How can I solve the problem of too many vswitches in series?

How can I solve the problem of too many connection switches in the internet cafe? This problem is not uncommon in Internet cafes. It is generally because of the small size of Internet cafes and limited investment in the early stage. In most cases, multiple switches are connected in a hierarchical manner.

In this case, a node failure will cause a fault across the network, because data transmission needs to pass through every node on the ring, such as a node failure, it will cause a network failure across the network.

Because the working principle of the private switch for the Internet bar is that after receiving the data, address the MAC address table first. If it is found that the MAC table does not exist. The data will be broadcast out, transmitted to the upper-level switch through UPLINK, and then repeatedly broadcast by the above switch to send the data to the target client.

Because the MAC address table of the vswitch is limited and is dynamically updated, it does not store too much information, while there are many computers in the internet cafe and the network usage of the computer is high, A large amount of unnecessary broadcast information will flood the whole network, reducing network performance.

In particular, some internet cafe billing management software constantly communicates with the client and constantly checks the working status of the client. When such data packets break out, the entire network becomes very stuck. This situation is even more aggravated by these incorrectly connected vswitches.

Communication between Internet cafe clients relies on Level 1 switches. The primary switch is mentioned here. The main switch is also called the core switch because it is the center of the entire topology. The main switch is very important.

On the one hand, it is necessary to quickly transmit data traffic from the Internet, and on the other hand, it is necessary to handle large-volume communication (movie servers and file servers) between switches and servers at different layers ), effective priority control and broadcast storm control are also required for the entire network.

How can I solve the problem of too many connection switches in the internet cafe?

The first step is to change the connection mode, with a primary switch as the center point. In view of this, the primary switch must be a switch that can be managed and monitored. Moreover, the Internet cafes now have installed security audit devices set up by the network supervision department. Port listening and mirroring functions are essential, which puts forward requirements on How to purchase the primary switch.

Network Management switches can achieve the following: SNMP-based network information acquisition, Port Mirroring, port speed restrictions, global broadcast storm suppression. Qos traffic priority control.

Advanced vswitches also support Port Link aggregation, spanning tree protocol, and port priority control.

Correct use of these features is good for the network. Therefore, using a good connection method and a good master switch is good for the stability of your entire Internet cafe network.
