10.1.7 More\VPN
A mobile virtual private network (mobile VPN or mVPN) provides mobile
devices with access to network resources and software applications on their
home network, when they connect via other wireless or wired networks. Mobile
VPNs are used in environments where workers need to keep application
sessions open at all times, throughout the working day, as the user connects
via various wireless networks, encounters gaps in coverage, or suspends-
and-resumes their devices to preserve battery life. A conventional VPN
can't survive such events because the network tunnel is disrupted, causing
applications to disconnect, time out, fail, or even the computing device itself
to crash.
For more information on VPN, go to "6.5 Connecting to virtual private
networks".
