In order to avoid the problem of long extraction time, Nanbayashi Guiichi has limited the length of the security monitoring record to only one hour. Pen % fun % Pavilion www.biquge.info

However, the extraction time still takes four hours.

Exactly four hours!

For such a long time, Nanlin Guiyi naturally couldn't accept it. Because, in four hours, there are too many variables, which may be discovered by the network security technicians of our store; It is also possible that the Kasai Police Station, the S organization planted a dark line, and the security monitoring records will be cleaned up.

"Sir, the computing power of the carrying equipment of the system is seriously insufficient, and it is impossible to unlock the upload speed limit of the network service provider, according to the network bandwidth calculation of the Kasai Police Station, the four-hour extraction time is already the best solution for the system." Butler explained.

A smile appeared at the corner of Nan Lin Guiyi's mouth, "This problem is simple, I'll solve it!" ”

Butler's carrying equipment is indeed seriously lacking in computing power, but Nanlin Guiyi also has a small number of enterprise-level server broilers, although it is not a supercomputer, but the computing power is also very powerful.

This kind of enterprise-level server broiler cannot be used as a carrier equipment for Butler. After all, a broiler is a broiler, the server is someone else's, and Butler can't have shifted the past.

But Nanlin Guiyi can temporarily call broilers, Nanlin Guiyi is a world-class hacker, he can temporarily call the broiler of the enterprise-level server, attack the network service provider, and modify the network bandwidth limit of the Kasai Police Station.

Nanbayashi Guiyi vigorously connected to two enterprise-level server broilers, and through them, entered the network service provider that provides broadband for the Kasai Police Station.

In less than a minute, Nanlin Guiyi unknowingly entered the background database of the network service provider and found that the network bandwidth of the Kasai Police Station was 100M.

However, the 100M broadband service is not equal to the same speed. Rather, it is a limit of 100M downlink and 10M uplink. To put it simply, when downloading, the fastest can reach 12.5MB/s, and when uploading, the fastest can only reach 1.25MB/s.

Similar cheating services, on a global scale, are basically the same, limiting the upload speed. If you want the same speed as the uplink and downlink, you also need to pay an additional fee.

If Nanbayashi wants to extract the security surveillance records of the Kasai Police Station, he needs to upload speed. The speed of the upload determines the length of time.

However, Nanlin Guiyi did not immediately modify the background data of the network service provider, but tested the security system status of the network service provider.

Once Nanlin Guiyi also modified the background data of the network service provider, he already had experience. If the bandwidth data is modified at will without proper security protection, the network service provider can find out in minutes.

In order to avoid such a tragic thing from happening, Nanlin Guiyi is testing the situation of the security system, he only needs to modify the network bandwidth of the Kasai Police Station for a short time, and it does not need to be permanently modified, which is not a troublesome thing.

After some probing, Nanlin Guiyi had figured out the security system of the network service provider, and he immediately tampered with the network bandwidth of the Kasai Police Station, but modified the uplink speed, from 10M uplink speed to 1000M speed.

That's right!

It is indeed a 1000 megabyte uplink speed, and you can upload up to 125MB of content per second!

The Kasai Police Station's network service is a fiber optic line that carries a speed of 1,000 megabytes, which is not a big problem. As for higher speeds, I'm afraid there's a problem!

Although, theoretically, there is no speed limit for fiber optic lines. However, in fact, the speed of optical fiber lines is limited depending on the manufacturing technology of optical fibers and the diameter of optical fiber lines.

Once the speed is too high, problems such as optical signal-to-noise ratio, nonlinear transmission and dispersion will affect the reliability of optical fibers. In addition, Nanbayashi Guiichi found that the computer equipment of the security monitoring system of the Kasai Police Station only supports gigabit networks at most.

To put it simply, it's the hardware that limits the software!

The computer equipment of the security monitoring system and the network card configured can only support a gigabit network, even if there is a 10,000 megabit bandwidth, it can only stare dryly.

After the uplink network bandwidth was adjusted, Nanbayashi Guiichi immediately instructed Butler to extract the security surveillance records of the Kasai Police Department. Since the uplink network bandwidth has increased by 100 times, the extraction speed has indeed increased by nearly 100 times.

What used to take four hours and 240 minutes to extract is now just under three minutes!

Such an increase in efficiency is simply an exaggeration.

Sure enough, more advanced technology has greatly improved work efficiency.

Nearly three minutes later, Butler reminded Minamibayashi that the Kasai Police Department's one-hour security surveillance record had been extracted.

Nanlin Guiyi ordered to extract more security monitoring records, anyway, the speed is fast enough now, and it doesn't hurt to extract more security records.

"Sir, what about the specific time node?" Butler inquired about Nanlin Guiyi and asked for more specific orders.

Nanlin Guiyi ordered again, "Extract the security monitoring records from the back to the front, and the security monitoring records within today, all of them are needed." ”

"It will take about 42 minutes, please wait." Butler was quick to give a reminder.

For more than half an hour, Nan Lin Guiyi naturally couldn't waste it, and he began to check the security monitoring records of the one hour that had been extracted.

However, just twenty minutes later, Butler gave a hint, "Sir, you can't continue to extract security surveillance records." ”

"Huh?" Nanlin Guiyi wondered, why can't he continue to extract security monitoring records?

"According to the system detection, the security monitoring system of the Kasai Police Station has been turned off, and the system can no longer be connected to the security monitoring system of the Kasai Police Station." Butler relieved Nanlin to be one.

"Humph!" Nan Lin Guiyi snorted coldly, his worries really became a reality, the security monitoring records of the Kasai Police Station, I'm afraid they have been cleaned up, right?

As for who cleaned it up?

It's definitely the inside line of the S organization at the Kasai Police Station!

"How many hours of security surveillance records have been extracted?" Nanlin Guiyi asked.

"From 17:23 p.m. to 9:56 a.m." Butler gave an accurate answer, and the security monitoring record of more than seven hours has almost covered the entire period of time when Imai Kazama was arrested.

Thankfully, Nanbayashi Guiichi revised the Kasai Police Station's network bandwidth data. Otherwise, an hour's worth of security monitoring records will not be exhausted!

"By the way, Butler, did the security surveillance system capture anyone who turned off the security surveillance system before the police station went offline?" Nanlin Guiyi asked.
