The European market for IP-based VPNs is growing rapidly but the current double-digit growth phase will flatten out to five per cent a year by 2007, according to IDC.
estimates that managed IP VPN services in Western Europe grew by
107 per cent during 2003 and that, of the five countries with the
largest growth, Italy grew the most (by 131 per cent).
due to several factors, including saturation in major companies and a
shift away from conventional IP VPNs to voice over IP and hosted
accounts for more than half of current connections and that, as MPLS
advances, so IPSec will reduce in popularity.
