Comprehensive Explanation of cost-effective dual-WAN Port Routers

With the development of China's routing industry, dual-WAN Port Routers are also widely used. Here we mainly introduce a cost-effective dual-WAN port router. Currently, many Internet cafes use dual-WAN Port Routers. The dual-WAN port router is very familiar to Internet cafe operators. Simply put, a dual-WAN port router is a router with a dual-wide access port, this type of router has many benefits:

1. Increase the egress bandwidth. Taking TP-LINK's dual WAN port router TL-R480 + as an example, using two ADSL or Ethernet broadband lines, because the two WAN ports can be load balancing, therefore, the total egress bandwidth is doubled to the original one. At present, both ADSL and 10 M Ethernet bandwidth have very low monthly subscription fees, and the costs of applying for more bandwidth are limited, bandwidth grows exponentially with limited costs, which can be achieved for larger networks.

2. Line backup. Using a multi-Wan port router, applying for multiple lines and using multiple Modem, these lines can also be of different carriers, such as China Telecom's ADSL and 10 M Ethernet of China Netcom, when an ISP, cable, or Modem fails, the data traffic will be re-allocated to a non-Faulty port, and the entire network will not be interrupted.

3. Provide more content services. Different ISPs provide different game, chat, video-on-demand, and other services. These different content services are placed on the ISP Server. to enjoy these services, you must apply for corresponding ISP access. To provide multi-ISP content services, you must apply for multi-ISP access and use a multi-Wan port router. Actually, how does this type of router work? What will happen if two different bandwidth lines are connected to the dual-WAN router? Many people are concerned about this issue. I will briefly talk about the working mode of Dual-WAN Port Routers.

1. Normal Mode: when the general router function can meet your needs, you only need to select the normal mode in the connection settings on the WEB page. At this time, WAN1 really works, just like a common router.

2. Backup mode: When WAN-1 is invalid or disconnected, WAN-2 automatically starts to work (saving connection costs). In this way, even if WAN1 cannot work, WAN2 can connect to the Internet, the disconnection caused by WAN1 failure is avoided.

3. Balanced mode: The WAN1 and WAN2 lines can be used at the same time. The balanced mode includes three traffic configuration methods:

Duplex router configuration: AF420B will automatically allocate traffic to the WAN 1 and WAN 2 lines without additional settings.

Traffic router configuration: when the traffic of WAN 1 exceeds the "Traffic preset utilization value", WAN 2 is automatically enabled to share the traffic of WAN 1, avoiding network paralysis caused by excessive WAN1 burden.

Application router configuration: network traffic can be allocated according to the application or communication protocol used. For example, if WAN1 is connected to education network and WAN2 is connected to ADSL, data is exchanged from WAN1 when you want to access the domestic source of education network. When you want to access public network or international network, data is exchanged from WAN2. This greatly shortens the network transmission time and saves network fees. You can also use "application configuration" to distribute FTP and HTTP to WAN1 WAN2 and obtain the corresponding bandwidth.

In addition, the price is also a concern of many people. A few years ago, because there were few manufacturers producing such routers and such technologies were relatively new at that time, the price of a Multi-Wan port router was very high at that time. However, there are now more manufacturers and prices are also lowered. Currently, the prices of Multi-Wan Port Routers are generally between one thousand yuan and two thousand yuan, the specific price is related to the function of the product and the manufacturer. DI-602LB provides 2 10 M/100MWAN broadband ports and 1 10 M/100 MLAN broadband port, WAN broadband ports can be connected to 2 ADSL or CABLE lines at the same time, it has the function of automatic load balancing.

The unique line redundancy feature gives DI-602LB excellent stability. In dual-line ADSL, even if there is a problem on the first line, it will not interfere with the normal operation of the other line, so as to ensure that the network is connected at any time. DI-602LB can bring more convenience for users to manage internal bandwidth. It has the bandwidth management function, which allows managers to limit the maximum bandwidth of applications that may be used on each WAN bandwidth port, so as to configure the network bandwidth according to different requirements, it is easy to control the purpose of network resource allocation. After applying the bandwidth management function of the DI-602LB, the manager can set the corresponding percentage for different applications, the DI-602LB router will automatically assign the bandwidth to the application according to each WAN bandwidth port, in this way, the maximum bandwidth that FTP can use is limited to ensure the smooth running of other applications. This function enables enterprises to have great flexibility when connecting networks.

The DI-602LB further optimizes security and provides firewall functions, allowing users to run various applications in a secure environment. Compared with the current access method, DI-602LB smart duwan port Broadband Router is undoubtedly advantageous cost and performance advantages, can be called the ideal choice of enterprise users.
