Network switch (switch) - a special device that serves to integrate various equipment (servers, computers, routers, etc.) in the network. With its help, you can quickly, simply, inexpensively and technically integrate a huge number of different network equipment at the highest possible speeds. Its main difference from more complex routers is that the network switch does not register packet routes from one point to another. Its main task is simply to combine two disparate points among themselves by means of the logic already registered inside it.
A network switch can be of several types.
The simplest is a device that allows you to physically combine two or more channels with each other to ensure the transfer of data flow from one device to another. At the same time, a third-level network switch (with a routing function) is able to perform almost the same functionality as more complex routers. With their help, you can register virtual private networks, aggregate channels, configure the shaping of data streams, and recognize the transmitted protocols by type.
