Some Key Parameters Of Industrial Network Switches

Industrial network switches are suitable for application in a variety of environments, almost everywhere. In addition, it also includes industrial monitoring, smart street lights, wind power generation, rail transit, etc. It is only necessary to recognize the brand when purchasing such products. Although the price of high-quality products is high, they can also be better guaranteed in terms of application quality.

When most people buy industrial network switches, they will decide from the parameters. In fact, many people don't know much about product parameters or even don't look at them directly. In fact, when purchasing industrial network switch, the parameters of the product are particularly important. Only after understanding the performance of the product can we understand the quality of the equipment. Now let's understand some key parameters of industrial network switches:

1. Forwarding rate

Forwarding rate (throughput): throughput (Mpps)=number of 10-gigabit ports * 14.88Mpps+number of gigabit ports * 1.488Mpps+number of 100-gigabit ports * 0.1488Mpps. If the nominal throughput of the industrial network switch is greater than or equal to the calculated value, the line speed (data transmission speed on the transmission line) can be reached during the three-layer switch; The theoretical throughput of a gigabit port with a packet length of 64B is 14.88Mpps (=1000000000bps/8bit/(64+8+12) bytes)

2. Transmission rate

The transmission speed of the switch refers to the data exchange speed of the switch port. Now there are several common types, such as 100Mbps, 1000Mbps and 10GMbps.

3. Operating temperature

There is no need to worry about the working temperature, because the temperature span of this kind of products has been very large, from minus 45 degrees to 85 degrees without any problems, even in extremely hot or cold environment, it will not affect the product's own performance, so people's requirements for the environment are not particularly high.

4. Number of MAC address tables

The number of MAC addresses refers to the maximum number of MAC addresses that can be stored in the MAC address table of the industrial network switch. Each port of industrial network switches of different grades can support different MAC numbers. At each port of the switch, there is a need for sufficient cache to memorize these MAC addresses. The size of the cache capacity determines the number of MAC addresses that the corresponding switch can memorize. The more advanced industrial network switches can remember the more MAC addresses.

5. Relative humidity

If the industrial network switch requires 5%~95% humidity, when the humidity is too high, it will have a negative impact on the performance of the product itself, and even cause corrosion, because all kinds of equipment are not easy to be stored in a humid environment. If the relative humidity is too low, it means that the air is dry, which is very likely to cause electrostatic problems, and will also cause unsafe application environment.

6. Authentication method

The industrial network switch can be normally produced only after being certified by the relevant departments. The authentication methods required here include 3C authentication, the network access license of the Ministry of Industry and Information Technology, and the detection report of the Ministry of Public Security. If you plan to purchase, the authentication method is also an important weighing indicator.

In short, when purchasing industrial network switches, everyone has different points of view. In fact, most industrial network switches have their own advantages. When purchasing, people can fully check the product performance, and communicate the purchase matters after confirming that the product performance is stable and all parameters meet the requirements. If the product parameters do not meet the requirements, try not to choose this product.
