Users must look at tips for purchasing household Switches

Currently, many household switches have reached 100 Mbps, which can meet the needs of most users. Currently, switches have quickly replaced hubs and become the preferred product for users to build networks, let's make a purchase for you! In the modern network design, the use of Ethernet switches can significantly improve the application performance of the entire user network. For this reason, household switches are increasingly favored by more network users.

In addition to the advantages of speed, switch devices can provide more functions than traditional network sharing devices. As the competition in the switch market becomes increasingly fierce, the price of switch equipment is more acceptable to users. Currently, domestic switches have quickly replaced hubs and become the preferred product for users to build networks.

Differences between a vswitch and a hub

To get a deeper understanding of the switch, we need to first understand the difference between the switch and the hub: If we regard the hub as a built-in Ethernet bus, A household switch can be considered as a multi-bus-exchange matrix interconnection. Technically, a vswitch attaches each port to a backplane bus with a high bandwidth (at least one order of magnitude higher than the port bandwidth) and connects it to a vswitch, the encapsulated data packet that is lost from the port enters the switch through the backplane bus. You can use both forward-through and store-and-forward methods to exchange data.

In addition, vswitches are more cost-effective. In the past, the high price of domestic switches was the main reason for us to choose a hub. With the development of exchange technology in recent years, the price of Ethernet switches has dropped sharply. To date, the price/performance ratio of switches far exceeds that of hubs.

Purchase

The prices of domestic switches on the market range from RMB to RMB and RMB, and there are many brands. SOHO switches are a good choice for ordinary home users. SOHO switches are almost all-in-one desktop switches with different sizes. Generally, they provide 5 ~ 8 10/100 Mbps adaptive ports. Compared with medium-and high-end switches, SOHO switches generally do not support network management and do not manage or set up them. The number of computers to access is very limited, but the price is very low, applicable to home networks in a simple network environment. Next, I will introduce some precautions for the purchase.

Port type

Generally, the larger the number of vswitch ports, the higher the price of the vswitch, the more computers you can connect. For home users, it is sufficient to select five or eight SOHO switches. A vswitch generally has N RJ-45 ports and at least one UPLink port. In addition, you must pay attention to whether the port supports MDI/MDIX. With this function, you can automatically establish a line-order connection on the cascade switching device, without the need to manually configure the line-order.

Transmission Rate

Currently, the transmission speed of mainstream household switches is still 100 Mbps, which can basically meet the needs of families. Although the gigabit network technology has developed rapidly in recent years, it is not practical. In the market, it is still dominated by 10/100 Mbps adaptive switches. However, considering the needs of future network upgrades, you can choose 10/100/100/1000 Mbps adaptive or Mbps adaptive Gigabit Switch, but the price is high.

Price

The price is undoubtedly the most important consideration for the majority of users when purchasing switches. Currently, the price of domestic switches suitable for household or small office networks is almost the same as the price of the Hub to be "obsolete, for example, the price of a 5-port 10/100 Mbps adaptive switch is roughly 100 ~ Except for products other than 300 RMB ). Generally, the more ports, the higher the speed, the higher the bandwidth, and the more powerful the network management function, the higher the price of switch products. Eight SOHO switches are enough for families.

Brand

In the domestic market, low-end switch products cover many domestic brands from foreign network giants such as 3Com to D-Link youxun Network), TP-Link and dingxing. When purchasing a household switch, pay attention to the brand awareness of the product supplier, user reputation, after-sales service and quality assurance of the product.

Shape

The shell of the SOHO switch is generally packed in plastic or iron case, with little price difference. The shape is usually small and Mini. You can choose according to your preferences.
