Menu Options/Fields Entry Description
DES Key # The DES Key field allows the user to specify which DES
Key should be selected for a route.
This parameter will assume one of (4) values:
1. Clear
2. Key1
3. Key2
4. Random
The value of CLEAR will force the CiM to not encrypt any
traffic destined for the satellite.
The value of Key1 will use the key specified in the Des
Encrypt Configuration Page/Transmit Key 1 menu option
to encrypt traffic destined for the satellite.
The value of Key2 will use the key specified in the Des
Encrypt Configuration Page/Transmit Key 2 menu option
to encrypt all traffic processed by the CiM.
The value of Random will cause the CiM to randomly use
either Key1 or Key2 to encrypt all traffic destined for the
satellite.
Base B The QoS/DES menu allows the user to view up to 8
different routes per screen. To allow editing on any of the
1024 entries that can be defined, the user can select a
base address to control which 8 routes are displayed. For
example, if the user wants to edit Routes 32-40, then a
Base value of 32 should be defined.
Save Parameters S This option allows a user to save the current configuration
of the CiM to permanent storage. This configuration will be
restored on each successive power cycle of the CiM.
Exit X This option allows a user to exit the current menu and
return to its parent menu.
Note: If a user sets both the guaranteed and maximum bandwidths assigned to a route to 0,
then packets will be randomly dropped for that route only when the resources of the
carrier are being over-utilized.
9.1.2.1.1 Example Implementations using QoS and QoS
Prioritization
The combination of MIN and MAX Bandwidth QoS combined with QoS Prioity allows
for multiple levels of QoS implementation. We recommend that QoS is configured using
one of the following formats:
PRIORITY with MAX BW - All routes are configured with the default value of
0 for MIN and can have a MAX BW defined to limit the amount of BW used by a
route. Routes are designated as Priority 1 or 2.
Note: This is would be used when wanting to prevent the Priority 1 traffic from using all of the BW
Priority 2 traffic could also be limited to a maximum BIN usage.
