

He said calmly: "Start the first set of emergency measures to guide users to abandon the ultra-clear mode and switch to the normal clear mode." ”

The phone rang suddenly, and Shen Jiaming, who was frowning, subconsciously wanted to hang up, but when he saw that the caller ID was Li Weijie, he still chose to pick it up.

Li Weijie's impatient voice immediately came from the earpiece: "Old Shen, there is nothing wrong with your system, right?"

Shen Jiaming said: "There is no absolutely reliable system, and local failures are the norm. ”

"What do you mean, it's already broken?" Li Weijie's voice suddenly soared.

Shen Jiaming felt that it was really tiring to communicate with people who didn't understand technology, and patiently explained: "Although there are abnormalities in the system, we can ensure that there are no abnormalities in the core business through some methods to protect and protect them." ”

Li Weijie breathed a sigh of relief, and his heart fell into his stomach: "In other words, there won't be a problem with tonight's live broadcast, right?" ”

Shen Jiaming ruthlessly punctured Li Weijie's expectations: "Of course not, there is an upper limit to the bottom plan." ”

, ruthless.

"What's the upper limit?" asked Li Weijie anxiously.

"Twelve million, that's the upper limit of our past redundant drills. This number is for reference, and the maximum number of people who can watch the concert at the same time is 10 million. ”

"What will happen if we exceed this upper limit?" Li Weijie was very worried and regretful in his heart, why did we estimate the upper limit of 10 million at that time?

Shen Jiaming said: "I will give an inappropriate example, that is, the drill was preparing for a magnitude 7 earthquake, but now there is an 8 magnitude earthquake. ”

"So what now?" asked Li Weijie while holding the phone, running towards the safe passage to the 15th floor.

If there is a serious lag in the picture during tonight's live broadcast, the penguin video will definitely be sprayed to death.

And within the company, you have to carry a part of the pot.

But you really can't blame yourself! Who would have thought that there would be so many people watching the live broadcast of Chen Minhao's concert!

Li Weijie ran to the 15th floor and found the area where the CDN team was located.

Shen Jiaming saw Li Weijie and said directly: "At present, there are more than 12 million viewers watching online. ”

Li Weijie said: "Don't go wrong, do you have any solution now?"

Shen Jiaming sighed: "I have now diverted from the line, which will encroach on the bandwidth resources of other content and affect the experience of other users who do not watch Chen Minhao's concert." Hey, I've already done this project, and this year's performance will be good, but now it looks cool. ”

Li Weijie said: "This is indeed not enough that we expected before, let's carry this together." Next, it depends on how many people can rush to watch it online. ”

"Don't go over fifteen million. Shen Jiaming said.

Li Weijie asked: "Even if it exceeds 15 million, will there be problems again?"

Shen Jiaming nodded.

Li Weijie's mood at this time was very contradictory, others were worried that their boyfriend would not come, and they were also worried that their boyfriend would come randomly, while he was worried that the number of online viewers would not rise, but he was also worried that the number of online viewers would rise.

........

Dressed in white half-sleeves and blue jeans, holding his guitar, Chen Minhao stood in the middle of the stage, pausing to get himself used to the lighting and atmosphere of the stage.

He said: "The city under our feet, Pengcheng, as the southern gate of China, relies on the geographical advantages of Hong Kong and Macao, and the economy has undergone earth-shaking changes in recent years. Since the reform and opening up, Pengcheng has attracted countless aspiring young men and women from all over the country to come to work hard, this group of young people, for Pengcheng dedicated the best ten years of their lives, in Pengcheng, they taste the ups and downs of beautiful youth, love, career, friendship ......"
