Dimensions of VPN
solutions
----------
Hi,
I'm looking at
VPNs from an research
point of view and I'm
particularly interested
in classification of VPN
solutions.
What I
would like to achieve is
a definition of
dimensions of
VPNs(technical,
functional,
organzational,...) and a
classification based on
that.
This is related
to my master thesis and I
would be more than happy
if someone could give me
an piece of advice on
that.
Greetings
from
Munich,
Martin

Classification
----------
Here is some stuff about
VPN
classification.
VP
Ns can be classified
based on:
- The
business problem a VPN is
addressing. The major
classes of business
prob-lems are
intra-company
communication
(intranets),
inter-company
communica-tion
(extranets) and access
for mobile users (Virtual
Private Dialup Networks –
VPDNs).
- The OSI
layer at which the
service provider
exchanges the topology
information with the
customer. Major
categories are the
overlay model, where the
service provider provides
the customer with only a
set of point-to-point (or
multipoint) Layer 2 links
(usually ATM VCs) between
the customer sites, and
the peer model, where the
service provider and the
customer exchange Layer 3
routing information.
-
The topology of the
network: from simple
hub-and-spoke topology to
fully meshed networks and
multilevel hierarchical
topologies in larger
networks.
- The Layer
2 or Layer 3 technology
used to implement the VPN
service: X.25, Frame
Relay, ATM, IP, and
IPSec.
- The
infrastructure used as an
underlying transport,
which can be shared (ISP
backbone), or public
infrastructure
(Internet).
Read
RFC 2764 (A Framework for
IP Based Virtual Private
Networks).
