This IDC study discusses how the ATM switch market continues to struggle as leading network service providers (NSPs) start their migration to an all-IP network. Despite these challenges, the ATM switch remains an essential component of the NSPs' ability to offer frame relay and ATM services.

"Increased demand for wireless backhaul and consistent government/enterprise demand continue to stabilize the size of the market. 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." - Lee Doyle, group VP, Network Infrastructure
