Maximum Optimization for Internet cafes: medium-sized Internet cafe switch procurement solution

Some time ago, questions about how to apply for a ban on Internet cafes were also excited in some regions. The question about how to apply for a ban on Internet cafes is more of a social problem, we can't discuss it any more here. From the standpoint of professional network product media, we plan to talk about the internet cafe from the aspect of equipment.

Even though the application to lift the ban on Internet cafes allows many investors to see business opportunities, the Internet cafe industry is now in a standardized and large-scale direction under the guidance of national policies, this is conducive to the national management of the Internet cafe industry, and inevitably leads to increased competition in the internet cafe industry. In addition, with the continuous development of computer costs and the increasing popularity of broadband networks, the Internet bar industry is mainly intended to attract a large number of users and achieve better financial return. We must make more efforts in terms of business strategies and infrastructure.

Today, it is said that switches are a very basic but important part of Internet cafe networking devices. Switches are the hub for data transmission between computers in Internet cafes. Many online video applications of LAN games and Internet cafe servers depend on switches to a large extent. In addition, if you add some special functions for Internet cafe applications to the vswitch, you can also enhance the management and monitoring of the Intranet of the Internet cafe to improve the network access capability.

According to relevant experts, in the future, Internet cafes will be categorized from the business scope and service content. According to their service content, the Internet cafe will form a market segment with special characteristics and personality, and provide professional and comprehensive services for different users. The development of chained Internet cafes will become the development trend of the domestic Internet cafe industry. Under this trend, Internet cafes will become functional, value-added, and popular in the future.

According to the current situation, there are several independent Internet cafes, regional chain Internet cafes, and national chain Internet cafes in China, and the scale is also uneven. Therefore, we should choose vswitches of different technical levels based on the differences in scale and business model. Generally, most small and medium-sized Internet cafes use layer-2 or layer-3 switches due to their scale and exchange restrictions. Generally, they are non-Network-managed switches with fixed ports. In terms of port speed, Mbps can basically meet the needs; in terms of port expansion, the cascade method with lower costs is generally used. For larger large-scale and chained Internet cafes, three-tier switches or higher-end three-or four-tier switches are required, and network management and stackable switches with modular ports are used. In terms of port speed, 1000 Mbps is required.

In terms of functions, Internet cafes with a certain scale must be divided into different VLANs for different applications to ensure network security and manageability. Therefore, the selected core device must have a gigabit layer-3 line rate forwarding function to ensure long-term operation. Internet cafe switches should support port-based VLAN, QoS, IGMP/GMRP multicast, 802.1X/AAA/RADIUS Authentication, etc. In the future, vswitches require high speed and high security. It supports browsing, chatting, downloading, on-demand video, online games, and other services.

The product manager of a well-known network equipment brand in China believes that the role played by Internet cafe switches has evolved from simple data exchange to diversified aspects such as content classification, management implementation, and software cooperation, therefore, Internet cafe switches require many key technologies, such as full-line rate packet forwarding performance, port scalability, and QoS differentiation, at the same time, various chips, electronic components, power supplies, circuit boards and other devices of the switch equipment are required to have the ability to withstand voltage and current fluctuations, withstand lightning strikes, and resist high and low temperatures, able to handle various management and configuration functions with friendly man-machine interfaces. In addition, the vswitch that connects to the desktop must have at least 1 Gbit/s of uplink ports. Otherwise, bottlenecks may occur, however, the requirements for backbone-level equipment tend to be three-layer switching and full-Gigabit ports.

After discussing with some network equipment dealers and technical engineers of the system integration company, we may also summarize some features of Internet cafe switches: high performance, stability, and high speed, at the same time, the price is low and medium to facilitate expansion. When purchasing switches, the majority of Internet cafe owners should also try their best to avoid selecting high-grade products. The principle is practical and sufficient.

Next we will introduce several products recommended by system integrator technicians based on the scale of medium-sized Internet cafes:

Network Topology

As the number of Internet cafes is not small, you cannot directly use a desktop switch. Instead, you must use a topology (a relatively basic medium-sized network structure, advanced Internet cafes can also be expanded on this basis) to achieve scale expansion and enhanced management. Therefore, the following products, such as network management switches, are suitable for VLAN division and Management of lower-Layer Networks. These devices do not directly connect to terminal computers, but connect servers and lower-layer desktop switches; in addition, some vswitches are desktop switches that are directly connected to computer terminals. We will also differentiate them based on the purpose of the vswitch.
Gigabit network management switch:
