Notes from WSN-Policy 18 July

[Matthew I Roberts <matt.roberts@uk.ibm.com>]

All,

Here are the notes that I took from
the discussion of Policy proposals in yesterday's conference call;

David Hull re-worked proposal:
Used the discussion from the last conference
call to rework the proposal.
We might want to rephrase the wording
of the 'unconstrained' bullet in order to make it clear that we aren't
prohibiting other types of undefined behaviour, only suggesting what might
happen in this mode. For example changing "equivalent" to "similar
to".
In the "Atomic" bullet, stike
"all", so "before t0, notifications for the subscription..."

Managing message rates
diff between 5 per second and no less
than 0.2 seconds.
Peter wants more finegrained control
(ie not Integer as a second)
Rate vs minimum interval.
Discussion of sustained vs burst capacity
and whether we might be better to specify this property in those terms,
or in addition to the existing minInterval approach.
Boxcarring and how it plays into this
area.

Matt to provide alternative implementations
of sustained vs burst options.

NotificationTransformPolicy
Discussion of issue over what to do
if a multi element nodeset is returned from an expression. This will be
discussed further at the next conf call.
