Components of the VPN
When using VPN we incorporate many pieces of a jigsaw puzzle each piece services its own function to private the interoperation and the security necessary to create a true service. The pieces include
a.VPN server: This is a computer that enables and accepts VPN connection from VPN client. The sever can provide a remote access connection or a router to router connection. The main essences is user to log on establish a VPN connection and be flexible enough to satisfy the number of simultaneous connections that we fell are necessary.
b.VPN client : The VPN client is a computer that initials the VPN connection. Usually a piece of software which is used to create the VPN and include necessary security procedures.
c.Tunnel: This is the virtual piece of the network that carries the data. Not all tunnels carry secure data but they all try to carry data on a private link. The data is encapsulated inside a new envelope so that the information is invisible inside the tunnel.
d.Connection : This is the place where the data gets scrambled and jumbled. Many choices for the encryption technique are available and selected on user preference.
e.Protocols: We saw that OSI layer 2 is a framing protocols fro the link. The same holds true in this case, we need a data link layer protocols to carry the information. When we dial up into the internet for example we transmit our IP datagram we sue layer2 protocols called the point to point protocols to frame the IP datagram's and carry them across the dial connection. In a VPN we see protocols that include the point to point tunnelling protocols and we now have layer 2 tunnel protocols. In a windows environment the use of PPP is currently more prevalent but the movement is toward L2TP.
f.Networks : The networks connections either a dial up connections the internet or another IP based network.
File servers are useful for sharing files through a network. With a file server, the client passes requests for file records over network to file server
