With the popularization of Internet broadband access services, broadband applications are becoming more and more deeply involved in the work and life of ordinary people. The serious enterprise applications in the past have also entered the stage of broadband interconnection through the Internet. With the development of various applications, broadband routers must keep pace with the times to meet the needs of various new applications.
Multi-WAN broadband access routers are generated when the application requires them. In fact, multi-WAN broadband access routers originate from advanced European and American countries. The main application is to assist enterprises in flexible use of bandwidth, especially in a telecommunications liberalized environment, which can connect different operators to enjoy different discounts. At the same time, multi-WAN routers can also effectively increase bandwidth, in response to the increase in broadband applications and the increase in the number of people.
Multi-WAN router application features in China
However, after the multi-WAN broadband router entered China, the market development of the market is somewhat different from that of European and American countries. According to Qno Xianuo's experience in different countries, multi-WAN routers have the following characteristics for application in China:
Bandwidth expansion:The first batch of applications of multi-WAN routers in China took place in Internet cafes and communities. Since it must respond to many users, increasing bandwidth through multi-WAN routers has become the most direct choice. In addition, some users find that the functions of multi-WAN routers can connect multiple ADSLs to replace optical fibers. Since the bandwidth cost of optical fibers is much higher than that of ADSL, bandwidth cost can also be saved.
evenConnect to multiple ISPs:This is a feature of China's multi-WAN router applications, and it is not available in Europe and the United States. Since cross-network bandwidth among different operators in China is limited, the bandwidth of many cross-networks will become very small, such as slower online games and unsmooth watching movies. Multi-WAN routers can connect to different operators and set policy routing to automatically forward without cross-network restrictions.
Bandwidth backup:Due to the unstable bandwidth connection, some areas will be disconnected once every few days. When broadband online plays an important role in corporate operations, disconnection often means work interruption, service interruption, and money loss. Multi-WAN routers can provide backup functions, and even if one WAN is disconnected, it can be connected from another WAN end, which can maintain the stability of broadband access.
Growth elasticity:QnoSundo WAN router has built-in bandwidth management function. Network management can set different applications to different WAN ends according to bandwidth application requirements, such as image conferences are left to specific WAN ends to ensure online quality. When users or applications grow in the future, different WAN ports can be enabled one by one to expand bandwidth.
Multi-WAN VPN application features
After understanding the application characteristics of multi-WAN routers, let’s look at the application characteristics of multi-WAN VPN routers. Since this product is based on a multi-WAN VPN router, the aforementioned functions are available in multi-WAN VPN routers, and the following application features can also be provided.
Solve cross-network problems:The problem of insufficient cross-network bandwidth still occurs in enterprise VPNs. We often hear in various places that the headquarters is surfing the Internet through telecommunications lines, but the branches use Netcom to access the Internet. The VPN is very unstable, and even if the online connection is successful, the bandwidth is very small. Multi-WAN routers can help solve this problem. Multi-WAN routers can be installed at the headquarters or branch, and then choose to use the same operator line to establish a VPN, which can solve this problem.
VPN backup:The purpose of enterprises to build VPNs is to hope that confidential data can be transmitted safely on the network and to use Internet-friendly communication channels. However, once the line is disconnected, no matter how strong the VPN protocol is, it will not work. Therefore, the VPN backup function can re-establish VPN connection from other WAN ports to reduce the impact of disconnection. It is even more important for enterprise applications that focus on timely information transmission.
Elastic application:Some enterprise network administrators hope to separate the bandwidth of ordinary users' Internet access from the bandwidth of VPNs to reduce the impact of VPN connections. At this time, the VPN bandwidth can be skillfully set to a specific WAN terminal, and other applications are set to other ports, so that the VPN bandwidth is not affected. Especially there are a large number of document download requirements, which requires this situation.
Expand VPN bandwidth:Xianuo often encounters ERP or financial software in various parts of China. During regular transmission, due to the large transmission content, the response speed of a VPN transmission is too slow. Establishing a VPN with multiple WAN terminals can increase the bandwidth of the VPN to solve the above problems.
The above functions are all things that traditional single WAN VPN cannot do. Therefore, we see that in the international market, when choosing VPN products, small and medium-sized enterprises generally use multi-WAN VPN products as their preferred choice because they can solve the actual problems of the enterprise.
