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

VPN (VirtualPrivateNetwork) is a virtual network established on the basis of the existing network, mainly used to help two networks communicate through the VPN tunnel. the advantage of VPN is that after the computer A1 in Network A is connected to the computer in Network B through A tunnel, A1 will be able to use the network environment of network B.
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
After Ubuntu is installed, the goal is to abolish windows. Of course, everyone knows that this is impossible. At least Visual Studio cannot get rid of it. But it is my goal not to use windows to the maximum extent.
In order to achieve the above goal, a large principle has been developed: If you can use Ubuntu, you don't need windows. If you can't, you can use windows in the office. In this way, a problem occurs. How can I use the office computer at home? The Organization provides a Cisco
