ONAP components need to talk with external systems such as VIM/VNFM/SDNC/EMS to orchestrate a network service, for example, SO/VF-C need to talk with VIM to allocate resource and VNFM to deploy a VNF. So they should get the information of available external systems from a registry before call the Interfaces of these external systems. ESR provides a service to centralized management of the information (name, vendor, version, acess end point, etc.) of external systems. So the ONAP components can get the system information with unified API from a logical single point.
Scope:
- This project provides a service to centralized management of external systems.
- Register/query/update/delete function of external system, such as VIM/VNFM/EMS/SDN Controller. Users can register/update/delete external systems to ESR with register API. And Multi-Vim/SO/VF-C, for example, can query and talk to external systems with the query API.
- Provide a portal to manage the external systems.
- Check whether the external systems are reachable, and store the health status.Provide a portal to manage the external systems So that other components can determine whether the systems are available based on the status.
Architecture Alignment:
- How does this project fit into the rest of the ONAP Architecture?
...
- How does this align with external standards/specifications?
- A&AI(store the external system data and status to A&AI)Multi VIM / SO / SDN-C
- MSB
- Are there dependencies with other open source projects?
