11.1.5 VPN
A mobile virtual private network (mobile VPN or mVPN) provides
mobile devices with access to network resources and software
apps on their home network, when they connect via other wireless
or wired networks. Mobile VPNs are used in environments where
workers need to keep app 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 apps to
disconnect, time out, fail, or even the computing device itself to crash.
For more information on VPN, please refer to "6.5 Connect to
virtual private networks".
