RE: Verbs or data model [was: Session reuse]

Some people (including myself) believe that passing all
of the notification delivery parameters each time the
session restarts is inefficient and bad SW design.
  - It also forces the manager to store all the parameters
    for every device, instead of giving them the option to
    use agent NV-stored data.
  - It forces all the NMS apps to share or duplicate this data,
    instead of having the option of storing it on the agent.
</Andy>
Two points on that:

1) I need to store a copy of my desired notification subscription
anyways because if configuration  doesn't exist I need to create it.
2) I am likely to be asking for the same information from all of my
devices. If they are stored on the device I then need to change them on
all of the devices. Much more work have to update those and then worry
about whether some other fool has the subscription configuration locked
or will step on my changes later on.

  - It forces the NMS and agent to replicate filter expressions
    instead of allowing them to be shared across applications,
    sessions, or even subscriptions.

You can use named profiles if you want to.
