operators is that Ethernet needs to be rewired from scratch. Due to the architecture of EthernetOverVDSL over telephone lines, the telephone lines in the home are almost ready-made, which can save a lot of money and be cost-effective for development. At present, the open rate of Ethernet broadband access network is still very low in the domestic market, which increases the investment and operation risks of service providers. The cost-effectiveness br

In China, the mainstream broadband access mode has the following several: Adsl,vdsl,fttb+lan dynamic Ip+web certification, Fttb+lan static Ip+web certification, cable broadband Internet access. Many access schemes have adopted a router, but compared to different access methods, the router's setting method is not the same, today to use more compatible with the Tp-link broadband road as an example, in detail on the different broadband mode access to the

broadband access network. A few years ago, China's Telecommunications exchange network has been transformed, so that the current Exchange network to show a large capacity of the characteristics of less bureau. In this network environment, the Broadband access network construction also must adapt to this characteristic.ADSL Technology and VDSL technology are two kinds of mainstream DSL technology at present, but these two kinds of technology have each

When it comes to access networks, we must first involve a bandwidth problem. With the continuous development and improvement of Internet technology, the bandwidth of access networks is divided into narrowband and broadband. Industry experts generally think that broadband access is the future direction of development. The network structure of the broadband carrier is shown in 1. The entire city network consists of the core layer, convergence layer, edge convergence layer, and access layer. The a

Understanding some knowledge about TP-LINK router settings, for TP-LINK router users is very important. In China, the mainstream broadband access modes include ADSL, VDSL, FTTB + LAN Dynamic IP + WEB Authentication, FTTB + LAN static IP + WEB authentication, and wired broadband access. Many access solutions are using the router, but compared with different access methods, the TP-LINK router setting method is not the same, today is to use more compatib

This article discusses several mainstream authentication methods applied in the industry from several aspects, pppoe authentication technology, web authentication technology, and 802.1x authentication technology.Key words: pppoe, web, 802.1x, authenticatio

With the rapid development of the Internet, communication technology is experiencing a huge revolution, because the number of users accessing the network rapidly increases. As a network connected to the end users in the communication network, the access network has become a hot topic in network technology. Currently, the main access technologies include hybrid fiber/coaxial (HFCs) access technology, optical fiber access technology, copper wire access technology and wireless access technology. Co

In China, the mainstream broadband access modes include ADSL, VDSL, FTTB + LAN Dynamic IP + WEB Authentication, FTTB + LAN static IP + WEB authentication, and wired broadband access.

, it is particularly suitable for search-type network services. The typical upstream speed of ADSL is 1.544-8.192 kbps, the downstream speed is 6 km-Mbps, and the transmission distance is 3-. ADSL is a standard transmission service. The ADSL Broadband Access Network Technology can share the same user line with the phone service. In actual application, there is a problem with the line selection rate of ADSL. Generally, the line selection rate is about 10%. In addition, the rate of ADSL decreases
