Building a telecommunications system based on routers allows you to use traffic prioritization to improve the quality of user traffic, regardless of network technology. This new feature, compared to networks built entirely on hubs, is a consequence of the fact that routers buffer packets before they are sent to another port. The router usually leads for each input and output port not one but several queues, each queue having its own processing priority. The efficiency of the network depends on the capacity of the ...

Computer simulation is substitution of original object by another one in order to obtain information about the most important properties of the original object using the object model. Depending on the purpose, the simulation can be made on two levels: on the qualitative and quantitative. Accordingly, descriptive or constructive models are used. Mathematical modeling is always performed quantitatively using design patterns. This article describes the modeling of computer networks and their parameterization. One of ...
