Introduction

It is said that the four Tang monks and disciples traveled westward to learn scriptures, and finally came to the western world of bliss to obtain the true scriptures, but how to bring back the true scriptures became a big problem, and the story unfolded:

In the 81 year of Zhenguan of the Tang Dynasty, one morning

"Wukong, as a teacher, I led you to finally obtain the True Sutra, but how can you bring the Sutra back to Datang?"

"Master, don't worry. My grandson has developed the TCP Agreement on the basis of somersault cloud. As long as you strictly study my magic formula and strictly abide by my custom rules, as long as you constantly put scriptures on the somersault cloud, somersault cloud will automatically transport the Sutra back and forth, and I can guarantee it back to Datang!"

"it's really Wukong. In that case, Wuneng, I'll leave the matter to you as a teacher. It seems that the teacher will have to ask the Buddha for more scriptures."

Dasheng, Bajie, Sha Wujing and his party came to the "Daleiyin Temple 224 Warehouse" to prepare to transport the True Sutra. The Great Sage asked Bajie, "nerd, I taught you the magic formula of 'TCP Agreement' last night. Can you learn this spell?"

Bajie looked ashamed: "the formula of this spell is too long and the principle is too complicated, so I didn't learn to hum."

Big Sheng smiled, "you stupid pig, although you were Marshal Tianpeng, you still have to study the latest spells carefully."

Bajie said curiously, "I'd like to hear more about it."

Wukong stood up lazily and said, "if you want to really learn the TCP Agreement spell, first tell me where our scriptures are going to be transported."

Bajie hurriedly took out the address written by the master and said, "to be transported from the 224 warehouse of Dalei Temple to Datang Wangcheng."

"there were many doors in the Tang Dynasty. Which door does Zhenjing want to enter?" Wukong then asked.

"as the master said yesterday, send it to Gate 80."

The Great Sage said, "well, the nerd still has a good memory. Let's go to the front."

In front of the 224 warehouse of the Great Lei Yin Temple is a Buddhist square. Usually some believers come to recite the scriptures, but now there are only three Wukong brothers.

"wait a minute, I'll first establish a connection for the guard of Gate 80 in Datang King City," the Great Sage said, reciting the formula, and a cloud appeared out of thin air.

The Great Sage wrote a letter on the cloud by reciting the formula:

"Guard, I'm the Great Sage. I'm in the warehouse 224 of Da Lei Yin Temple. I want to establish a connection with you. My serial number is 1024. Please come in!"

The somersault cloud is inscribed:

Fayundi: 224 warehouse of Da Leiyin Temple in Xitu

Cloud Collection: Datang Wangcheng, Gate 80

The great saint read a formula, and the somersault cloud floated to the east quickly.

An hour later, the somersault cloud came back, and it said:

"Great Sage, I have received your letter. There is a serial number 1024 in your letter. Is it correct? agree to establish our connection. My serial number is 2048."

Bajie hesitated and said, "is the connection established like this? is the TCP spell so easy?"

The Great Sage patted Bajie on the head and said lazily, "nerd, this is only the first step. If you want to establish a connection, you need to send them another letter."

"Guard, I have received your confirmation letter, and I see that your serial number is 2048. I have begun to transport the Sutra."

Bajie thought to himself, "is this the connection? why don't I see your somersault cloud connecting Datang and Dalei Temple?"

Big brother, why did you use somersault cloud to send three letters? Sha Wujing also helped.

"this is the essence of my magic-the three-way handshake." my grandson analyzed it for you. "the main purpose of these three-way handshakes is to verify that there is no problem with the ability to send and receive letters on my side and the guard side of Datang. This proves that the connection is open, and then you can formally send scriptures."

The first handshake: big Leiyin Temple sent a letter, Wangcheng received, at this time Wangcheng will understand-Great Leiyin Temple letter sending ability and their own ability to receive letters is no problem

The second handshake: Wang Cheng sent a letter, and the Great Lei Yin Temple received it. At this time, the Da Lei Yin Temple will understand that the sending and receiving of the letter from the Great Lei Yin Temple are all good, and at the same time, there is no problem with sending and receiving letters from the King City. Otherwise, you won't get a reply from the somersault cloud from Wangcheng, but Wangcheng still doesn't know what its mail function is. So you need a third handshake.

The third handshake: the Great Leiyin Temple sent a letter again, and Wangcheng received it. At this time, the Great Leiyin Temple has confirmed that it is no problem to receive and send letters.

The purpose of this response is only to allay the concerns of the royal guards about their letter-sending function and the mail-receiving function of the Great Lei Yin Temple.

Bajie then asked, "Big Brother, you have worked so hard to establish a connection, why not use somersault cloud to transport scriptures yourself?"

The Great Sage said: "in order to make me feel at ease and learn from the scriptures, Buddha made restrictions on my somersault cloud. I couldn't fly back to Datang with somersault cloud, so I created my own 'TCP Agreement' spell to let my somersault cloud deliver goods by myself. even if the somersault cloud disappears on the way, I can use my mana to re-produce a new somersault cloud."

"then how do these somersault clouds know how to send the sutra to Datang Wangcheng?"

