With the development of modern society, there are more and more modern "lazy people", and those lightweight and labor-saving "lazy products" are increasingly welcomed by modern "lazy people". Nowadays, switches are becoming more and more "stupid", such as the omni-directional QS-5xx series, which has advanced performance such as full duplex and exclusive bandwidth. All ports can be automatically detected according to the speed of the connected equipment, and 10M/ 100M is adaptive, and different network cards can be connected to meet different network speed requirements. Store-and-forward mode can check the security and correctness of data packets before forwarding, reduce unnecessary data forwarding, filter network storms, and avoid possible network paralysis and performance degradation, which is very suitable for the network environment with average link quality. QS-508 has simple installation, intelligent website management, and can quickly identify network members. In order to facilitate the user's operation, it has rich indication functions, and the all-round QS-508 can display the network running state intuitively and clearly. And it has the self-learning and adaptive function of 10/ 100M, which is "stupid" so that users don't have to worry about the complex network application environment, and all settings are done by the switch itself.
The difference between switch and fool switch is introduced;
Before explaining the intelligent switch, let everyone know what an intelligent switch is. There is also the working principle of intelligent switch. What is the difference between intelligent switch and fool switch? Whether it is manual switching or program-controlled switching, it is to transmit voice signals.
As the core equipment of Internet cafes, switches can be regarded as overpasses for data transmission between computers. Undoubtedly, the performance and capacity of overpass will fundamentally affect the transmission rate of the whole network. For the owners of Internet cafes, switches are relatively expensive network equipment, therefore, you must choose carefully when purchasing switches.
Internet cafe owners pay attention to the stability, high speed and capital investment of the network. Therefore, the following principles should be followed when purchasing Internet bar switches: stability is the overriding overall situation, and stability should be the basic principle to be followed when purchasing Internet bar equipment.
Intelligent switch is no exception. The performance of the switch can be very poor, and the bandwidth can be very narrow, but it must not break down frequently, especially it must not be dropped frequently. The reason is simple, once the intelligent switch fails. All the computers in the internet cafe will be disconnected immediately.
"Net" is just a hollow name. The intermittent network environment will soon drive consumers to turn to competitors. High cost performance is the goal of car owners. "Let every penny be spent well" is the pursuit goal of every operator. The principle of cost performance is mainly embodied in the following aspects:
1. Port density
When all performance parameters are basically the same, the higher the port density of intelligent switch, the lower the cost of each port. In other words, a 48-port switch is cheaper than two 24-port switches. Therefore, switches with high-density ports often have higher cost performance.
2. Performance and function
The better the performance, the richer the functions and the higher the price. In fact, because the scale of internet cafes is often not very large, various network applications are not particularly rich, and the requirements for network security are not very high, so the general 100Mbps fool switch can take on the heavy responsibility.
Consider differences
Some switches (central switches) are used to connect other switches and servers, while others (workgroup switches) are directly connected to computers. Therefore, products with different performances should be selected for switches in different positions. Only in this way can we give full play to the highest performance of each device. When there are more than 200 computers in Internet cafes, it is recommended to buy a three-layer switch as the central switch.
4. manufacturer brand
There are switch manufacturers in the United States, Chinese mainland and Taiwan Province Province of China. Among them, American products have the highest price, the richest functions and the strongest performance, followed by products from China, Chinese mainland and Taiwan Province. Because Internet bar switches don't need many functions, well-known brands in Chinese mainland are often the most cost-effective.
The overall performance is that the owner pursues the harmony, matching and compatibility of the switch. Port rates should match. If the central switch adopts 1000Mbps port and the workgroup switch adopts 1000Mbps port, then it is undoubtedly a waste to adopt1000 Mbps port.
The technologies adopted by different brands of switches should be compatible with each other and follow the same international standards, thus making network management and technology realization possible. In a word, the switches should be connected harmoniously to give full play to their performance. Rational purchase and reasonable budget are the principles that a successful Internet cafe owner must follow. Therefore, when purchasing switches, we should seriously consider the following issues according to the investment quota and the actual needs of Internet cafes:
Intelligent switch refers to network management switch, and fool switch refers to non-network management switch. With the help of management function, the switch can realize various switching technologies, set up complex network applications, control users' access to the switch, ensure network security and improve network transmission efficiency.
The central switch of large Internet cafes should have management function, which is used to divide VLANs and realize communication between VLANs. However, the management function is usually ignored when buying workgroup switches, and cheap fool switches can be used. 1000Mbps or 100Mbps.
Undoubtedly, the 1000Mbps port can provide higher network bandwidth and is more suitable for multi-channel concurrent access and multimedia data transmission. However, its port price is often 20 times more expensive than 100Mbps. Therefore, unless there is a special need, it is recommended to choose 100Mbps switch.
