5.4 Setting up a Link Policy
After configuring WAN link(s), it's recommended that one or more policies be
defined for each link.
Policies are one of the more powerful features of the oMG because they provide a
variety of ways to maintain network connectivity across a range of external
conditions.
The oMG includes a rich set of configurable policies, which define how and when
the various WAN devices installed in the unit should provide connectivity. These
policies can help maintain connections as signal strengths fluctuate, and can help
to maintain the most optimal and cost efficient connectivity.
This section describes how the various policies work and how to tune them for
optimal connectivity and performance. Since policies can be set up to work in
concert with other policies across links, this section includes a discussion and
examples on how to set up multi-policy configurations.
Policies determine which link should be used based on some sort of criteria such
as stability. Selection is based on a scoring system where
penalties
for issues
(e.g. a link being down) reduce a link's score. Each link is evaluated based on its
score and the link with the highest score is set to the active link. Policies can be
combined to form an arithmetic score that affects active link determination.
The general goals for implementing policies are as follows:
•
Reduce or eliminate loss of connectivity and associated downtime
•
Reduce or eliminate issues associated with the loss and re establishment of a
connection such as having to rebuild a VPN connection
•
Maintain a stable connection
•
Maintain the fastest throughput available
•
Reduce cellular usage costs
•
Use "low cost" links including WIFI
To achieve these goals and make the most of these policies, oMGs are usually
equipped with multiple WAN devices which include both WiFi and multiple cellular
devices. This allows for the managed switching between these devices as defined
by the policies.
Policies work on a system of scores which can be decremented (penalized) when
some condition is exceeded (e.g. a connection is lost), and gradually incremented
again once the condition has been met (e.g. a connection is eventually
re-established).
These parameters allow for the dynamic selection of links based on a variety of
factors and multiple policies can be combined to select a link amid a wide range
of external and environmental factors.
