Nowadays, installing broadband, setting up routers, and sharing wifi is not a very difficult task at home. With the reduction of operator tariffs and the competition between each other, homes with 2 or more broadband are now installed. Not a few. However, the question is: How do you use the best or most efficient method once you have 2 or more broadband? For example, the author's home was originally equipped with a broadband of China Telecom. Recently, China Mobile has used the author several times to call for free installation of a broadband for a year. After receiving the third phone call, I was embarrassed and resigned to agree. The efficiency of the move can also be, immediately after the appointment of an appointment to send people to open the light path, the data is ready. Initial test, the bandwidth is about 10M, it is OK, after all, is sent, the request can not be too high. Although in the field of home broadband, telecommunications is always the oldest and the investment is also the most, but the construction of mobile broadband in the past two years is still possible. Many common applications, the portal has introduced mobile line access, previously mobile broadband So slow because of the problem of cross-operators, now using mobile broadband to access some resources, the speed is not slower than telecommunications (here seems to be advertising for mobile, and who told people to use soft hands ^ _ ^).
After the broadband is installed, then the problem has come. The original home of the author used a millet router to make use of it. We cannot always connect telecommunication when we want to use telecommunication and want to connect mobile when we move. Now that the electric business is so developed, immediately go to the Internet to search for a dual-WAN router. In general, home routers have only one WAN port, popular point is that there is only one port can access broadband, other ports are used to access the home LAN, dual wan port router may use a little more at the enterprise level. What did you search in Jingdong? The most common way is so cheap. I thought it would take a lot of money to implement the functions that the author wanted to realize. I didn't need to pay much for it. Ever since, bought a 200 "enterprise-level" routing (please don't despise the author, only 200 pieces anyway, can not afford to lose, can not buy fooled, it can not I use it as a backup route Ye Hao, as a wireless AP also ah ). Now that logistics is available, orders are placed in the morning and received in the afternoon. The new route took home, opened a light, on the power, all normal, entered the common configuration page of the public.
With the regular wifi, lan, dhcp and so on, because the new route defaults to only one WAN port, other ports are multiplexed with wan and lan, so you need to set the port mode to dual wan port, after the setting is complete, the next step is Configure the WAN port. According to the link connection, the wan1 port is connected to the mobile port, the wan2 port is connected to the telecom network, and the mobile Internet access method is to automatically obtain the ip address. The telecom service provider needs to set the pppoe dial-up Internet access. After setting up the connection test is not connected, if connected, that wan port configuration is complete.
With the wan port, which is the broadband exit, there will be a problem. When I use the router to access the Internet, do I use the Internet to access the Internet or telecommunications? Or is it moving for a while, what about telecommunications? Did a bit of tracking, found that the current router environment, no matter what website or application I visit, the default is to go from wan1, which is the mobile broadband line to access the Internet, then my telecommunications line is not useless? This requires a function called "traffic equalization" in the router. At the same time, in order to ensure the efficiency of accessing different websites accessed by different operators, the ISP routing function is enabled in the ISP route selection. In this way, when we visit the telecommunication web site, we will give priority to the telecommunication line. When we visit the mobile web site, we will go mobile. The line avoids the data delay caused by the operator. To give a simple example, in the case of only one broadband, when playing online games, you need to enter different servers according to the broadband conditions of your home, such as a telecommunications area, a mobile area, etc. If your home is broadband for telecommunications, you have to If you play games in the mobile area, you will find that the cards are going to die. . . Do you say yes? Now that we have set up the ISP routing function, whether it is in the telecommunication area or the mobile area, we should not feel the card if we have enough bandwidth. In addition, we set up line backup, and maintain the main and backup ports in it. In this way, in the case of a broken broadband connection, the other one can still work normally. This is for some stocks that are worth hundreds of thousands of shares a minute. For a user who is not able to disconnect the network at a critical time, it is a more practical function.
Do a good job of configuration, that is, a simple test, we can find a mobile, a telecom IP look at the routing of the visit, here I take the two operators as the destination address of the DNS address trace, you can see, Access to the mobile address takes the mobile line out, and the access to the telecommunication address goes out on the telecommunication line. As shown below:
Well, to say so much, can only be said to be an introduction, the validity and stability of some functions have yet to be further tested, such as the router built-in isp database is incomplete, new is not new? In the end load balancing can be more balanced? But at least now basically achieve the following functions:
1. Line load balancing. When a broadband line is busy, newly initiated calls may switch to another broadband line. 2. ISP automatically selects routes to reduce cross-operator delays. 3, line hot standby to prevent disconnection.
