Chapter 1018 is already done, you don't have to think about it anymore
The OSI seven-layer model is suitable for teaching, and theoretically explains the structure of the network quite clearly. However, in practice, it is almost impossible to find a network structure that completely conforms to the seven layers.
Because this thing is too idealistic and divided too finely. Theory has its own requirements, and application has its own reality.
And no matter how many levels it is, let alone the other comrades present, even the comrades from the Military Communications Institute cannot understand this stuff in this meeting. They have to sit down and study it seriously, and it takes a long process to master it.
Although Gao Zhendong's suggestion to divide the network into two parts sounded a bit lazy at first, and he still applied the division of the command system, other comrades felt that things were much clearer than what the military communication said at the beginning, at least it was not the feeling of a tiger trying to eat the sky and not knowing where to start.
"Well, Comrade Zhendong's suggestion is very good. We still need to do it like he did, with a top-level design from top to bottom and gradually subdivided. Otherwise, we can't even distinguish the research and development tasks, what to do at each stage, and which unit should do which part. It's simply incomprehensible." The leader of the Defense Work Committee said with a smile.
He likes to call Gao Zhendong to meetings, not necessarily because he wants Gao Zhendong to come up with some technology to solve practical problems every time, but more often like the current situation.
Gao Zhendong has an amazing ability to organize the logic and context of things very clearly, and to divide a complex matter into a relatively reasonable structure. He is also very forward-looking and has a clear idea in his mind about what to grasp and what to let go.
And he may not necessarily come up with any technology, but he can most likely provide a very useful idea or route. This route must be as closely matched to the goal of the matter and the current environmental capabilities as possible, and must be highly operational.
The last point is extremely valuable. Other comrades may have many ideas, but not many people can grasp feasible ideas.
In this way, something that was originally very complicated and had no direction could be done in a more reliable way after Gao Zhendong thought about it.
"Then how do you think the transmission part of this communication network should be built?"
Gao Zhendong burst into laughter before he spoke. His comrades didn't know what he was laughing at. This was not the kind of laughter that was performed during a speech to ease or set the mood, or to express an attitude. Instead, it was as if he had really thought of something funny.
However, extraordinary people must have extraordinary qualities, and comrades don’t care too much about this. Just laugh, laugh as much as you want, as long as there is goods, it will be easy.
Gao Zhendong's next sentence made everyone immediately know what he was laughing at.
"This transmission network also needs to be built in several parts. Today's topic is already very big and cannot be explained in a few words. If we simply divide it, the transmission network has at least two levels, or even more..."
It turned out that what he was laughing at was that he had divided the construction or planning content again.
"Which two floors?" The comrades from the Military Communications Institute didn't care how big of a deal this was and they refused to give up.
"Backbone network and regional network. The backbone network is actually the interconnection between various important nodes across the country, which requires high reliability, high bandwidth, and high availability. Regarding the backbone network, I suggest you communicate more with the Postal and Communications Commission. They have experience in this area. You can call me when the time comes, and maybe I can give you some advice."
It is hard to say how much experience the Postal and Communications Commission has in modern network topology these days. After all, it has just started out in an environment where manual switches are everywhere. Gao Zhendong feels that he has to get involved in this matter himself. Whether it is military or civilian networks, he can give them good suggestions.
Regarding Gao Zhendong's self-recommendation, no one thought that he was flattering himself. They all felt that it was needless to say that he had to be called, otherwise the comrades from the Postal and Communications Commission might themselves feel that it was inappropriate. After all, they knew where their most advanced equipment - the programmable switching system - came from.
"Well, let's organize the comrades of the Post and Communications Commission to discuss the backbone network construction with Comrade Zhendong." The comrades in the army agreed with Gao Zhendong's suggestion. The Post and Communications Commission was at least more experienced than us in large-scale communications. With Comrade Gao Zhendong's supervision, the result should be correct and the best result that can be obtained under the current domestic technical conditions.
"As for the regional network, this is something you have to put a lot of effort into. This area can be large or small. The smallest one may be on a battlefield, and the largest one may be within the scope of a campaign. Unlike the backbone network, this regional network has a complex, flexible, and changeable organizational structure, with different channel types, and may involve wired and wireless hybrid networking. It is very challenging to pay attention to details. My suggestion is to start from small to large, starting from the battlefield scope, and then work backwards to a higher level. Otherwise, it will be very difficult to handle everything at once..."
