What Is a WAN Diagram?

As early as 2000, Beijing Xin Omnidirectional engineers researched a multi-homing (Multi-Homing) solution and found that there was a huge market demand for multi-WAN devices with all Ethernet protocols in China. Along with the successful development of Xin Omnidirectional products, the first multi-WAN router in China was born in 2002, and the first multi-WAN broadband router in China was named NuR8021. The multi-WAN router has multiple WAN ports physically as external network access, so that the internal network computer can use multiple external network access lines at the same time through the load balancing function of the multi-WAN router, which greatly improves network bandwidth. At present, multi-WAN routers mainly have the advantages of "bandwidth aggregation" and "one network with multiple lines", which cannot be achieved by traditional single WAN routers.

Multi-WAN router

The router has multiple

Fake multi-WAN means that the router also has multiple physical WAN interfaces, but the router does not use bandwidth aggregation as its purpose when processing Internet data, but uses a function called "IP balancing". Although this is also a multi-WAN solution, the actual application does not have the effect expected by users at all.

"IP balancing" is similar to simply "assembling" two routers with single WAN ports. It looks like multiple WANs. Fake multiple WANs mainly refer to the deceptiveness of routers in multiple WAN processing strategies. When "IP balancing" is used for a false multi-WAN operation, the line is allocated based on the IP of the intranet PC instead of the Internet access request in SESSION. In layman's terms, counting people's heads, PCs 1, 3, and 5 take WAN1, 2, 4, and 6 take WAN2. Obviously, an intranet PC can only use one WAN port, and it does not have the effect of bandwidth superposition, which wastes the bandwidth of multiple lines. Strictly speaking, IP balancing is equivalent to the superposition of two or more single WAN products.

The true bandwidth aggregation effect is accomplished by a load balancing function called SESSION in the router. The real bandwidth convergence router is designed with SESSION as the unit, and sends the Internet access requests sent by the PC to different WAN ports according to the busy and busy levels. When the Internet data comes back, it can also return through different WAN ports. And each PC can send dozens or hundreds of SESSIONs at the same time. In this way, when opening web browsing, downloading and other operations, because these SESSIONs can be assigned to different WAN ports, the PCs do not have to be on an external line one by one. Send SESSION and wait for return, but can send SESSION on several WAN ports at the same time, and return data on several WAN ports respectively. As a result, this PC has achieved the purpose of using multiple lines to access the Internet, and doubled the bandwidth.

Some "fake multi-WAN" routers are still deceptive, that is, the router will use the "IP balancing" fake multi-WAN processing method, but there are also true multi-WAN function options for session balancing. Due to the immature true multi-WAN session processing method, there may be application exceptions such as QQ disconnection, bubble club games cannot be played, etc. In the end, such routers also recommend that you use IP balancing to avoid technical shortcomings. This makes Session mode useless and cannot be used normally.

Xinxiang multi-WAN routers have upgraded the multi-WAN technology to the fourth generation and integrated the most advanced "identity binding" technology, which is an absolute leading advantage in the industry. Here we would like to remind you to pay attention to check when purchasing multi-WAN routers Is there an IP balancing option in the router? Be careful not to buy fake multi-WAN routers, accurately determine multi-WAN application strategies, and make multi-WAN technology truly serve your network.
