Virtela's MPLS-SF is able to bring together the world's top MPLS networks in a "supernetwork" arrangement, an industry breakthrough that solves the lack of interoperability and limited reach of single provider MPLS networks. Until now, enterprises looking to truly exploit the benefits of MPLS were hamstringed by carriers' collective resistance to interconnect their MPLS networks, a lack of desire driven by business interests above any technological or standards hurdles.

Virtela's MPLS architecture has its heritage in Virtela's original IPSF network, which routes VPN traffic across the world's top IP networks for thousands of enterprise locations across six continents. Virtela's regional policy centers can now also route MPLS traffic throughout the world across 200+ best-of-breed carrier networks, using proprietary routing algorithms to direct traffic over the best performing path at any given time. The MPSF-SF honors each class-of-service attribute for the originating carrier, and maps multiple classes-of-service across carriers to achieve the highest-quality, end-to-end MPLS service available today.

"Virtela has put the industry on notice once again with its latest offering, the MPLS Service Fabric," said Michael Suby, senior research analyst with Stratecast Partners (a Division of Frost & Sullivan). "Virtela's IPSF proved that the performance associated with a closed, single-carrier network can be exceeded through a managed collection of IP networks. Leveraging this same network design, Virtela raises the bar with MPLS-SF by addressing the inherent limitations of a single-carrier MPLS network, creating an MPLS alternative that is worthy of serious enterprise consideration."
