ONAP Dependencies

SDN-C depends on the following projects:

• Active and Available Inventory (A&AI)
• Common Controller SDK (CCSDK)

...

• .
• Service Design and Creation (SDC)

Architecture

High level architecture diagram

At that stage within the Release, the team is expected to provide more Architecture details describing how the functional modules are interacting.

Block and sequence diagrams showing relation within the project as well as relation with external components are expected.

Anyone reading this section should have a good understanding of all the interacting modules.

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

Third Party Products mean products that are mandatory to provide services for your components. Development of new functionality in third party product may or not be expected.
List the Third Party Products (OpenStack, ODL, RabbitMQ, ElasticSearch,Crystal Reports, ...).

In case there are specific dependencies  (Centos 7 vs Ubuntu 16. Etc.) list them as well.
