Types of protocols used in VPN Tunneling
VPN is the initial used for Virtual Private Network. VPN allows you to send data as well as receive data within the private network. The transferring of data is done through the point to point connection.VPN creates a safe and secured within the worldwide web. Your data is safe while using a Wi-Fi connection in front of hackers and prying eyes. Even if the hacker is able to know the IP address, they will be unable to retrieve your personal details as it is encrypted through various protocols.
The VPN has servers in 24 countries of the world therefore it becomes difficult to locate your IP address as it is masked through the different local server. You may want to visit a site but concerned about the security of your IP address. With the help of this VPN service you will be able to access the site without disclosing your true IP address.
VPN or Virtual Private Network creates a virtual office to make full use of the potential of your employee. You can work at home or in the office through VPN as if you are working in the office space.
VPN enables you to visit restricted or blocked sites to your IP address. You can see geolocation restricted sites such as BBBiPlayer, 40D, LoveFilm etc from UK or Netflix from USA from any part of the world as it shows that the IP address is originating from within the country.
VPN tunnel works as a subway network. It helps to create a network that is safe and secure in between the public networks. VPN tunnel uses software that works as gatekeeper. It closes and opens at client’s order. A datagram based protocol is used in the tunnel to ensure the parameter of the both end is the same. While transporting the information through tunnel data is encrypted and decrypted when the receiver receives the data.
Types of VPN Tunneling
There are two types of VPN tunneling used. They are voluntary and compulsory.
Voluntary VPN tunneling is set up by the client. The client creates a tunnel with the service provider. In voluntary tunneling connection is set up two steps.
In compulsory tunneling the connection is made through the carrier network. Therefore it is a single step set up in comparison to the two step setup of the voluntary tunneling.
Protocols used in Tunneling
Various numbers of protocols are used in VPN tunneling. There are mainly three protocols that are used in VPN tunnel.
Layer Two Tunneling Protocol (L2TP)
This protocol is created and developed by CISCO and Microsoft. The best qualities of L2P and PPTP are combined in this protocol.
Internet Protocol security (IPSec)
IPSec is a protocol which is used in VPN tunneling. They are created with various features of different protocols. Therefore it is profitable option to use Internet Protocol Security (IPSec).
Point to Point Tunneling Protocol (PPTP)
PPTP is used for dial up network connection. It helps to access from remote areas while using the VPN.
There are also few other tunneling protocols that are used in VPN.
