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
