WHY a flow matrix?
Numerous components are embedded in the ONAP architecture.
...
The main objective is then to authorize only pre configured flows on specific ports.
- Inter-components flows
All flows defined between components defined as project by ONAP.
...
The flows remain within the components .This would - ONAP project.
For instance for DCAE component, a flow between the collector (VES) sub_component and DCAE_lifecycle_manager.
WHEN a flow matrix?
A flow matrix should be established for each ONAP project.
It should be reviewd at each major release of the component.
HOW a flow matrix?
This may be too complicated to address all flows for a given project.
As a first step, external flows should be considered, and then the 2 other categories.
- a YAML file is available, in order to formalize the sharing of the information.: onap_matrix-flows.yaml
This file enables to provide information for each flow:
| Parameter | Value |
|---|---|
| name | name of the ONAP project e.g. DCAE. |
| sub_components: - name: | real name of the sub component e.g. dcae-snmptrap-collector |
| external_server_side: | in external server side list only ingress (external -> ONAP) traffic |
| type: | nodePort |
| external_communication: | N/A |
