What is a high bandwidth server ? What is the reason for the large bandwidth server network freeze?
I'm Ai Xi, and many people have asked me a question recently: Why does my server freeze even though I'm using a server with a large bandwidth? The first reaction of many people is that the server is poisoned? The server was attacked? Today, Aixi will talk to you about several reasons that may cause large bandwidth servers to freeze
What is a high bandwidth server?
Before mentioning large bandwidth, first understand what bandwidth is. Bandwidth is different from what we call broadband at home. Broadband can be simply understood as a service that operators connect to the Internet according to family or business needs, and bandwidth is the transmission speed (uplink ).
What we call a high-bandwidth server is a general term. Generally speaking, a bandwidth of more than 100 Mbps can be called a high-bandwidth server, and a server using this bandwidth can be called a high-bandwidth server. The servers used by large bandwidth generally support automatic switching between 100Mbps and 1000Mbps network cards.
Advantages of large bandwidth server:
1. Large bandwidth server can reduce the loading speed of the website
The main function of large bandwidth is to realize the synchronous transmission of two-way data. It improves the speed of data transmission while ensuring stability. Therefore, the use of large bandwidth can make the website have a faster access speed and enhance the experience of users browsing the website. .
2. A large bandwidth server can make the website run more stably
During the peak period of website access, if there is not enough bandwidth supply, it will cause the website to freeze, the access speed is slow, the image quality is not clear and other bad phenomena will occur, and even the server system resources will crash and the website will be paralyzed. The large bandwidth server can effectively avoid some interference, deal with the corresponding problems in time and block some network attacks. Therefore, if you want to pursue fast access and stability of the website, you can choose to use large bandwidth.
3. Large bandwidth server can increase the defense performance of the website
At present, network attacks are still dominated by traffic attacks. If you use a large bandwidth server, because of the large bandwidth channel, network attacks cannot easily achieve the purpose of occupying the bandwidth channel, which also prevents the occurrence of general network attacks, thereby ensuring the normal operation of the server. run.
4. The large bandwidth server can meet the needs of building a remote website
The current website content is mainly video, music, and pictures, and the quantity is huge, so it consumes a lot of bandwidth and traffic resources. Renting a large bandwidth is a very good choice for this type of website, which can provide a faster and safer website access environment. .
So our topic today is that large bandwidth servers will freeze?
There are many reasons for the server to freeze, generally divided into the following points:
1. Network problem
First check whether the local network is normal, and ping the test server to check the delay. If there is packet loss, etc., but the other server does not, then there is a problem with the server. If many users report cards, it is necessary to determine whether there is a problem with the large server network.
2. Server poisoning
If the server is poisoned, it will cause the server to send packets to the outside world, exhausting the bandwidth and causing lag. It is recommended to perform antivirus first to clean up suspicious files.
3. Attacked by CC
The attacker controls some hosts to send a large number of requests to the target victim server, thereby achieving the purpose of consuming server resources. The more connections, the greater the resources occupied, which will cause network congestion. In this case, it is recommended to contact the service provider to adjust the strategy immediately.
4. Full bandwidth
If the bandwidth is too high and the line is congested, the data transmission will become slow, and the bandwidth can be upgraded. However, the price of additional bandwidth is relatively high. If there is more bandwidth than the server package itself, it is recommended to separate it if it can be separated.
5. Insufficient configuration resources
As we all know, when renting a high-bandwidth server, it will involve the selection of configuration resources such as the server's CPU, memory, hard disk, and bandwidth. When the CPU cores of the large-bandwidth server are insufficient, the information processing will be slow; the network bandwidth star is not enough to support the access of the big-star customers, and the access speed will also slow down. These are all due to insufficient configuration resources of the large-bandwidth server, resulting in configuration problems, which eventually lead to a slowdown of the large-bandwidth server.
6. Software problems
Errors in software operation and system errors will also cause the server to freeze.
Warm reminder: During daily operation, do a good job of server maintenance and backup to reduce the chance of failure.
7. The link to the IDC information center is unstable
In addition to accessing the bandwidth of some formal IDC information centers from the backbone network, some IDC information centers will also use other cable methods to access the IDC information center, resulting in the disadvantage of fast and unstable bandwidth at the source of bandwidth. Customers may encounter bandwidth instability during use, resulting in bandwidth problems in large-bandwidth networks, which is also one of the factors that cause customer access speeds to be too slow and delayed.
8. Customer's own network environment problems
Another factor is that the visitor's own network bandwidth is insufficient. When the customer opens the network bandwidth, the bandwidth capacity will be different. When the bandwidth is low, no matter what page they visit, there will be a noticeable delay.
There is also a problem of network lag caused by regional factors: For specific link factors of the executor, you can check it yourself
I'm Ai Xi, the above is the reason why the network card of the high-bandwidth server is unstable. That's all for today's sharing. I hope it will be helpful to friends in need.
