The success rate of 100% ticket grabbing is incredible for the experts and representatives present. If so, many people will use the ticket grabbing software?

Is there a vulnerability in 12306's website system? Or is Huizhong technology really so awesome? The ticket grabbing software written in half a day can have a 100% success rate, which is really slapping the face of the Ministry of Railways!

In the surprise of the crowd, Li Wenbin explained:

"According to the research of our technical team, the current ticket grabbing mechanism of 12306 is to issue tickets in the order of submitting orders, following the principle of first come, first served.

But in fact, no matter how fast the hand speed of our ordinary users is, it is impossible to be faster than the computer. Maybe you just chose to enter the departure and destination, and the order of the ticket grabbing software has been submitted.

The consequence of this is that all tickets will be robbed by the ticket grabbing software first, and the remaining tickets can be bought on the 12306 website, which has caused a consequence. No matter how early and punctual the user opens the 12306 official website, it is impossible for him to buy tickets when there are a lot of people grabbing tickets such as some popular trains or the National Spring Festival transportation. "

Li Wenbin's explanation made the experts present nod frequently, but some experts put forward different views:

"The purpose of 12306 website is to make it convenient for everyone to buy train tickets online. If the ticket grabbing software can help users in need to buy tickets, it has actually achieved the purpose of facilitating users. From this point of view, the emergence of ticket grabbing software is not a serious problem, but can stimulate the establishment of some ticket grabbing software companies and improve employment !”

After hearing this, Li Wenbin looked at the expert strangely. He must not be a technical expert. Before Li Wenbin explained, another expert sitting opposite the expert said:

"This is not the problem of no employment, but the problem of server carrying. Just now, representative Li mentioned that the speed of computers is much faster than that of ordinary people, which means that the ticket purchase process that might have taken three minutes should be completed in half a minute or even a few seconds. In this way, the whole server system will bear great pressure.

Moreover, representative Li, if I guessed right, you must have used a very frequent polling request mechanism in your ticket grabbing software system? "

Li Wenbin nodded to the expert with a smile and said, "yes, recursion according to time. The closer it is to the opening time, the shorter the interval. For example, when the train is opened at 8:00, 10:00 and 12:00, the polling request interval of the server is 50ms, that is, once every 0.05 seconds!"

"Hiss!"

The experts in the audience took a breath, once every 0.05 seconds, that is to say, a single order needs to request the 12306 server 20 times in one second. If 100000 people use this ticket grabbing software, it is 2 million requests in one second. Only a few large Internet companies in bath may encounter such a request frequency in China.

Moreover, close to the national day, Spring Festival and other special holidays, the number of tickets sold every day in 12306 is more than millions or even tens of millions, and most people will choose to grab tickets when the tickets are just on sale, which also causes the peak traffic of 12306 website to be extremely terrible!

Li Wenbin continued: "I believe that with the first come, first served principle of 12306, a lot of ticket grabbing software will emerge. If the success rate of these software is very high, it will attract more ordinary users to use the ticket grabbing software, which will cause a vicious circle.

Ticket grabbing software can generate profits by charging service fees from users. It may even be a scalper and a second dealer. It grabs tickets for some popular trains to its own website first, and then sells them to users at a high price. The 12306 server should not only bear the increasingly terrible traffic peak, but also bear the blame of users who really go to the 12306 website to buy tickets but can't grab tickets! "

"I think we can technically block the requests of these ticket grabbing software!" an expert said what most experts present said at the moment.

"No!" as soon as the expert had finished, a decisive voice of opposition resounded through the audience.

People's eyes followed the reputation, and the speaker turned out to be a leader of the Ministry of railways. The leader said with a serious expression: "12306 has a direct cooperative relationship with many domestic tourism websites. We can't block the requests of these websites because of this matter."

When the leader finished speaking, Li Wenbin also added: "in fact, according to our current research, these tourism websites and some Internet companies are most likely to launch these ticket grabbing services.

