HEADLINE TEXT TO BE PLACEDWhere are my resources located?
IT Cloud Carrier Cloud
Typically in cloud scenarios, there are no requirements on the resource topology. However, in NFV scenarios
there could be situations where CPU, memory and I/O devices should be requested not only in terms of number, but also in terms of proximity. For this reason,
we need the NFVI server to expose the full topology of resources and their availability.
The idea is to describe the resource topology in such
a way that an appropriate assignment of resources can be made by the orchestrator in order to guarantee that the VNFC will achieve a predictable performance.

80%%%% of voice call is local and most of call is between LTE and 2G/3G/PSTN in LTE initial phase.

event and automatically suggest a new deployment of S/PGW on a data
center which is closer to end users.

HEADLINE TEXT TO BE PLACEDWhere are we currently?
� VNF/NS Template can specify the DC for VNF deployment.� VNF/NS Template may use “Affinity” for HA model.
� Proprietary solutions exist, which leads to multi-vendor issues.
� Dynamic network information like mobility and congestion status is not currently communicated to MANO.
� Session continuity for on-demand VM placement needs consideration.
� In ETSI NFV standard, multi-DC VNF deployment has not been
discussed.

“We're going to march to 4 600 data centers, that's how many central offices we have. That would be what allows us to take advantage of our architecture and
then the microseconds of compromise that exist between the matter and the application will be overcome by the milliseconds we avoid by having an extremely highly distributed, very fast fiber network.”
