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-toBusiness (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 communications environment. They meet several needs for expanded communications and typically can be implemented in a manner that provides a quick return on investment.
