A TTP has two administrative states that let you enable/disable TTP throttling. The Throttling Admin State is used to disable all throttling (both static and dynamic). When enabled, it automatically enables Static ETR throttling and might or might not perform Dynamic ETR throttling/DOIC as that is determined by the TTP's Dynamic Throttling Admin State.
Note:
The TTP's Dynamic Throttling Admin State is not used to determine the TTP's Operational Status value.
The page allows you to view information about and change the administrative state of TTP.
You can perform these tasks on an Active System OAM (SOAM).
You can perform the following actions for Traffic Throttle Points:
- Filter the list of Traffic Throttle Points (individually or multiples).
- Sort the list by column contents, in ascending or descending order, by clicking the column heading. The default order is by TTP in ascending ASCII order.
- Select a Traffic Throttle Point Name in the list.
You cannot change the TTP maintenance screen to change the Dynamic Throttling state to Disabled to Enabled when Throttling state is Disabled.
You can change the TTP maintenance screen to change the Dynamic Throttling state from Enabled to Disabled when Throttling state is Enabled.
TTP Throttling Admin State
When you change a TTP's Throttling Admin State is to Enabled:
- The routing instance starts sharing OTR data associated with the TTP with other DA-MP's within the DSR Node.
- If the TTP's Dynamic Throttling Admin State is set to Enabled and the TTP's Peer Node Operational Status is Available, the routing application starts sending a DCA to the Peer Node in all Request messages associated with this TTP and processes DOIC AVPs received from the Peer Node.
- TTP's Operational Status/Reason are updated.
When you change a TTP's Throttling Admin State to Disabled:
- Stop any Maximum ETR Throttling associated with this TTP.
- Ignore the TTP's Maximum Loss Percent Threshold during routing decisions.
- Stop sharing OTR data associated with the TTP with other DA-MP's within the DSR Node.
- Abandon all dynamic throttling (functional equivalent to TTP's Dynamic Throttling State being set to Disabled.
- The Current Loss Percent for all TTGs associated with this TTP are recalulated.
- TTP's Operational Status/Reason are updated.
TTP Dynamic Throttling Admin State
The routing application ignores any changes to the TTP's Dynamic Throttling Admin State when the TTP's Throttling Admin State is set to Disabled. When a TTP's Throttling Admin State is set to Enabled, the routing application process changes to the TTP's Dynamic Throttling Admin State as follows:
- TTP's Dynamic Throttling Admin State changed from Disabled to Enabled.
- TTP's Dynamic Throttling Admin State changed from Enabled to Disabled.
