ABSTRACT
Increasingly, virtual private networks (VPNs) are being
adopted for many uses, which range from remote access
and small office/home office (SOHO) support to Business-
to-Business (B2B) communications. Almost as soon as the
technology became available, organizations of nearly all
business verticals began implementing VPNs in some form
or another. Regardless of the business type or market,
VPNs seem to permeate all walks of life in the commu-
nications environment. They meet several needs for
expanded communications and typically can be implemen-
ted in a manner that provides a quick return on investment.
