Figure 3-82 Application Policy Settings
Application Policy Type numbers have the following convention:
0 — ECM Load Switching
1 — Scheduled Switching and VFS
2 — Voice
3 — Video
4–63 — Reserved for the System
64–253 — User Defined
254 — Uninterruptable Switch / Immobile Carrier (such as for video; used
to ensure that additional applications will not generate a switch, thus
preventing video glitches)
Priority levels can be assigned to application policies as well as to sites.
Resource allocation preference is based on the highest priority among
contending sites and/or policies. Note that a lower number corresponds to a
higher priority level. Priority 1 is the highest level. Priority 0 (default)
equates to No priority.
The policy priority level determines the likelihood that:
• The requested bandwidth will be allocated, should there be contention
with other policies.
• A carrier that is assigned to this policy will get resized based on
bandwidth availability. Policies with higher priority levels are more
likely to retain their requested bandwidth during periods of bandwidth
contention than those policies that have lower priority levels.
Both Tx and Rx Bit rate parameters are presented, for accommodation of
P2P configurations.
