11.1.5 VPN settings
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 suspend-and-resumes their devices
to preserve battery life. A conventional VPN cannot 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, please refer to “
