In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward
1. About VPN
(1) Virtual Private Network (VPN) is an extension of a private network. It contains Internet-like shared or public network connections. Through VPN, data can be sent between two computers through a shared or public network through a simulated point-to-point dedicated link.
(2) If it is more common, VPN is
To sum up, a VPN is a private connection that is established between two machines or two networks by sharing a public network. In fact, VPN technology enables organizations to safely extend network services over the Internet to remote users, branch offices, and cooperative companies. In other words, the VPN turned the internet into a dedicated WAN for impersonati
ADSL is called asymmetric Digital subscriber line. ADSL is called asymmetric because its two duplex channels are used to transmit data to the user, only a small portion of the bandwidth used to send back to the user's information. ADSL on a pair of copper wire support upload rate 640kbps~1mbps, 1mbps~8mbps rate, effective transmission distance within the 3km~5km range.
The application of ADSL
ADSL LAN users with 4 fixed static IP address, the application of ADSL LAN form network units can be s
Now there are still a lot of VPN Router applications, and the market demand is also very high, so I studied the VPN Router's questions about VPN multi-channel bundling, here I will share with you, I hope it will be useful to you.

RainerEnders is the CTO of NCPengineering for VPN security in the Americas. In this article, we will learn how VPN security vulnerabilities are ge
ADSL is called an asymmetric digital user line. ADSL is called asymmetric because its two duplex channels are used to transmit data to users, and only a small portion of bandwidth is used to send user information back. ADSL supports the upload speed of kbps on a copper-to-copper line ~ 1 Mbps, 1 Mbps ~ 8 Mbps, valid transmission distance between 3km ~ Within the range of 5km.Application of ADSLAdsl lan users have four fixed static IP addresses. enterprises applying for access through the adsl la
