Types of VPN Tunneling protocols used in
VPN is the first used for Virtual Private Network. VPN allows you to send data and receive data within the private network. The data transfer is done via point to point connection.VPN creates a safe and secure on the web worldwide. Your data is safe while using Wi-Fi opposite hackers and prying eyes. Even if the hacker is able to know the IP address they will be unable to recover your data as it is encrypted through various protocols.

VPN Tunnel
tunnel corporate VPN as a subway system. It helps to create a network that is safe and secure from public networks. VPN tunnel uses software that works as a doorman. It opens and closes at the customer order. A protocol datagram-based is used in the tunnel in order to ensure the setting of the end of the two are the same. While the transport of information through tunnel data is encrypted and decrypted when the receiver receives the data.
Types of VPN Tunneling
There are two types of VPN tunnels used. They are voluntary and mandatory.
voluntary VPN tunnel is established by the client. The client creates a tunnel with the service provider. In voluntary tunneling framework is put in place two stages.
In compulsory tunneling connection is made via the operator's network. It is therefore a single stage set up with respect to the configuration in two stages of voluntary tunnel.
The protocols used in tunneling
Various protocol numbers are used in VPN tunneling. There are three main protocols used in the VPN tunnel.
Layer Two Tunneling Protocol (L2TP)
This protocol is created and developed by Cisco and Microsoft. The best features of PPTP and L2P are combined in this protocol.
the Internet Protocol security (IPSec)
IPSec is a protocol that is used in VPN tunneling. They are created with various characteristics of different protocols. Therefore, it is cost-effective option to use Internet Protocol Security (IPSec).
Point to Point Tunneling Protocol (PPTP)
PPTP is used to dial the network connection. It helps to access remote areas while using the VPN.
There are also some other tunneling protocols that are used in VPN.
