How is network performance calculated?

Question

Computer networks

Could recommend the literature which describes, with formulas, the calculation of network performance. Or maybe there are already finished works.

Answer 1

You need to study the theory of mathematical modeling (sometimes called the theory of computation or computer simulation) and the theory of queuing , which is based on the theory of probability. Next, delve into GOSTs , which set the main parameters and requirements for calculations.
And then you can read the laws in which it is written in black and white that there are no specific requirements in the legislation for networks of your type , so no one cares, and the quality of communication is regulated solely by the laws of the market .
Well, let me answer the next question.
1) Types of users are distinguished.
2) Statistical data is examined and traffic models are built that are different for each type of user.
3) A model of the network is built, on the basis of which its properties are calculated
. 3a) In the harsh 20th century, multipage formulas of the theory of probability and queuing with integrals and factorials were written.
3b) Now it is easier to create a computer simulation model.
3c) The most advanced ones went to economy 4.0, created a digital twin of the enterprise and forced the neural network to do everything on its own. But, most likely, you do not fumble in neural networks (a sort of large equation with 15 million input parameters), you will not be able to choose the parameters and you will not get adequate results.

Answer 2

It is possible to measure the characteristics of a particular connection The
characteristics of the connection between two nodes
A "network performance" - has no general meaning. You need to understand what exactly you need.
Tell me. road performance in the city how to measure?
The average temperature in the hospital will turn out to be meaningless.
