Hello all,

Following on from last week’s conference call and discussions, Tomohiro, Inder, Jerry, Chin and Vangelis and I have come up with a new proposal for advanced reservation in v1.0.  This is essentially a refinement on the existing proposal in the architecture document.

Some text describing this proposal is included in the attached document.

In essence this includes:

- 1PC

- All request require a pass/fail response from the Provider NSA

- Advanced reservation are supported with start time, end time, duration

- Times exchanged on the protocol reflect targets for the in-service time.

- It is the responsibility of the provider to achieve the start and end times.  This is done using guard bands unique to each provider NSA and are validated as constraints in path finding.

- Immediate reservation is supported with start time = asap

- Provisioning may be signalled by the requestor or local initiated by the provider

I would like to see if we can get consensus on this proposal in today’s call.

Regards,

Guy
