I haven't been on this 51cto website for a long time. Write about what you once felt.

The first is the experience of the switch. It's a real exchange place, where you can exchange your own data. The specific application is that in the environment where there are two networks to work, set their own parameters, they will automatically complete the data exchange work. There are two networks in the work: one is the Internet, to obtain the ip; automatically, the other is the private network, specify the ip manually. The general practice is to use two exchanges to connect to their respective computers. But I also experimented with using a large switch with many ports, connecting them (computers belonging to two networks) and uplinks, and finally working, as if the two switches were working. To put it more colloquially, it is called "each exchanging its own data".

The second is the new understanding of the hub function of the switch. There was a need for both networks to be connected to an office, but there was only one port on the wall. How was it solved in the end? What people usually think of is that the switch can be a network port adapter with more than one port, that is, if there is only one port to expand, it can connect multiple computers. This time it is to connect two networks. The computers of the private network and the computers of the external network are connected to this port through the switch, and the other end is separated by a small switch into two networks, each connected to its own uplink. In other words, the switch can turn more than one turn, and it can also turn one more. This example is to use a physical line to achieve multi-to-one, to complete the transmission of multiple networks.