Gao Zhendong spent a lot of time slowly explaining some conceptual issues in this area to his comrades, but more importantly, in-depth communication was only possible by going into the details.
Having said that, at least the comrades have roughly figured out the problems they are going to face and can at least get started with the work.
"What if, I mean what if, we have a basic, usable transmission network, how can we make the data run on it according to our ideas? The complexity of this network, even the simplest one, cannot be solved by our previous methods." asked a comrade from the Military Communications Institute.
They have now learned to put aside unresolved issues and create a hypothetical environment for discussion.
All comrades were very interested in their problems.
Judging from Gao Zhendong’s description just now, the complexity of this thing is unimaginable. It is extremely difficult to run data in it. They simply cannot think of any method or technology to solve this problem.
In fact, this is because they have not yet learned the network model. If they have learned it, they will know that this is what Gao Zhendong just mentioned, the other half of the network - what the switching network needs to do.
Gao Zhendong's next words shocked all the comrades present. "You don't have to think too much about this issue. I have basically completed the relevant work here. I have already worked out the whole system, theory and agreement. What remains is to invest a lot of manpower and implement it in detail."
Click! ! !
All the comrades present felt as if a bolt of lightning had struck the conference room!
Even if you want to strike in advance, you don't do it like this.
The leaders of the Defense Work Committee knew that Gao Zhendong had already had ideas in this regard and must have done some related work in advance, but they never expected that he had already completed the main content of the work. This is unscientific...
"impossible?"
"That's it? He knows what performance we need? What functions?"
"It's possible. Didn't they secretly develop things like email and modems?"
"But……"
"Don't say but, Comrade Gao Zhendong could lie to you?"
"..."
"Comrade Zhendong, is this true?" Not to mention others, even the leaders of the Defense Work Committee felt a little uneasy.
No matter how brilliant Gao Zhendong's record is, this matter sounds so huge and complicated, where does he find the time?
Even if he has extraordinary abilities, his ideas flow like a fountain, his writing is like a god, and he can do research as fast as copying homework, just like when his comrades report to him, he can do two things at the same time, orally narrating an article while carrying out another theoretical deduction work without stopping, but there is still a big problem here.
——How does he know what the comrades’ needs are?
Gao Zhendong knew what he was thinking and explained to his comrades: "Really. The parameters and performance of the network have nothing to do with the needs of the command system. I just started from the network construction and tried my best to complete the design of the network data exchange and transmission system under the existing technical conditions. I started this work after I completed the mail system, simple data transmission, and modem. I worked on it for a long time in my spare time, and the result is not bad."
The military communications institute and other comrades understood his subtext: I am not doing this for you, I am just doing my own research based on my understanding and planning of the network. Whether you are working on the command system or not, I will work on this.
Don't be so touched, it's just a by-product that you can use this thing.
There is another meaning: use whatever you have.
Comrades have no objection to this. Facts have proved that being able to use the technical achievements personally researched by Comrade Gao Zhendong is the best choice under the current circumstances.
From a time perspective, it seems to make sense. The several achievements he just mentioned have been around for two or three years. Such a long time seems to be enough for him to use his "free" time to produce a lot of things.
It may not be enough for others, but it is definitely enough for Comrade Gao Zhendong!
In fact, they didn't know how big the thing Gao Zhendong had in his hands was. If they knew, they would suspect that their views might be wrong.
That thing is huge.
If a person working in IT-related technology in the 21st century were here, they would know what Gao Zhendong was talking about without Gao Zhendong explaining the specific content.
——Complete TCP/IP protocol cluster!
This is a network protocol suite that everyone in the 21st century cannot do without, and is used directly or indirectly.
"Can you tell me more about it?" The leader of the Defense Work Committee said with a smile. At this point, it's not that he didn't believe Gao Zhendong, but he wanted to know what Gao Zhendong had come up with.
This question actually made Gao Zhendong a little troubled. This thing was a bit big and it was hard to say at the moment.
