Do you know what a multi-Wan port Broadband Router is?

The multi-Wan port Broadband Router has always been controversial. What is a multi-Wan port Broadband Router? Only a few wan ports are required for multi-wan port broadband routers. Let's take a look at the following articles with these questions.

What is a multi-Wan port Broadband Router?

The WAN router has multiple physical WAN ports for Internet access, so that the Intranet computer can use multiple Internet access lines through the load balancing function of multiple WAN routers at the same time, greatly improving the network bandwidth. At present, multi-WAN port broadband routers have the advantages of "Bandwidth convergence" and "one-network, multiple-line" applications, which are not supported by traditional single-WAN routers. A router can connect multiple external lines with multiple WAN ports. Using Multiple broadband lines reasonably can optimize many applications and solve many problems. Currently, multiple WAN applications have the following advantages:

1. bandwidth convergence: A Broadband Router with multiple WAN ports can access multiple bandwidths at the same time, and the access line bandwidth can be used at the same time through the load balancing policy to achieve the effect of overlapping bandwidths. For example, WAN1 and WAN2 connect to 1 Mbps of ADSL bandwidth. When the Intranet PC uses multiple download tools such as flash get and Bt to download files, one PC can use two lines at the same time, so that the actual download speed reaches 2 MB!

2. One-network multi-line: A Broadband Router with multiple WAN ports can access different Internet lines at the same time, such as WAN1 connected to China Netcom and WAN2 connected to China Telecom. In this way, the smart policy library built in the router enables the Intranet to access the Netcom service through the Netcom line, and the access to the telecom service through the telecom line, reasonably solved the bottleneck of mutual access between ISPs such as China Netcom and China Telecom, and made your network smooth!

3. Cost Optimization: the same bandwidth is used due to the effect of bandwidth convergence, resulting in lower access costs. For example, the cost of 1MADSL is 150 RMB/month, the cost of 2 m optical fiber is 1000 RMB/month. The effect of connecting two 1MADSL cables is close to that of one 2 m optical fiber, but the cost will be greatly reduced! Because of the line optimization effect, the router can select the line at the cost. For example, the CERNET line can access resources that cannot be accessed by other lines, but the cost is high. At this time, you can connect to the education network line and an ADSL Network. The router will send and receive data that accesses specific education network resources from the education network line, and send and receive data that accesses other Internet resources from the ADSL Network, this will not affect the use effect, but also greatly reduce the cost!

4. Smart backup: when multiple WAN ports are abnormal, the router can promptly transfer network traffic to other normal WAN ports, ensure that line exceptions do not affect network usage, and provide a powerful guarantee for network stability! Xin Xiang's multi-Wan Broadband Router can aggregate multiple broadband lines and distribute the traffic dynamically by means of load balancing to increase the bandwidth of the line and support mixed use of multiple lines. Able to intelligently implement the above applications!

What is a multi-Wan port Broadband Router?

The interface connecting a router to a WAN is called a WAN interface. Broadband routers with multiple WAN ports have changed the "one-to-many" Broadband Access Mode to "many-to-many, this fully satisfies the desire of enterprise users to own more bandwidth at no extra cost. This type of router allows users to share multiple broadband external lines in a LAN, without dividing the internal network into several independent parts based on the number of WAN ports. In fact, its working principle is to distribute various request data transmitted in the LAN to different broadband outlets with preset Load Balancing policies, so as to achieve intelligent dynamic information traffic distribution. As Session requests are distributed and persistent in the LAN, after allocation, the outbound bandwidth of the LAN is increased exponentially.

Do not go to extremes

On the one hand, the highlight of a Multi-WAN port Broadband Router is "many", which some users think that since it is a multi-WAN port, it is necessary to select as many WAN ports as possible. In fact, this is an extreme mistake. On the one hand, the more WAN ports, the higher the product price; on the other hand, you may not need to use too many WAN ports. As mentioned in the article, it is still necessary to meet your actual needs. If you use several WAN ports as Internet cafe users, reasonable configuration is certainly good, but for small enterprises and even domestic users, two WAN ports or even one WAN port can meet the requirements.

On the other hand, users of Multi-Wan broadband routers are mainly Internet cafes, communities, schools, and enterprises. The network size is generally small, so they are concerned about the price, this allows some users to start from the price when selecting the product. The result is that the products with low performance and no quality guarantee are bought. What the reporter wants to say is that performance is very important for the multi-Wan port Broadband Router. It should also be the primary consideration for selection, then the function, and the final price. Because in the current market environment with rich products and fierce competition, the price can basically be "price-based ". Low-quality multi-Wan port broadband routers lose the meaning of "Multi-Wan port.
