Bkjia.com April 27 Internet headlines: How do we know when IPv4 address space will be used up? What will happen when that day arrives? Who can answer these two questions? The Internet we are using is built on IPv4. According to the definition of IPv4

When IPv6 was launched, many people thought it was unnecessary. However, with the increasing superiority of IPv6 protocol applications, many organizations have begun to build IPv6 networks. Now we will introduce the construction of IPv6 in the data

Vrouters and vswitches are the core hubs of our network. The changes from IPv4 to IPv6 will surely change in the current network protocol. Now we will introduce you to a vswitch product, a high-end multi-service IPv6 core route switch. This series

In traditional IPv4 networks, security has always been a headache. Now the IPv6 protocol network has solved many security problems for us. This is because, in the IPv4 network, the evolved version V6 adopts different transmission structures, so the

With the rapid development of wireless technology, home wireless networks have grown from 11 Mbps of 802.11b to 54 Mbps of 802.11g, even more, many individual users who have special requirements on wireless coverage and transmission speed use more

A few days ago, Trapeze Network for Trapeze NonStop Wireless™The SmartPass 7.0 access management platform is launched for network products. SmartPass 7.0 helps network administrators precisely control all aspects of access management, including

With the acceleration of modern technology, each department of some large and medium-sized enterprises is equipped with computers, and some are even more than one. To facilitate data transmission and speed up work efficiency, enterprises have set up

Based on the needs of network convergence, from a technical perspective, 3G/PHS network convergence is feasible. Background of PHS and 3G network convergence As an important source of income for fixed-line Chinese telecom operators, PHS has

Traditional wired network management methods and technologies can be easily transferred to wireless networks when special wireless network tools and technologies are used, it also helps maintain the smoothness, reliability, and security of the

I. Wireless intrusion threats Like wired LAN, wireless LAN is also under many security threats. Wireless LAN brings great convenience to users, and security issues are also worth noting. It also provides security problems that do not exist in wired

Overview The CDMA system is a self-interference system. A user is interference with other users. Each cell also interferes with other cells, especially adjacent areas with the same carrier frequency. At the same time, the residential area has the

WiMAX revolution WiMAX and voice communication are different from each other. It was initially designed as a wireless IP system. WiMAX not only reduces costs from the perspective of chipset, but also provides services from the perspective of

As an international standard proposed and adopted by China in the third generation mobile communication system, TD-SCDMA standard has been widely concerned around the world since its birth. After nearly 10 years of development, the TD-SCDMA system

Before creating a Wi-Fi wireless network, you must prepare a wireless network card and a Wireless AP. If the computer does not have a wireless network card, you can purchase an 802.11b wireless network card with interfaces such as PCMICA and USB of

Let's make a bold prediction. Where do you think the center of wireless applications will be in the future? Enterprise/campus wireless lan? Home wireless network? Or is it a ubiquitous Public Space Network? Perhaps none of them. From the current

HSDPA (high-speed downlink group access) is used to implement high-speed downstream data services of the WCDMA network, enabling the downstream data rate to reach 8 ~ 10 Mbps, known as the main solution of the 3G era. For HSDPA systems using

1. Optical Fiber TypeSilica B1.1 single-mode optical fiber.2. operating wavelengthCapacity Indicators meeting the 13l0nm and 1550nm transmission windows3. Cut-off wavelengthThe λ c value tested on 2 m coated optical fiber is 1100cm ~ The λ cc value

Question 1: Why do I need to perform a two-way test on the optical fiber? A: No two are exactly the same as the optical fiber. We must keep this in mind. The diameter of the skin from their core to the outside is different, and the ring and

In the eyes of many people, the Integrated Wiring System is very simple. In fact, when designing the distribution frame combination of the management subsystem, they often feel troublesome. Because a well-considered and reasonable structured cabling

A network testing team of Siemens Germany, supported by the European Union, recently announced that they have successfully tested the passive optical fiber network. This test not only made a new breakthrough in the speed of data transmission
