Hi All, Please find the minutes for this week's NSI conference call here: http://forge.gridforum.org/sf/go/doc15974?nav=1 A summary of agreed features for rel 1.0 advance reservation is attached below. Guy Issue v1.0 status Comments Synchronization of Provider/requester timers? Required agreed NTP should be ok, but not mandated 1 or 2 phase commit? 1PC agreed 2PC is considered unnecessary for v1.0 Is automatic provisioning (initiated by timer) required? Yes agreed Is explicit provisioning (initiated by requester message) required? Yes agreed Is advance reservation required? Yes agreed Is immediate reservation required? Yes agreed May need to update architecture text Allow ASAP as start-time for immediate reservation? Yes agreed How is advance distinguished from immediate reservation? Immediate uses 'ASAP' in the start-time field agreed What does start-time mean as used in protocol for auto mode? In-service begin time agreed 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 agreed 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 agreed 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 agreed Is a tear-down signal required? Yes agreed 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 agreed This is a constraint in path finding Is a flag necessary to indicate immediate vs. advance reservation No agreed 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 agreed 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 agreed Does a reservation request require a pass/fail response from the Provider NSA? Response sent once reservation process completed. agreed Notification of provisioning?
