Three Most Valuable Tips for purchasing vswitch Products

The three most valuable tips for purchasing vswitch products include port, switch mode, and transmission mode. With the continuous construction and popularization of Campus Networks, the number of dormitories with more than two computers is also increasing, and the networking of students has become a fashion. At present, wireless network products in the network product market are falling, and the price of routers is also falling, directly forcing the household switch market.

But does a home switch with simple operations, convenient use, and low price really lose its competitive advantage? In fact, for a single campus network, whether it is campus network sharing, file transmission, or program link, it is completely supported by a household switch. Therefore, for students with low budgets, selecting switch networking is undoubtedly the most economical solution, saving unnecessary expenses.

Switch product purchasing skills

Vswitch is an exchange technology product featuring high cost performance, simple and practical performance, and high port density. Vswitches can be divided into Ethernet switches, Fast Ethernet switches, Gigabit Ethernet switches, FDDI switches, ATM switches, and wildcard ring switches in terms of transmission media and transmission speed. Here we mainly talk about the use of Ethernet switches in student dormitory.

Although vswitches are cheap and easy to operate, the functions of the products of the same brand are basically the same. However, even products with the same features may have different performance and prices. Therefore, you should also pay attention to the selection during the purchase.

Switch product purchasing tips: Port

Generally, the more ports a vswitch has, the more computers it can access, and the higher the price. For the student dormitory network, it is enough to select five or eight SOHO switches. These vswitches generally include 5 ~ 8 RJ-45 ports and an UPLink (cascade) 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.

Switch product purchasing tips: Transmission Mode

Generally, vswitches support Full/half-Duplex adaptive modes. The Full Duplex mode can receive and send data at the same time, and the data stream is bidirectional, which improves the network transmission efficiency; the "Half Duplex" (Half Duplex) mode cannot receive and send data at the same time, and the data stream is unidirectional.

Switch product purchasing tips: Switch Mode

Currently, vswitches use two main exchange modes: "Storage forwarding" and "Direct-through forwarding": "Storage forwarding" is the process of forwarding after the vswitch receives all data packets, it can detect data packet errors and support the exchange of input and output ports at different rates, but the delay in data processing is long.

"Storage forwarding" is one of the most widely used technologies in the computer network field. Most switch product purchasing techniques now support this technology. "Forward through" means that the switch has started to forward data before it receives the entire frame, which can reduce the latency. Low-end switches generally only support one type of exchange, that is, storage forwarding or pass-through forwarding.