Of course, I personally believe that these companies should be banned from making ticket grabbing software or launching ticket grabbing services by administrative means, and only the booking needs within a reasonable range should be retained. However, the technical difficulty of ticket grabbing software is not complex. Even if we block the existing ticket grabbing software, new ticket grabbing software will appear, which can not solve the fundamental problem.

Just now, director Wang also mentioned that the mobile version of 12306 is also planned to be launched next year. At that time, the request volume of the whole website will double. That is to say, the more you go back, the higher the peak traffic of 12306. However, in normal times, the visit volume of 12306 may be hundreds or even thousands of times different from the peak, which leads to a great waste of server resources, so from the perspective of operation cost In consideration, like Dr. Wang Jian, I agree that 12306 should adopt cloud server to expand or reduce server resource allocation for different periods.

Next, I want to introduce to you the cloud server solution launched by Huizhong cloud specifically for 12306. With this solution, 12306 does not have to worry about any shortage or waste of server resources. All upgrades or downgrades are completed automatically in the cloud, which greatly reduces the cost and will not affect the normal business.

Including last year's wechat under Huizhong, which distributed red envelopes during the Spring Festival, also used this set of solutions as technical support! "

When Li Wenbin patiently explained the scheme in front of the projection screen, most experts and leaders of the Ministry of Railways present have fully agreed with the solution. You know, tens of millions or even hundreds of millions of people robbed red envelopes on wechat at the same time just on the night of new year's Eve last year. In contrast, this peak of 12306 is nothing!

More than two hours later, the experts and leaders of the Ministry of Railways in the whole conference room basically had a preliminary choice. Most experts and leaders believed that the final scheme adopted by 12306 should choose one from the schemes of Alibaba and Huizhong.

In terms of companies and technical strength, the two companies have their own advantages, and it is difficult for the experts present and the leaders of the Ministry of Railways to reach a consensus.

After whispering a few words, the person in charge of the Ministry of Railways and several leaders and leading experts who presided over the meeting looked up and said: "we believe that Alibaba and Huizhong are extremely excellent and excellent in terms of technical strength, and are competent to improve 12306.

However, although the website construction of 12306 is a livelihood project, it also costs the money of the state and taxpayers. Therefore, we have decided to give priority to and choose the company with lower cost and quotation between your two companies! "

"Coming!" Wang Jian's palm was sweating, but Li Wenbin looked relaxed!

The assistant sitting next to Wang Jian carefully stood up and handed the prepared quotation to the person in charge, as did Li Wenbin.

The eyes of the whole audience were focused on the person in charge of the Ministry of Railways who had two quotations in his hand. Although neither side made an offer in the open like an ordinary bidding meeting, no one dared to say anything. Do you dare to suspect insider trading?

Moreover, according to the regulations, the Ministry of Railways will certainly announce the bidding results after the meeting. Whether it is the quotation of Alibaba or Huizhong, you can know it clearly at that time!

They only saw that when the person in charge opened the second quotation on behalf of Huizhong, he frowned slightly. Then he looked up at Li Wenbin and handed the two quotations to other leaders of the Ministry of railways.

When some enterprise representatives on the field were thinking, the person in charge said, "Huizhong company will win this bidding!"

The eyes of the audience focused on Li Wenbin. Some representatives of enterprises that failed in the bidding also verbally congratulated him and Huizhong. At this time, Wang Jian, the representative of Alibaba, turned pale. He didn't understand that their team made an offer at the cost of tens of millions of losses after detailed investigation and study of the approximate costs of several potential competitors such as Huizhong, Why lose?

Li Wenbin, who is receiving congratulations from the crowd, inadvertently sweeps Wang Jian's eyes and can only say sorry. He knows that Huizhong will win in the end no matter what quotation Alibaba cloud gives, because on Huizhong's quotation list, only one sentence is written: "10 million lower than other people's quotations!"

Li Wenbin still remembers what boss Fang said to himself that day: "one of our purposes is not to give competitors any chance to turn over. Although we can win at a low price of 1 million, we always have to show our sincerity, just 10 million lower!"
