Global Local Policy Termination

The Oracle® Enterprise Session Border Controller can be configured to limit local policy lookups based several aspects of the route lookup process:

  • Limiting the number of stages per message lookup—The Oracle® Enterprise Session Border Controller can limit to the number of additional local policy lookup stages it will perform received message to a maximum of 5. This is configured with the additional lp lookups parameter. Leaving this parameter at its default value of 0 essentially disables multistaged local policy lookups.
  • Limiting the number of routes per Local Policy lookup—The Oracle® Enterprise Session Border Controller can limit the number of route results to use as returned for each Local-Policy lookup. This is configured with the max lp lookups routes per lookup parameter. Leaving this parameter at its default value of 0 places no limit on the number of returned routes the Oracle® Enterprise Session Border Controller can try.
  • Limiting the total number of routes for all local policy lookups per message request—The Oracle® Enterprise Session Border Controller can limit the number of route returned in total across all lookups for a given request, including additional stages. This is configured with the total lp routes parameter. Leaving this parameter at its default value of 0 places no limit on the number of returned routes the Oracle® Enterprise Session Border Controllercan try. This parameter overrides any configured options.

Additionally, the Oracle® Enterprise Session Border Controller monitors for local policy lookup loops which could cause a significant deterioration in performance. If a loop is found, the Oracle® Enterprise Session Border Controller stops trying the looping route list and proceeds to try any remaining routes..
