How to avoid network congestion

Q: How can we effectively avoid network congestion? Our application is the extended star topology. After the 16 P switch is installed, there is less congestion, but the network congestion still occurs from time to time.

We have four 24 p routers and a 24 p hub. It seems that people suffering from network congestion often have to link with 3com hubs.

Another question is, how can I remove the Domain Name Server from the master server?

A: The first step to solve network congestion is to remove all the hubs. They are only the source of the problem and do not play any other role.

When a frame enters a hub, it will go out of all ports, which will cause unnecessary congestion in your network, A vswitch can only send frames to the correct port of the target machine. All ports on a hub belong to the same congestion domain. In contrast, each port on a vswitch belongs to a congestion domain.

In many cases, we can see that troublesome hubs cause a lot of congestion and affect most of the work areas and servers in the network. So remove these hubs.

Second, your website has about 120 ports, which is a large number for a common network. I usually divide the networks of more than 50 hosts into smaller parts, which reduces network congestion.

It is a good idea to divide networks into smaller parts by a widely used wireless LAN. You can use a vro or a layer-3 Switch to create a smaller distributed network.

If you want to learn more about the connection between the wireless LAN and the LAN, you can visit my website for detailed analysis.

You also mentioned that you want to remove the Domain Name Server from the master server. It is not a good idea to remove a Domain Name Server from the master server according to your network architecture, especially when you plan to run Microsoft Active Directory, it requires a Domain Name Server.

However, if you have already set up a working group, removing the Domain Name Server will be fine.
