IPv4 is an indelible network, but it cannot meet our needs as we need wireless networks. Now it is about to quit dance, instead of IPv6. However, based on Internet operation experience over the years, we should make some "revolutionary" changes to

More than 40 countries around the world have carried out 100 PLC connected lab projects to ensure the feasibility of PLC Technology and commercialization. In order to expand the Power Line Communication Market, current research hotspots focus on the

NGN has become one of the mainstream technologies for voice and video communication. The R5 phase of the 3G standard will also be a service platform with NGN as the core network, and the application of IPv6 will play a role in promoting the

Snmp mib is a major module of SNMP protocol software. Therefore, the main function of MIB is the Management Information Library, we have also discussed some of the previous articles, but many of our friends still do not understand snmp mib. For this

We know the excellent performance of IPV6 network protocol, and the most widely known is that it solves the problem of address resource depletion. However, it has other advantages in many ways. The following describes the security of IPV6 network

After introducing the HART protocol physical layer and the HART data link layer, we also elaborate on the HART service. Through these series of explanations, I believe everyone has a certain understanding of the HART Protocol application in the

It is very convenient for Telnet programs. I can remotely manipulate the application of this program. Here we will mainly explain how to use Telnet to export and import the Forum mysql database. The application is summarized as follows: 1. The

Many friends have asked how to change the Telnet port number. In fact, we have referred to Microsoft's materials for this question. Let's take a look at the specific change measures. I hope you can use this article to master this part of

Telnet commands can be typed by DOS, so these commands are easy to use. Here we will introduce several common commands. There are many commands in the telnet program. You can enter telnet or ^] on the keyboard to enter the special command status. At

For wireless data networks, voice is a "killer application ". The high-performance Wi-Fi mesh network system is a killer IP wireless network. However, not all mesh networks are identical. As wireless mesh networks become increasingly popular-almost

If we consider deployment as a process of network transplantation, deploying a wireless network on the original wired network is actually a kind of wireless grafting. From the biological point of view, to achieve a successful grafting, in addition

1 Overview At present, after completing the network transmission infrastructure construction, China's major communication operators have made full use of the bandwidth of the existing transmission link and sought new value-added communication

Brief history of Optical Fibers As early as 1841, Daniel Colladon of Switzerland first elaborated on the idea of transmitting a beam through a water jet. Then, through a beam in the water flow across the table, he realized light propagation in the

Parallel Optical Interconnection Technology Along with the digitization process, data processing, storage and transmission have developed rapidly. High bandwidth makes short-distance Interconnection a bottleneck for system development. Due to

There are still many things worth learning about in the cat6 cabling system, especially in the actual construction phase. To avoid these problems, we should make sufficient preparations before construction, in particular, pay more attention to

The energy-saving effect of the frequency conversion device is very obvious. The variable-frequency speed control motor is used in the high-power motor, and the entire generator set can save energy by 30%. After variable-frequency speed control is

It is recommended that enterprises consider the following five issues before switching to VoIP: 1. Is your network wiring qualified? The level of enterprise internal network cabling is very important. We recommend that you use a CAT-5e (100 M) or

A sound video transmission design is a very important part of the CCTV system. If a set of built systems choose cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but there is no good transmission system,

Distributed design in data centers In a typical distributed switching architecture design, each server cabinet is connected through copper cables or optical fiber cables. For copper cabling, most cabinets in the data center are connected through

The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling
