Hi John,

I like your proposal for changes to the primitive and state names…. To me these seem more clear and consistent than previous versions.

Peoples,

Chin commented last week on the need for symmetry in naming for both operations and the state machine.  I dropped of the WG call this week when my mobile battery died, but I will assume a detailed discussion did not take place.  I did notice Guy changed the name of the cancel and release operation, so I thought I might bring up Chin's concerns again.  These are simple changes so I do not think they have much of an impact.  These are meant to line up the operations and state machine.

Here are the current operations and a proposed change:

Request a reservation:
reserveRequest -> reservationRequest
reserveConfirmed -> reservationConfirmed
reserveFailed -> reservationFailed

Terminate a reservation:
cancelReservationRequest -> terminateReservationRequest
cancelReservationConfirmed -> terminateReservationConfirmed
cancelReservationFailed -> terminateReservationFailed

Request provisioning:
provisionRequest
provisionConfirmed
provisionFailed 

Release provisioning:
releaseProvisionRequest
releaseProvisionConfirmed
releaseProvisionFailed

Request a Query:
queryRequest
queryConfirmed
queryFailed

And the current stater machine values:

Initial – nothing exist yet, the RA and PA are waiting the user initiation
Reserving –a reserveRequest has been sent and the PA is attempting to make a reservation
Reserved – the reserveRequest has succeeded and a reservation has been created
Provisioning – a provisionRequest has been sent and provisioning is ongoing
Provisioned (In-Service) – the Connection has been correctly provisioned
Releasing – a releaseRequest has been sent and a release is ongoing
Terminating (Canceling)– a terminateReservationRequest (cancelRequest) has been sent and a cancelation is ongoing

Terminated– nothing exists any longer, a cancel request has been successful

I think this might get us closer to what Chin is looking for...

John.

I have updated the NSI connection service protocol document to reflect the current discussions.  This is intended to incorporate both the NSI connection service protocol details and sufficient contextual discussion to allow this protocol to be implemented. There will no longer be an NSI connection service architecture document.

All feedback is welcome.
