Networking - What is Tunneling?

What is Tunneling?

- Tunneling is a mechanism provided to transfer data securely between two networks.

- The data is split into smaller packets and passed through the tunnel.

- The data passing through the tunnel has 3 layers of encryption. The data is encapsulated.

- Tunneling can be approached by Point to Point tunneling protocol.

- It allows the private network communication to be sent across a public network.

- The encapsulation process allows the data packets to appear as they are of a public nature in the public network.

- It is also known as port forwarding.
