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?
