We will learn about subnets and CIDR (classless Inter-Domain Routing. We hope to learn this knowledge more easily than some books provide.Let's first figure out one thing: there is no "category" in the subnet. In the past, networks were divided into

With the development and application of VoIP, VoIP has attracted more attention from hackers, network scammers, and spam email makers. As a result, the security of VoIP has become increasingly prominent. Typical VoIP Security problems include: ·

Most home users use the ADSL dial-up method to surf the Internet. However, in this environment, once we activate the eMule or BT application, these applications tend to "Occupy" all limited ADSL bandwidth resources without hesitation, so that other

1. Overview The Internet has become an important part of information infrastructure in modern society. It plays an important role in the development of national economy and social progress. It has also become an important supporting environment for

For IPv6 translation, the new saying is: "The Dual stack can be used where the dual stack can be used, and the tunnel is used where the tunnel has to be used ." Users are concerned about how to migrate data from IPv4 to IPv6. In the current

IPv6 solves the shortage of IP addresses first. Secondly, it makes major changes to many imperfections in the IPv4 protocol. The most significant one is to integrate IPSecIPSecurity) into the Protocol. From then on, IPSec does not exist

Compared with IPv4, IPv6 has many advantages. First, IPv6 solves the shortage of IP addresses. Secondly, IPv6 greatly improves many imperfections in the IPv4 protocol. The most significant one is to integrate IPSec into the Protocol. From then on,

My old friend xiaohou successfully ranked among the "white-collar" after graduation. This public network is like life, and soon I bought a kind. Whether at home, at work, or at Starbucks, he always takes the time to open his laptop and find wireless

It can be said that the prosperity of the wireless connection era is inseparable from the contribution of the Bluetooth Technology Alliance SIG, this organization is primarily responsible for ensuring that hundreds of millions of Bluetooth devices

For many consumers, wireless technology is good and convenient, but if BT cannot be downloaded and the game cannot be smoothly played, then it has no value. The focus of this article is to introduce how to make reasonable BT download settings in the

You can learn network access control solutions in a few minutes. IP address connection, local connection will also be mentioned in this article. Recently, there have been many disputes over what constitutes a "complete" network access control

Integration of access networks: cost-effective transmission of devices; Integration of access networks is a common problem. But how can we set more precise integration of access networks to facilitate our use? To adapt to the fierce competition in

There are many things worth learning about the optical fiber access network. Here we will mainly introduce notes on emerging technologies of optical fiber access networks. At present, the world's optical fiber copper withdrawal has become a trend in

VDSL technology has become a new favorite of line access technology. When you search for the keyword of VDSL technology, it is to understand VDSL technology and become a problem of line access technology. Therefore, this article should be able to

4) In housfe-series video panelThe In HouseTM series video panel allows you to easily integrate cable TV, satellite TV, security, and other systems throughout the home. The video panel is integrated with PCB technology, which improves the operation

In a two-way cable TV system, to make reverse transmission work normally, the confluence noise must be reduced. Most of the confluence noise is formed by a space electromagnetic interference string into the reverse system. In a Bidirectional CATV

Structured Cabling System Design PrinciplesPracticality-the communication cabling system to be implemented will not only adapt to the continuous development of technology, but also realize the transmission of data communication, voice communication,

With the extensive laying and use of optical fiber lines, the reliability and security of optical fiber communication systems have attracted more and more attention. Due to the vast territory of China, the terrain and landform are quite different,

Most of the integrated cable systems are installed using traditional optical fiber systems. In this case, appropriate Optical Fiber installation should be carried out using the discussed design methods. The system has proved to be feasible, reliable,

The Phase I Project of Shanghai zizhu Science Park covers an area of about 13 square kilometers. As the core project of Phase I project, science Plaza has been constructed and some floors have been put into use. It covers an area of about 167 Mu and
