In early 2008, Vancouver, Washington-based New Edge Networks, the business
communications unit of EarthLink Inc., inaugurated its revolutionary MPLS over DSL
service, allowing five classes of service over a DSL connection. With this offering,
the first of its kind ever, New Edge is radically changing the network landscape by
allowing the bi-directional use of MPLS classes of service over DSL.
New Edge has drastically lowered the price point at which a small enterprise can
enter the MPLS world. As applications like SAP filter down to smaller businesses and
technologies like VoIP become more attractive, it is necessary for enterprises that
wish to use these tools effectively to strengthen their network infrastructure to
support them. Before the advent of MPLS over DSL, this meant that it was
necessary to have, at a minimum, a T1 line at every location. As T1 lines cost
roughly four to five times the cost of a DSL connection, this is a major impediment to
the adoption of these new tools.
