This IDC study is one of several documents in which IDC presents the results of its annual U.S. WAN Manager Survey. This document presents the company size segmentation view of U.S. businesses' adoption of managed network services.

Melanie Posey, research director for Telecom Markets, says, "IDC's research continues to show that larger companies are significantly more likely to be current users of managed network services than their smaller counterparts. There is considerable scope for further penetration in the large enterprise segment, but the small and medium-sized business segment remains a relatively untapped market."
