5-20 VMS User Guide
Policy Tab
From the InBand Manager Policy tab you can set the global policies under
which switching will occur in the Vipersat network. These policy settings are
set globally for all networks and are propagated down to all remotes in the
system. Independently each remote’s policy will inherent the global policies,
but the operator may choose the break the inherent settings and configure each
site independently.
The check boxes at the top of the tab allow you to enable or disable the follow-
ing functions:
• Automatic Switching
• Load Switching
• Scheduled Switching (Using VCS)
Bitrate Limits
In the Bit Rate Limits box you can set the Minimum, Maximum, and Excess
bit rate limits for the network. These values are used to determine the load
switching bit rate trigger points.
Minimum - This is the minimum bit rate value for all circuits on the site.
Maximum - This is the maximum bit rate value for all circuits on the site.
Excess - This value is added to application switched circuits to accommo-
date momentary excess data flow.
Application Policies
Application Policies are created here at the global system level, but can be either
modified or disabled at the site level (Subnet Manager) to accommodate
specific site requirements. In the Application Policies box you can Insert,
Modify, and Remove policies for individual circuit types, then either select or
de-select these policies once entered.
Right-clicking in the blank area of the Application Policies box displays a drop-
down menu for Inserting a policy. Right-clicking on an existing policy displays
a choice to Insert a new policy or Remove the existing policy. A policy can be
modified by double-clicking on the policy to enter the edit mode which allows
the Type, Minimum bitrate, and Maximum bitrate parameters to be changed.
Choosing Insert displays the Application Policy dialog shown in figure 5-25.
