Talking about the issue of north-south interoperability and talking about multiple WAN broadband routers

China's broadband Internet is indeed unique, and it is also strange and mysterious. In this specific network environment, some different and extraordinary network devices have been derived, which are exactly the multi-WAN port broadband routers to be discussed in this article.

North-South Interconnection Issues

Since May 2002, the former China Telecom Group was divided into north and south regions, and the new China Telecom and Netcom Group were established. The backbone network of the Internet was divided into two parts. The north was managed by Netcom Group and the south was managed by China Telecom. Therefore, there are problems with the interconnection between Telecom and Netcom. The access between Netcom and Telecom is very slow and even inaccessible.

If China is vast and vast, I believe no one will deny it. Indeed, China is really big, so big that it is necessary to build two different and not very connected networks. Isn’t it ridiculous? Think about it, if China also built two different transportation networks, such as trains, railways and shipping, would it be very novel? From Guangzhou to Beijing, to Henan Province, please get off the train and walk to another train station opposite to continue the train to Beijing. I believe everyone will be dizzy. Why is China's Internet like this? Is there any "problem" potential?

This problem has always plagued the north-south communication of enterprises, and the hardships have made these small netizens who need to travel from the south. With interests in the forefront, everyone holds the "sharp" sword, and no one is willing to let go of their interests, let alone reciprocal cooperation. Under this network situation, let alone VOIP? IPTV? The Internet has not reached a unified state for a day, so these false talks will never be realized. Do you have to give up the Internet world for the sake of the interests of an individual and a certain company?

The so-called "the top has policies and the bottom has countermeasures."

In this network environment, many good strategies have been derived, such as IDC service providers adopt telecom and network connection dual-line approach to solve problems such as slow speed. Some broadband routers have also emerged, and multiple WAN port access solutions can be introduced, which can access telecom and network communication lines respectively, so as to use different broadband lines to access the corresponding local servers or websites.

Multi-WAN router

The emergence of multi-WAN has not been a year or two. Multi-WAN technology originated from Europe and the United States. After entering the Chinese market, there are many differences in functions and applications. Multi-WAN has many practical functions, such as line backup, bandwidth expansion and multi-ISP access, which are not possible in a single WAN.

Here are the features:

Bandwidth expansion: Different broadband access can be increased according to the usage environment and the number of users, thereby effectively saving costs. The cost of optical fiber in the domestic broadband market is much more expensive than ADSL. By using multiple WANs to access multiple ADSL lines, it can not only meet the needs of broadband, but also effectively save broadband expenses. In addition, when new devices on the network are added, the broadband usage load exceeds the broadband usage load, and another broadband can be connected.

Connecting to multiple ISPs: This is the feature of China's multi-WAN routers. Since cross-network bandwidth between different Chinese operators is limited, the bandwidth of many cross-networks will become very small, such as slower playing online games and unsmooth watching movies. Multi-WAN routers can connect to different operators and set policy routing to automatically forward, without being restricted by cross-network, which can solve problems such as slow speed caused by cross-network.

Bandwidth backup: Due to the unstable bandwidth connection, some areas will be disconnected 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.

Bandwidth management: Many WAN routers nowadays already have these functions, allocating different or many broadband resources according to different users or environments, so that broadband can be used more effectively and rationally. For example, Internet cafes are divided by region. On one hand, there are users who chat and browse the Internet, and on the other hand, there are users who need to download or play online games, so broadband resources can be allocated proportionally. For example, within an enterprise, a certain department needs to transmit network data, a certain department only needs to send and receive emails, and so on.

There are many brands of multi-WAN interface routers in China, why are there so many? It's all because of the private label. In fact, there are not many WAN brands operating in China, and the products mainly come from *, because the * manufacturer brands did not directly enter the mainland market in the early stages. Some merchants seized the opportunity, bought products in batches, and then thought of a brand and made a packaging themselves, and became a brand new brand.

This kind of unsuccessful small fight has continued to happen again and again. This undoubtedly affects the development of multiple WANs. After all, small companies lack technical strength and will lose their business if they cannot continue. This has a significant impact on the majority of users and they lose confidence in using it. The author once saw two different brands and models in an IT market, and the prices were different, but paying attention to it, it turned out that the inside was the same. Just because your OEM price can be regulated at will, you can get over the manufacturer's addiction. The price positioning depends on the quality of the packaging design and the strength of the market promotion. This will undoubtedly make users feel confused and at a loss.

Nowadays, there are only a few mainstream WAN brands in the market, including Xinxiang, Xianuo, Aitai, Feiyuxing, etc., and of course, there are many homemade brands. Since the application of multi-WAN has great market opportunities in China, several well-known network brands have also intervened in recent years, such as TP-LINK, Zhongyi Digital Kuan, SMC, Jinlang, etc.

Because the development of multi-WAN technology in China is special, and the mechanism of multi-WAN technology has not been formulated with international standards and the technology is not perfect, the core technologies and algorithms between brands are self-consistent. In addition, multi-WAN technology has not been recognized by major brands such as Cisco and Huawei, so it will be difficult to develop.

Multi-WAN technology is in a "chaotic era" period, which requires the emergence of "heroes". Troubled times are also a great time to fish in troubled times. It is precisely because of these fishing people that many WAN technologies are covered with shadow. However, what is certain is that the Chinese market needs more WAN technology, and if there is demand, there will be business opportunities. Multi-WAN technology still needs these manufacturers to create a newer field. Multi-WAN manufacturers, work hard!
