A detailed explanation of VPN Ethernet access technology in LAN

    LAN on VPN Ethernet access technology in the detailed, broadband popularization, often face the problem of VPN Ethernet access technology. So, today I am going to introduce VPN Ethernet access technology settings skills, I hope this article can teach you more things, for everyone's life bring convenience.

Ethernet has become the most widely used network technology since the 1980s, and according to IDC, the number of ports in Ethernet is about 85% of all network ports. 1998 Ethernet card sales are 48 million ports, and the token network, FDDI network and ATM network cards, such as the total sales of 5 million ports, but the entire sales of 10%. This advantage of Ethernet still has the momentum to keep going.

Traditional Ethernet technology is not part of the VPN Ethernet access technology network but belongs to the domain of the user Resident Network (CPN). However, its application area is extending to other public networks, including access network. Historically, Ethernet technology has been the most popular method for enterprises and enterprise users, and the main reason of using Ethernet as Access means is: (1) Ethernet has a huge network foundation and long-term experience knowledge; (2) Currently all popular operating systems and applications are compatible with Ethernet.

Better performance, scalability, ease of installation, and high reliability; (4) Ethernet access mode and IP network is very adaptable, at the same time Ethernet technology has been a major breakthrough, capacity is divided into 10/100/1000mb/s three levels, can be upgraded on demand, 10GB/S Ethernet system is also coming out. 3lian.com

A broadband access network based on Ethernet technology consists of a local side device and a user side device. Local equipment is generally located in the community, the user side equipment is generally located in residential buildings, or the local equipment located in the commercial building, while the user side equipment located in the floor. The local side equipment provides the interface with the IP backbone network, the user side device provides the 10/100base-t interface with the user terminal computer. The local side equipment has the function of gathering user side equipment management information. The

Broadband VPN Ethernet access technology has a powerful network management function. As with other VPN Ethernet access Technology network technology, can be configured management, performance management, fault management and security management, but also to the billing system to provide a wealth of billing information, so that the billing system can be based on the amount of information, according to the length of the connection or monthly system billing methods.

High-VPN Ethernet access technology based on five types of lines is undoubtedly a better choice. It is especially suitable for the intensive living environment, which is very suitable for Chinese national conditions. Because the living situation of Chinese residents is not like the Western developed countries, the individual users live scattered, the Chinese households mostly live, this is particularly suitable for the development of fiber to the community, and then Fast Ethernet connection to the user VPN Ethernet access technology.

in the LAN IP protocol is running on the Ethernet, that is, IP packets are encapsulated directly in the Ethernet frame, Ethernet protocol is currently the best one with IP protocol. VPN Ethernet access technology has become a new trend of broadband access, it will quickly enter the family. At present, most of the commercial buildings and new residential buildings have been integrated wiring, cloth put 5 kinds of UTP, Ethernet jack cloth to the table.

VPN Ethernet access technology can provide each user with a 10mb/s or 100MB/S VPN Ethernet access rate, which has several times or dozens of times times more bandwidth than other methods. Can fully meet the user's need for bandwidth access. Although ADSL is faster than 56K, but compared with Ethernet, there is still a big gap, it is only one of the transition technology in the process of broadband.

ADSL and cablemodem costs are high, the cost and cost per household will be more than 1000 yuan. and the cost of Ethernet per household is about hundreds of yuan. So VPN Ethernet access technology, in the performance price ratio is not only suitable for China's national conditions, but also in line with the future development trend of the network. In commercial buildings and new high-grade residential buildings, VPN Ethernet access technology will be the most promising VPN Ethernet access technology means
