Subcomponents of each ONAP project may be found on the Resources and Repositories (Deprecated) page on this wiki. Please see the SDNC section of that page for subcomponent list of SDNC.
ONAP Dependencies
SDN-C depends on the following projects:
- Active and Available Inventory (A&AI)
- Common Controller SDK (CCSDK).
- Service Design and Creation (SDC)
- Data Movement as a Platform (DMaaP)
- Documentation
- Integration
- External API
- Modeling
- Multi VIM/Cloud
- Policy
Architecture
High level architecture diagram
CCSDK is delivered as a set of libraries accessible as Maven dependencies, as well as a set of base Docker containers. The docker containers themselves are intended to be used by other projects as a basis for their own controller-specific docker containers.
The following diagram illustrates how CCSDK is used by the controller projects:
The following diagram shows the high level architecture of SDNC:
The major architectural components of the SDN-C controller are:
- Device Data Models : Yang models that define interfaces to devices (virtual or physical) that the SDNC configures
- Service Network Data Models : Yang models that define data maintained within the SDNC about the network used by the set of services supported by this SDNC instance
- Service Chain Data Models : Yang models that define how services supported by an SDNC instance can be chained
- Service Data Models : Yang models that define data maintained within the SDNC for the set of services it supports
- Directed Graphs : programmable logic, updatable at run time with no restart, that define the behavior of the SDNC
- Service Logic Interpreter : module provided by CCSDK which allows platform to execute directed graphs
- API Handler : code (mostly generate from service Yang models) which implements RESTCONF API into SDNC. Most API handlers should follow the following pattern:
- Call directed graph named after invoked RPC, passing RESTCONF RPC parameters as Java Properties object.
- Return results from directed graph invocation as response to RESTCONF RPC
- Interface adaptors - code that allows directed graphs to invoke external interfaces
