Usually, people using WeChat always complain about the poor network, every time they open it and turn in circles, sending files is very bad. But as a communication tool with a monthly activity of more than one billion people, WeChat has actually made great efforts behind the scenes in order to allow everyone to receive messages in a timely manner.
Today, through the WeChat Pie public website, WeChat officials have introduced the story of the 0.1 seconds after pressing the send message button.
Taking Xiao Wang’s confession to Xiao Mei as an example, about 0.1 seconds after he pressed the send button, Xiao Mei’s WeChat popped up with four words: I like you.
But in fact, this 0.1 second had to go through multiple relays before it finally reached Xiaomi’s WeChat, which is somewhat similar to a courier delivering a delivery.
First, the “I like you” message is encrypted by Xiao Wang’s WeChat and put into a confidential envelope. With a whoosh, the confidential envelope was sent to the WeChat server’s delivery room.
The No.1 guy working in the communication room has a lot of responsibility because from here onwards it is the WeChat intranet. He has to keep in touch with all WeChat users while preventing undesirable people from entering the intranet.
Only after confirming that the confidential envelopes are of proper origin does he hand them over to the No. 2 boy.
And Little Brother No. 2 will first do some necessary checks, such as.
- are Xiao Wang and Xiao Mei close friends?
- has Xiao Mei blacked out Xiao Wang?
If all are okay, he will put the confidential envelope into Xiao Mei’s exclusive delivery cabinet and lock it up.
Then, the second boy told the conveyance room: Xiao Mei’s envelope was put away.
As soon as the conveying room heard this, it immediately gave Xiaomi a WeChat shout: you have a new courier, come and get it.
If Xiaomei did not look at WeChat at this time, the confidential envelope would be temporarily placed in the courier cabinet.
If Xiaomei opened WeChat, her WeChat would immediately run to the conveying room and say: I want to pick up the courier.
The first little brother will immediately notify the second little brother and the second little brother fire Xiao Mei’s exclusive courier cabinet. Empty the courier cabinet and take out the confidential envelope to the conveying room, which then forwards it to Xiaomi’s WeChat.
Waiting for the confidential envelope to pass back to the phone, after the phone local decryption, the envelope finally opened, Xiaomei finally saw the four words sent by Xiao Wang.
But the latest number of monthly active accounts for WeChat and WeChat has reached 1,299.1 million, and there are probably tens of millions of people who pressed the WeChat send button at the same time as Xiao Wang.
The messages they send are not only text but also emoticons, voices, pictures, videos, and links. There are single chats as well as various group chats, large and small. What served Xiao Wang could never be a few simple servers, but a mega-message system that is rare in the world.
In order to help the 1,299.1 million Xiaowang Xiaomei keep in touch with each other, this system carries hundreds of billions of trillions of messages every day, day and night, never stopping.
Behind every stable and reliable 0.1 seconds, there is the wisdom and sweat of WeChat engineers.
