The industry has long debated which technology is superior for global enterprise Wide Area Networks (WANs): multiprotocol label switching (MPLS) or Internet-based virtual private networks (VPNs). While some argue that Internet-based VPNs are preferable because of their flexibility, scalability and cost benefits, others swear by MPLS for its reliability and performance (albeit expensive) characteristics. Frost & Sullivan points out that the choice of MPLS versus Internet comes down to whether the CIO is comfortable with entrusting his/her company’s applications to the Internet - or prefers to just keep them on a private network that does not touch the Internet. However, Frost & Sullivan research confirms that the growing penetration of cloud-based applications and mobility is forcing enterprises to reevaluate their networking strategies.
