Fields:
•
Start
and
End
time: defines the time period (specified in 24 hour notation).
•
Score
: the value that will be added for determining the network selection.
A.1.4 Velocity Policy
Switches networks based on the velocity of the vehicle. This allows for proactive
network switching instead of relying only on network outage switching. For
example, you may prefer to give WiFi a preference while stationary (e.g. in a
depot) and cellular a preference while moving.
Fields:
•
Threshold
: the velocity at which the WAN link is penalized.
•
Penalty
: the amount to reduce the priority score when the velocity exceeds
the threshold. It is applied by subtracting the value from the current score.
The penalty is removed when the velocity drops below the threshold for the
amount of time specified in Threshold.
•
Recovery Period
: the period of time the vehicle’s velocity must remain below
the threshold for the penalty to be removed.
A.1.5 Signal Strength Policy
Switches networks based on the signal strength of the WAN connection.
Signal Strength Threshold (dBm)
: the threshold of signal strength below which
a penalty should be applied.
Penalty
: the amount to reduce the priority score when the signal strength falls
below the threshold. It is applied by subtracting the value from the current score.
The penalty is removed when the strength increases above the threshold for the
amount of time specified in Signal Strength Threshold. Note that the penalty is
removed linearly during the recovery period and recovers completely when
reaching Recovery Period (see below) after the signal strength increases above
the threshold.
Recovery Period (sec)
: the period of time the signal strength must remain above
the threshold for the penalty to be removed.
A.2 Networking Rules
A.2.1 Access Blocking
Adding an Access Blocking rule will block all incoming or outgoing traffic (from the
oMG’s perspective) based on the following criteria:
•
Source IP address
•
Source Port range defined by the first and last port, inclusively, of the range
•
Protocol: TCP, UDP, Both or Internet Control Message Protocol (ICMP)
•
Destination IP Address
