This IDC study contains IDC's actual 2004 and 2005 LAN switch results and IDC's 2006-2010 forecast estimates for Western Europe port shipments, revenue, average selling price (ASP), and installed base.

Forecasts are provided by technology for Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet (10GbE), by Open Systems Interconnection (OSI) layer for Layers 2, 3, and 4-7 and by form factor for modular, nonmodular, and unmanaged LAN switch port shipments, ASP, installed base, and revenue.

"IDC expects the Western European LAN switch to benefit from the fact that organizations are transitioning from 10/100 Mbps Fast Ethernet towards 100/1,000Mbps Gigabit Ethernet," said Peter Hulleman, research manager in IDC's European Telecommunications and Networking team.
