Network infrastructure ( ), in layman's terms, is the sum of the software and hardware facilities that build network systems. It is a major cornerstone of the stable operation of the network. For example, if you want to access the Internet and connect all devices together, it all depends on this network infrastructure! Without it, no one can imagine that mobile phones or computers can be connected to the office.
Hardware components
1. Server : This is a key role in data processing and storage in the network. The company engages in websites and stores business data, and it depends on server support. Servers like Alibaba Cloud are particularly stable and efficient, and the daily operations of enterprises rely entirely on them. Enterprises of different sizes must select servers based on their own data capacity requirements and access frequency. Small and medium-sized enterprises just need to have a small server; large enterprises have to pile up several large servers to meet business requirements, but they are not careless at all.
2. Switch : It is like a courier, ensuring that data is properly transmitted from this device to that device. When working, forward data frames according to the MAC address. In the enterprise LAN, many devices are connected by switches. It is enough to use small Layer 2 switches in the home to communicate; enterprises need large Layer 3 switches to make LAN connections to ensure smooth communication.
3. Router : The router plays a major role in connecting different network segments. A home router connects the home devices to a broadband network, and it depends entirely on it for family members to use computers and mobile phones to access the Internet. The router functions used by enterprises are even more powerful. Not only do you need to connect the internal LAN to the external network Network Infrastructure, but you also need to ensure the absolute security of the network and set multiple routing rules. For example, Cisco's enterprise-level router is quite powerful, providing all-round traffic control and stability, and firmly acting as the "guardian of the network"!
Software configuration
The network operating system can make the entire network run well. The system is widely used in small and medium-sized enterprises, and it has a variety of functions and is more convenient to operate; Linux system has become famous for its open source and stability, and this is commonly used by large enterprises. Firewall software and intrusion detection systems are crucial to ensure network security. Firewalls intercept illegal traffic; intrusion detection systems like Snort monitor whether there are bad people attacking. Provide global procurement services for weak current intelligent products!
By rationally configuring servers and switch components, an efficient, safe and easy-to-use network is built. Daily maintenance should be paid attention to, such as servers and switches, and router rules should be sorted out every once in a while. By doing so, the network will run stably, powerfully and efficiently for a long time.
Common Q&A
Q: The home network environment is simpler. Don’t you need to pay too much attention to the configuration of these devices?
A: Although the requirements for home configuration are not that high, it has to be particular. Low-quality routers will often be disconnected from the Internet and stuttered. Reasonable placement and the use of branded and reputable equipment can make the home network stable.
Q: How can a large enterprise restore normality as soon as possible if there is a problem with the network of the network?
A: Network emergency filing can be pre-set and regular drills can be practiced. Servers and data are also regularly backed up. As soon as you see the problem, you immediately switch to the backup device to maintain key business operations.
In my opinion, as technology moves forward at a rocket-like speed, the complexity of the network will increase. From now on, steadily configure and manage network infrastructure equipment will benefit enterprises and individuals without any harm. We must actively keep up with the times and let the equipment and network play the best role!
