What is a VPN?
- A VPN is a private network that is established
within a public network.
- Could either be created in a carrier's network or
over the Internet.
Why Use a VPN
Keep data confidential through encryption
Ensure the identities of the parties
communicating through authentication.
Provides safeguard for the communicating parties
through tunnelling.
Ensure data is accurate and in original state
through non-repudiation.
Types of VPN
• Internet VPN:
– Use certain protocols, such as: IPsec, L2TP and PPTP
to provide secure "tunnels" over the Internet.
• Frame Relay VPN:
– A carrier offers point to point and multipoint VPN
using frame relay.
– This type supports any network protocol.
– Can be costly, when adding locations in multipoint,
this calls for provisioning more virtual circuits from
one site to all others.
Types of VPN
• Virtual IP VPN:
– A carrier offers multiport networks.
– Only accepts packets sent from customer.
– Virtual Private Routed Networks connect the
customer's IP router to the provider's IP router.
– This connection requires some coordination.
• Ethernet VPN:
– A carrier has services that encapsulate Ethernet
frames.
– These frames connect the two sections of network.
