Executive Summary (This is a document excerpt)

In the US, enterprises are steadily moving off legacy WAN services like frame relay (FR) and asynchronous transfer mode (ATM) and onto IP-based services like multiprotocol label switching (MPLS). This is reflected in the WAN-related inquiries Forrester received from IT end users in the United States. Between January 1, 2008 and October 15, 2008, 68% of these specified interest in MPLS services. Clients inquired about the advantages of using MPLS versus other WAN services; market trends related to adoption; implementation considerations; and best practices in negotiating, implementing, and managing MPLS networks. But the single most popular category of inquiry was comparing the benefits and drawbacks of using prospective MPLS providers.
