To help along the discussion on advance reservation I include a list of decision previously made by the group... Guy Issue v1.0 Comments 1 or 2 phase commit? 1PC 2PC is considered unnecessary for v1.0 Is automatic provisioning (initiated by timer) required? Yes Is explicit provisioning (initiated by requester message) required? Yes Is advance reservation required? Yes Is immediate reservation required? Yes May need to update architecture text Allow ASAP as start-time for immediate reservation? Yes How is advance distinguished from immediate reservation? Immediate uses 'ASAP' in the start-time field What does start-time mean as used in protocol for auto mode? In-service begin time It is the responsibility of the provider NSA to make sure that this in-service start time is met What does start-time mean as used in protocol for explicit mode? Time at which the provider is able to accept a provision signal It is now the requestor's responsibility to advance the explicit signal to ensure good in-service time. What does end-time mean as used in protocol for explicit mode? End of reservation What does end-time mean as used in protocol for advance reservation? In-service end time. This is the same as beginning of de-provisioning time Is a tear-down signal required? Yes Is connection duration required? May be required for ASAP start time Duration would replace end time. Is unspecified end-time allowed? No agreement on this point Provider validation of start time ? Validated This is a constraint in path finding Is a flag necessary to indicate immediate vs. advance reservation No Not necessary, immediate is indicated with 'ASAP' start-time. See flag below. Is a flag needed to indicate whether start-time later than specified guard is allowed? Yes These start times are treated as 'now' and warning may be sent back to the Requester NSA. Does each Connection request need a flag to indicate how to expect provisioning to be initiated? Yes, flag indicating provisioning method is required Does a reservation request require a pass/fail response from the Provider NSA? Response sent once reservation process completed. Notification of provisioning? Notification of provisioning completion is required.
