A frequently asked question in the network class is, "Why don't we place all the devices in the same subnet? This eliminates the need to worry about routing issues ." The reason is simple. Each time a system needs to communicate, whether it is a

TCP is used everywhere. Understanding the working principles of TCP helps administrators correctly diagnose network communication faults.The TCP protocol is complex. But don't worry. We didn't ask you to read RFC 793. This is just an initial lecture.

During the transition from a mobile network to a mobile IPv6 network, IPv4 networks and services will coexist with IPv6 for a long time, and many services still need to run on IPv4 networks for a long time, in particular, IPv6 cannot provide global

Along with the gradual expansion of the LAN scale, a network is often divided into multiple different subnets, so as to meet the work requirements of different subnets to achieve personalized management requirements. A large LAN usually uses DHCP

I. Introduction With the rapid development of network technology and wireless communication devices, people are eager to obtain information from the Internet anytime and anywhere. In response to this situation, the Internet Engineering Task Force

We have said that the Internet is a large inter-network that connects countless networks around the world. Computers in each network are uniquely identified by their own IP addresses. Therefore, we can imagine that, on the INTERNET, each network

Recently, after we forcibly uninstall the Norton Anti-virus software installed on Windows XP, we find that the laptop suddenly cannot access the Internet. when we open the neighborhood attribute window and check the properties of the local

With the development of information technology, remote access networks will also develop towards virtualization. Virtualization has a profound impact on the access network industry. How to Apply virtualization technology in the access network field

In the development of broadband access networks, the application of Beijing Netcom ADSL has become very popular. So I have studied the characteristics of broadband access networks and some solutions. I will share them with you here, I hope it will

With the development of the access network technology, its related devices are also widely used in various fields, and there are also many problems, especially some problems such as ARP attacks, next we mainly analyze the solution to the access

Users of the access network have encountered many problems or faults. Here we will introduce the solutions to common problems of ADSL access network faults. The application of the ADSL access technology greatly increases the user's Internet access

Users who use ADSL access network devices have encountered many problems, especially some network faults, which are a headache. Generally, users do not know what the problem is. The ADSL access network device has a CD or Link indicator. Normally,

The Administrator solves network security threats of different enterprises. For many friends, the network security threats of enterprises are still a common topic. What does it do? What is its role? Let's take a look at these questions. From the

I have introduced the basic knowledge and security of wireless networks in the previous articles. This article describes the security of wireless networks. This article analyzes the location of wireless devices and the interference of wireless

ADSL is a very common broadband access method. However, since one user has only one ADSL account, how can we achieve multi-user sharing of ADSL? Here we will introduce the implementation method. ADSL is an affordable broadband access solution.

If you want to use an account to connect to the network as a proxy, we will introduce the method of using the route function to describe the ADSL proxy settings. Multi-host sharing of an ADSL Broadband line has become the most popular topic on BBS

In FTTx development, the access layer needs to create a huge optical fiber distribution network, that is, the ODN network. The cost of building the ODN network is high. The maximum investment can be 50%-70% of the total investment, which is the
