Hi Qiao,

Thanks for the interesting discussion around endpoint property for VNFs.

In terms of VNF migration and its impact on endpoint geo-location property design, I see there are two potential cases: inter-DC migration and intra-DC migration.
As you can see from the current design for endpoint geo-location property, the intra-DC migration might not be reflected by the current design unless we introduce something like server-id or rack-id?
But such information is too low-level I suspect and maybe considered sensitive or lose its practical meaning once the ALTO client is located outside the DC domain in question.
While within the DC, who would be the ALTO client for such information?

Regards,
Lingli

> Abstract:
>    This documentation presents a use case of Application-Layer Traffic
>    Optimization (ALTO) with the emergence of Network Function
>    Virtualization (NFV).  The Application-Layer Traffic Optimization
>    (ALTO) Service provides network information (e.g., basic network
>    location structure and preferences of network paths) with the goal of
>    modifying network resource consumption patterns while maintaining or
>    improving application performance.  The emerging NFV, which is
>    currently being in progress in ETSI NFV, leverages standard IT
>    virtualisation technology to consolidate many network equipment types
>    onto industry standard high-volume servers, switches, and storage.
>    The use case presented in this document discusses the impact of
>    virtualization on the ALTO protocol.  An architecture is proposed for
>    the interface between NFV MANO and ALTO server.  And possible end
>    point property extention is also discussed for such usecase.
