How to formulate a data transmission delay model?

Question

Computer networks

Please help with this question: how to build a delay model (delay time) of data transmission? Perhaps there is literature in which this model is described.

Answer 1

There is a whole field of science dedicated to modeling, as well as systems theory .
As for the data transfer delay model, you need to proceed from the goals and conditions of your model.
Roughly speaking, you can assume that the delay is always 12ms.
On the other hand, you can build a distribution of delays, approximate it with some law, for example, normal, and then extract the parameters of the law: mean and spread, 12±5.
Also, no one bothers you to study the physical meaning of the delay and derive the appropriate formula.
Well, there are many more ways...

Answer 2

Here .
The delay can be in the device (intermediate devices and their components - ports, software devices, processors) and the transmission medium.
