Goals:

  1. Enhance PAP to send only delta policies to DMaaP instead of the entire list of policies.
  2. Enhance PDP_UPDATE message to contain a list of delta policies and a boolean value to deploy/undeploy policies.

Currently PAP sends a full list of policies to the PDPs through DMaaP. The aim is to send only the necessary policies to DMaaP.

The PDPs can then determine to deploy/undeploy these policies based on the flag.


Current thoughts/suggestions:

  1. Enhance PDP_UPDATE message to contain two new lists (deploy and undeploy), while maintaining it's current full list of policies. When the PDPs support delta policies we can then remove the original full list.
  2. Enhance PDP_UPDATE message to contain one new list of policies to be updated, and a boolean value to determine whether to deploy/undeploy the policies while maintaining the full list of policies also. PDPs that support delta policies can then choose to use the deltas or the original list if they do not. When the PDPs support the delta policies we can remove the original list.

Probably want option 1, as there may be both deploys & undeploys in a single PDP_UPDATE.
