Executive Summary (This is a document excerpt)

In the next two years, more than half of North American and European enterprises will refresh their LAN infrastructure. To better understand how firms tackle LAN infrastructure upgrades and add-ons, Forrester inquired about the adoption of five LAN infrastructure technologies. What did we find? Currently, more than one-third of enterprises use virtual LANs (VLANs) and power over Ethernet (PoE), and, despite the recent vendor hype and mergers and acquisition activity in the market, application/WAN acceleration is only found in 11% of enterprise LAN infrastructures today. Port-based authentication will see the largest adoption increase in the coming year, as 13% of the enterprises planning to refresh their LAN switches and routers within the next year are already piloting the technology.
