Six Golden laws: Rational recommendations for Internet cafe Routers

How can I select a suitable Internet cafe router? Here are some suggestions for choosing a router in the Internet cafe. This section describes WAN port, technical indicators, security performance, and brand.

At present, there are many types of router products available, including enterprise-level routers, SOHO routers, home routers, and dedicated-bandwidth routers. There are also different types of vrouters, such as dedicated game-type vrouters, dual-WAN ports, and enhanced-type vrouters. In addition, the product performance, brand, and price are all different. This increases the difficulty of purchasing Internet cafe owners.

1. What router should I choose for Internet cafes?

At present, there are fewer and fewer Internet cafes Using proxy servers. Nowadays, with the popularization of online games, video-on-demand applications, routers have been widely used in Internet cafes. The following are some suggestions for Internet cafe routers.

Recommended Purchase: before purchasing a vro, the consumer must fully consider the actual size of the Internet cafe, for example, having 30 ~ For Internet cafes with 50 computers, you can select ordinary SOHO-level routers with low investment costs. However, in this case, the product's data processing capabilities are limited, and in the case of high data volumes, it is prone to disconnection and other situations; 50 ~ For Internet cafes with 100 computers, you can select a dedicated network bar router to achieve stable and high-speed access and meet the needs of online games, on-demand video streaming and other applications.

2. Is one WAN port better or multiple WAN ports better?

At present, there are many vrouters with multiple WAN ports (WAN interfaces) on the market. Are there any better vrouters with multiple WAN ports than those with single WAN ports? What are the advantages of vrouters with multiple WAN ports?

Recommendations: Compared with a single WAN port router, a multi-WAN port router (figure 1) can multiply the egress bandwidth, backup lines, and enjoy more services. Take a dual-WAN router as an example. In terms of outbound bandwidth, if two 10 Mbps broadband lines exist, the bandwidth can theoretically reach 20 Mbps; the function of line backup is to re-allocate data traffic to a non-Faulty port when an Internet access line fails, so that the entire network will not be interrupted, this is essential for Internet cafes that often run for a long time without interruption. to enjoy more services, different ISPs provide different on-demand video and game services, for example, an internet cafe applies for both Telecom broadband and tietong broadband, so that they can enjoy different services.

3. Practical Technical Indicators

There are many technical indicators to measure the quality of a vro, such as hardware indicators, packet forwarding rate, and common software indicators such as Internet access methods, DHCP servers, and virtual servers.

Recommended Purchase: only 50 ~ Recommended for Small and Medium-sized Internet cafe routers with 100 computers: Pay attention to the hardware and software technical specifications of the product when purchasing a router. In terms of hardware indicators, the main focus is on the CPU type of the router (Figure 2), the CPU is mainly responsible for exchanging route information, route table search and packet forwarding. The CPU type of different products is different, such as TP-LINK TL-R490E using Intel IXP 266 processor, while CISCO 2610XM using Motorola MPC860 40 MHz processor. In addition, important hardware indicators include Flash Memory and memory. Generally, the larger the flash memory and memory of the router, the better. When the product price is roughly the same, select a vro product with large flash memory and memory.

In terms of software indicators, general technical indicators can be achieved by routers. When purchasing a vro, pay attention to the throughput of the vro. The throughput of a router is the packet forwarding rate. It refers to the ability of the router to forward data packets. The larger the value, the better. The unit is usually pps (Thousands of packets per second ~ For 100 Internet cafes, you can use dozens of Kpps products in the packet forwarding rate.

4. Security performance is critical

Today, when viruses and hackers are rampant, the Internet and LAN have become a breeding ground for viruses and hacker attacks, especially in Internet cafes. To enable Internet cafes to run in a secure network environment, the selected router product must have sound security performance.

Recommended options: 50 ~ Recommended for Internet cafe routers of 100 people. When purchasing a router, pay attention to the security performance of the product, including whether a firewall is built in, whether domain name filtering is supported, whether MAC address filtering is supported, whether DoS attacks can be prevented, and whether user access permission management is supported. For example, the domain name filtering function can be used to filter the domain names of websites that are prohibited from access, so that some unhealthy websites with malicious code cannot be accessed in Internet cafes; the built-in firewall can avoid SYN overflow and IP Spoofing. When purchasing a product, if you have the conditions, it is best to manually set the security options one by one, and then select a router product with simple security settings and comprehensive security performance.

5. manageability cannot be ignored

In Internet cafes, managing dozens, hundreds, or even hundreds of computers is not a simple task. Once a virus attacks on the internet, maintenance may be very troublesome, therefore, when purchasing a router, pay special attention to the manageability of the product.

Recommended options: 50 ~ Recommended for Internet cafe routers of 100 people: in addition to the security management functions such as Internet access permission management and MAC address filtering mentioned above, the manageability of A vro is also manifested in the support for Chinese configuration interfaces, ease of use, Web management, and DHCP servers. When purchasing a product, you can view the product manual, connect the product to the computer, and open the configuration interface for trial. Select a simple and easy-to-use product that supports the Chinese configuration interface, and assign an IP address to the computer in the internet cafe through the DHCP server function, by managing common network applications, You can restrict and manage access to these applications to ensure the security of the entire Internet cafe.

6. brands are also important

Currently, there are many brands of Internet cafe routers available on the market. The recommended brands include domestic TP-LINK, TENDA (tengda), AI, and Jin Lang, there are also foreign CISCO and NETGEAR.

Recommended Purchase: When purchasing router products, try to select products of some well-known brands. The quality of these products is generally guaranteed and there is a sound after-sales service, this can reduce the worries of Internet cafe owners. Do not use images cheaply. Select an unknown product.
