Abstract
A recent survey by In-Stat shows that legacy services (i.e., frame relay, leased line, and ATM) remain a dominant component of the communications landscape, but this service segment is in the process of a significant transition.
Legacy services continue to provide US organizations with reliable communications, but organizations are under pressure to provide connectivity to the network on an "anywhere/anytime" basis. In this changing environment networks are moving more toward "multi-point" type implementations, that support convergence.
Legacy services struggle to keep up in this changing environment. In contrast, Internet access and next-generation network (NGN) services, which for purposes of this report are defined as IP/MPLS and Ethernet VPN services, are well suited. As such, the data services being used are in transition.
Taking an overall US market perspective, the report outlines the transition taking place from legacy services to Internet access and NGN services.
Drawing extensively on In-Stat' s 2008 NGN Services survey, the report provides valuable insight into the migration taking place from the "buy-side" perspective, including:
- Business drivers and applications that are currently influencing service purchasing decisions
- Deterrents that inhibit migration
- Estimates of legacy service site migration activity
- Adoption of converged implementations and QoS
- WAN services to be added/expanded over the next year
