Tips for using vswitches for shortest reading (1)

Tips 1)

In modern network designVswitchIt can significantly improve the application performance of the entire user network. Now, the speed of many household switches has reached 100 Mbps, which can meet the needs of most users.

For this reason, domestic 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.

The difference between a vswitch and a hub is to further understand the difference between a vswitch and a hub: If we regard a 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, encapsulation data packets thrown in by the port enter the home 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.

The prices of household 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.

They are of different sizes, usually 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.

The port type usually has more ports. The higher the price of the switch, 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.

The transmission rate 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.

The price is undoubtedly the most important consideration for the majority of users when purchasing switches. Currently, the prices of household switches suitable for household or small office networks and the Hub to be "obsolete) the price is almost the same, for example, the price of a 5-port 10/100 Mbps adaptive home switch is roughly 100 ~ RMB 300 (excluding foreign products ).
