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.

+ | 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: | ||
