 NFV infrastructure must be distributed across multiple geographical locations. This will require multiple connected OpenStack deployments,​ of different sizes. The infrastructure will also mix physical and virtual infrastructure. NFV infrastructure must be distributed across multiple geographical locations.

 === Uses Cases ===  === Uses Cases === 
 +
 +Sample Use Cases dealing with HA, GR:
 +
 +  - 1. HA: High Availability cross VIMs ( in one site, but not limited to). Requirements for such use case would relate to how Neutron establish the networks to support HA or how Keystone maintains HA features, for instances.
 +
 + 
 +
 +  - 2. GR: Geo-site Redundancy, with/​without application level data/​configuration replication (Cross-site disaster recovery would be one classic use case of this type). Requirements for such use case would relate to for example, how Cinder supports cross-site data replication.
 +
 + 
 +
 +  - 3. GLB: Geo-site Load Balancing, DNS based, or non-DNS based. GLB can work as the front-end for HA and GR, HA and GR can work without GLB.
 +
 +In the above exemplary use cases, VNF may run in active-active or active-standby mode, according to the VNF management setup, which is out of the scope of this project. This project only concerns with how VIM should support the VNF in multi-site scenario.
 + 
 +It should be noted that these are non-exhaustive exemplary use cases which aim to serve the purpose of the clarification of the project, in certain aspects that may have confusions .
 + 
 +More detailed use cases are among the targeted deliverables of phase 1 of this project, which won’t be available during the proposal period, and more sophisticated ​ use cases like migration across VIM could be discussed in the later phase.
  
 Currently there are several high level use cases already defined by ETSI NFV documents: Currently there are several high level use cases already defined by ETSI NFV documents:
