Traditionally VPNs (Virtual Private Networks)
operate over the Internet, creating a virtual
"tunnel" between two or more connected
sites.
For example, when you want to connect to MS Outlook
at the office from home, you create a VPN connection
to the office network. This connection means your
PC/laptop acts as if it is part of the office
network.
While this is acceptable for light usage, it can
become a problem when you want to send/receive
a lot of data.
VPNs can be rather cumbersome, because for each
packet that you send/receive, a little bit of
overhead is added because of the encryption used
between the two sites.
The other downside to this is that there are download
costs at both ends - which can amount to a fair
bit over time.
However, with the recent advances in DSL technology
we can now remove the "V" from VPN,
and create a fully private network that never
touches the Internet.
Companies such as NEXTEP and RequestDSL are able
to provide point-to-point connections (PPCs),
which means that instead of "pretending"
to be part of the remote network, you actually
ARE part of the network.
An example of this would be the recent connection
we installed for Young & Rubicam.
They now have a PPC going between their office,
and their server at the Connect data centre. Because
the traffic is "off-net", there are
no security issues, and no download costs. They
can now transfer gigabytes of data every month
without it costing anything.
