[Netconf] netconf call home connection type

[Martin Bjorklund <[e-mail]>]

Hi,

In draft-ietf-netconf-netconf-client-server-06, each "netconf-client"
in the "call-home" list has a list of endpoints and a
"connection-type".  The connection type defaults to "persistent".

I suggest we add a new connection type case "on-demand" or something
similar, which can be used e.g. when there is something external to
trigger the call home.  An example would be a periodic yang push
subscription.

I also suggest that the default connection strategy either is dropped,
or changed to "on-demand".


Also, looking at the "periodic" case, when have in ietf-netconf-server:

           |        +--rw periodic!
           |           +--rw idle-timeout?        uint16
           |           +--rw reconnect-timeout?   uint16

In YANG Push, we have:

           |  +--rw yp:periodic!
           |     +--rw yp:period         yang:timeticks
           |     +--rw yp:anchor-time?   yang:date-and-time


does it make sense to use similar parameters in these two cases (I
would then suggest to use period + anchor-time in both, but use a type
in seconds rather than timeticks).
