4-7-layer Switch marry

Mention of the 4-7-tier switch users, the industry often think of ICP and ISP, but from 2003 onwards, the 4-7-tier switch user structure has begun to change, some enterprise users began to use such products. The 4-7-tier switch is a trend to marry.

Security issues to marry him

Many enterprise users from 03 began to pay attention to the 4-7-tier switch, a very important reason is the network security problems of enterprises. The problem of information security makes the name of "Global Village" more and more image, with the increasing popularity of the network, a new virus in a very short period of time can be in the global scope. The previous cycle of computer viruses that spread through storage media is two months old and now takes two days with the help of web pages and emails. The most powerful virus in the 03-shockwave, which spread over a 8.5-second span, has been raging around the world in just 3 hours.

Compared with previous years, 03 is the most information security accident in China, the widest range of the year, network worms are the root cause of these accidents. The January SQL Killer caused more than 20,000 database servers in China to be affected, and the international export of a backbone network was nearly paralyzed; the March red Code worm's F variant spread to the Internet as much as 10多万次; the August shockwave and Sobig virus have so far been in the network, The affected host is already close to more than 2 million units. So many viruses make network administrators tired, but the loss is unavoidable.

During the peak of the virus outbreak, some enterprise users suffered a small loss, even without any impact. Many information security vendors have analyzed this phenomenon and found that these users of the virus prevention strategy properly, the rapid response is the root cause of the small loss. "Quick response" has become one of the most effective tools for users to prevent viruses and avoid losses.

The 4-7-layer switch greatly increases the response speed of the user as a worm-like virus attacks. In the case of a radware 4-7-tier switching device, the product's security module, within 24 hours of discovering a virus attack, can provide a complete solution for the characteristics of the virus attack and protect all of its internal network devices and hosts through a 4-7-tier switch. Because the 4-7 layer switch is based on the hardware Exchange architecture, is not related to the server, the operating system, has overcome some information security software cannot cross the operating system the fatal flaw, receives the user's welcome.

According to the findings of the Market Research Institute, this is also proved. The results show that over the past 6-12 months, a variety of virus attacks have occurred frequently, and more and more enterprises integrate web-based services into the daily workflow, which makes application and content management more important, resulting in a significant improvement in the market of the 4-7-tier switch since the dotcom bust.

In fact, the 4-7-tier switching device is not only used to prevent computer viruses, but also the protection of other information security is very obvious. As F5 company China Sales Manager Mr. Wu Josong, said: "4-7-tier switch on the network security of a lot of, not only in the virus prevention, but also to share the firewall, IDS (intrusion detection equipment) to withstand the flow of pressure, while the network transmission data, 3A authentication as well as code encryption and so on will have a great role. ”

Intelligent load balancing helps to promote it

4-7-tier switches are welcomed by enterprise users The main reason is the Intelligent load balancing function, this function can better solve the enterprise network frequently encountered problems. These problems can be roughly divided into two categories, one is the security problem mentioned above, the other is the network traffic pressure problem.

At present, the competition in various industries is becoming more and more, and the improvement of informatization is one of the effective means for enterprises to develop and enhance their competitiveness, so enterprises with certain strength have put ERP, CRM and other projects as the focal point of information construction in the unit. Whether ERP or CRM, are developed on the database platform, so compared with the past, for users, the database is more and more gold.

A customer to an enterprise through the Internet to order or query the relevant information and eventually display results, this is very common for any enterprise. And it's just such an ordinary visit, the required process is extremely complex, especially for a huge database of users.

This process includes the customer input related instruction, the front-end software passes the customer instruction to the middleware software processing, the middleware software according to the user's instruction, carries on the query to the database related data to inquire or appends, modifies, deletes and so on the operation, and displays the final result. Because databases are installed on multiple servers, each server needs to receive data from other servers throughout the process, as well as generate a large amount of intermediate data. The resulting large amount of intermediate data will directly consume the server resources, and due to the impact of the server throughput limit, the efficiency of the whole network system will be low and the system bottleneck will be formed. It is one of the most effective ways to break the bottleneck by using the Intelligent load balancing function of 4-7-layer switch. According to statistics, "query" accounts for 90% of the total of all operations performed by the user on the database. When the system is added to the 4-7-tier device, the user's operation instruction can be judged, and the effective principle is decomposed into several servers to accomplish together, thus improving the overall efficiency of the system.

According to F5 company Wu Josong introduced, the company a financial industry users in the original network of equipment used in the computer has a minicomputer also has a PC server, the network availability of 99.5%, in the use of 4-7-tier switching devices, the network availability rose to 99.999%. It seems to be a small change, but it's amazing how money is measured (see table). This user system every 1 hours, will suffer the loss of 50~70 million, the annual loss due to downtime is about 1% of the original. This shows that the reduction of operating costs is the 4-7-tier switch to attract users the most fundamental reason.

It is certainly good news that users are interested in 4-7-tier switches, especially those with 2~3-tier content-exchange devices like Cisco, which can sell 4-7-tier products directly to the existing user base. But there is no denying that in China's 4-7-tier switch market mature still a long way to go, manufacturers, channels must pay more efforts to educate the market. And the 4-7-tier market is only a small piece of the network market, it may be the manufacturer and channel a new profit growth, but it is impossible to replace other network products.