"Don't worry, my grandson's somersault cloud has my spirituality, and I have my monkey grandson mark it at different forks in heaven. The monkey grandson at each marked point will see the letter on my somersault cloud, and they know the way. They will put my somersault cloud on a new and correct heavenly path, continue to float to the destination, and eventually reach Datang Wangcheng. My monkey grandchildren are very intelligent, and they have given themselves a stage name 'Router'. "

"by the way, there are so many scriptures that you have to break them into a small package."

"number each package," said the Great Sage. "in this way, when you get to Datang, the guards can safely put them in numbering order."

"what if Brother Monkey, your somersault cloud doesn't have enough power on the way and drifts away? isn't that book lost?"

"the somersault cloud drifted away on the road, so just copy another scripture and send another to Datang. In this case, we have no choice but to resend that package."

The Great Saint silently read the formula, divided the scriptures into 10 parcels and arranged them in a row according to the number.

"my mana can only support three somersault clouds, so I can only send up to three parcels at a time, according to the serial number, and the first one is 1 Magi 2 Magi 3 parcels." Dasheng said that the use of magic generated three somersault clouds, loaded with scriptures, and somersault clouds drifted away toward Datang.

The Great Sage continued, "according to the speed of my old grandson, if after three hours, Datang has not confirmed it to us, it will be lost and can only be reissued."

Three hours later, when Bajie was drowsy, the somersault cloud finally came back, and it was written on the cloud: package 1 has been received.

"it seems that my old Sun's spell is still quite effective," said the Great Sage. "Datang confirmed that he had received the first package of the scriptures, and we can send another one." he said the spell and sent out the fourth package.

Bajie did not answer this time, thinking to himself: "finally have some understanding of the 'TCP Agreement' spell, the big brother is that as long as each time to ensure that there are three scripture packages sent out, and confirm that there is no loss can continue to send."

After a while, three somersault clouds floated over, bringing confirmation of the package of Scripture No. 2 and No. 3.

"Brother Master, you are too good. If you don't lose the package, won't you soon finish transporting the scriptures, and then my old pig can go back to Gaolaozhuang early to marry Gao?" Bajie was admired by one side.

When the Great Sage saw that Bajie was being a nymphomaniac again, he didn't bother to pay any attention to him, and used somersault clouds to send out the 5th, 6th and 7th.

However, after waiting for a long time, the confirmation of package 5 did not come. Three hours later, the Great Holy way said, "it seems that the somersault cloud of package No. 5 has drifted away on the road, and the package of scriptures has been lost, nerd. Go to the warehouse of Dalei Temple and copy another copy, which must be exactly the same as the contents of the previous package No. 5!"

"what about parcels 6 and 7? did Datang get it?"

"I don't know yet. If they receive it, they will save it first, and if they don't receive it, they will have to resend it like package 5."

At this time, Wu Jing asked, "Big Brother, why do you send out three packages together? can't you send one for confirmation?"

"in order to improve the efficiency of sending packages, I use the sliding Cloud Protocol (sliding window Protocol) in my spell. if I send one to confirm one, but this is too slow, and my grandson can't do this all the time. I'll set N to 3, so I can send the text package and confirm it at the same time, so it can be faster."

Bajie can only go to the Great Lei Yin Temple to copy the scripture of package No. 5 again and let the Great Sage send it again.

After three hours, the somersault cloud of package 7 floated back!

The Great Sage said: "it seems that my somersault cloud is still good. Datang said that he had received the No. 7 package, which means he also received it on the 5th and 6th. Otherwise, they wouldn't have sent a confirmation cloud on the 7th."

Then the Great Sage sent a package No. 10, No. 9, and finally received a confirmation cloud from the guards of Datang.

The Great Sage sent Monkey Sun to Datang to confirm that the guard had received the No. 5 package, but the somersault cloud confirmed that it was scattered on the way, and the Great Sage did not receive the confirmation package, so he sent a new one.

So Bajie hurried to the master to ask for credit, saying that the Great Sage's "TCP Agreement" spell delivered scriptures.

The master smiled and shook his head, "Wukong, this is to ensure the unreliability of somersault cloud transportation and establish a relatively reliable way to send scripture books, but if the somersault cloud drifts on the road and leads to the loss of scripture parcels, you must also ask Wujing to re-copy scriptures and resend this scripture package. Although this' TCP agreement 'looks relatively safe and reliable, it is still slightly inadequate."

PS:TCP/IP protocol

The abbreviation of Transmission Control Protocol/Internet Protocol, also known as Transmission Control Protocol / Internet Protocol, also known as Network Communication Protocol, is not only the most basic protocol of Internet, but also the basis of Internet Internet.

TCP/IP defines standards for how electronic devices connect to the Internet and how data is transferred between them.

The protocol adopts a four-layer hierarchical structure, and each layer calls the protocol provided by its next layer to complete its own requirements.

In popular terms: TCP is responsible for finding problems with the transmission, sending signals whenever there is a problem, asking for retransmission until all data is safely and correctly transmitted to the destination. IP assigns an address to every connected device on the Internet.
