This IDC study discusses how the ATM switch market continues to struggle as
leading network service providers find themselves under pressure to reduce
capital expenditures. The overall market declined more than 6% during 2003 and
is forecast to decline an additional 3% during 2004. Despite these challenges,
the ATM switch remains an essential component of the ability of NSPs to offer
frame relay and ATM services ? a $25 billion market and one forecast to grow
moderately over the next few years. Expected demand for more than 90 million
new DSL subscribers will also help to stimulate sales, as the ATM switch
remains a key part of DSL aggregation. Price erosion and technology competition
from IP/MPLS routers remain as market inhibitors. The ATM switch will continue
as a key part of most large NSP networks, but it is unlikely to be a growth
market for network equipment providers.
"A key problem for ATM switch suppliers is their quest to remain relevant as
all major carriers have publicly committed to an all-IP network" ? Lee Doyle,
group VP, Network Infrastructure
