Note that the scores match in the overlapping region, so a switch between cellular
links will not occur when entering the overlapping zone in order to prevent an
unnecessary switch as illustrated in
Figure 5-11: Geographic Region Example with overlapping Regions
Tip:
Configuring the bounding boxes for each region requires knowledge about the
latitude and longitude coordinates for the upper and lower points which make up each
region, since the oMG's LCI does not provide a mapping interface to visually define zones.
Therefore, configuring this policy will require you to determine the coordinates to be
entered in the policy.

5.4.4 Time Period Policy Overview
The
Time Period Policy
promotes one link over others when operating within a
defined time period. Up to three time periods can be defined per link. This can be
used to make use of reduced data costs or to compensate for bandwidth
saturation periods.
For example, when a link's throughput is known to drop during a particular time of
day (e.g. due to network congestion), a time period could be defined on a backup
link for this known period with a fairly high score applied, so that the backup link is
temporarily selected and used to maintain acceptable throughput.
Another use case includes switching to the link of a Mobile Network Operator who
provides cheaper cellular coverage during evenings.
