Hi Daniel, Thanks for the quick response :) We will check and get back if we have any further queries.
Apart from this, is the code flow from Network/ VNF adapter to OpenStack is correct as mentioned below? Also, we concluded that there is no Intermediate layer between MSO and OpenStack API calls i.e. OpenStack APIs are called directly from Network/ VNF adapter. Can you confirm my this understanding as well?

Currently, we are trying to understand how the OpenStack APIs are called from MSO for orchestration, and, if there is any intermediate layer in MSO which makes a decision about using the underlying Cloud platform, if there are more than one. However, as per our understanding currently only OpenStack is supported for now. Our current understanding is based on the MSO HLD available in ONAP wiki and static code reading. Following is what we understand and request community's comments on our understanding: Orchestration Request Flow in MSO - from Network/ VNF Adaptor onwards till OpenStack 1. MSO has Network adapter and VNF adapter which are used to create Virtual Network or VNF resources 2. Both Network adapter and VNF adapter call the OpenStack KeyStone and Heat APIs for authentication as well as service orchestration 3. Following are the major APIs (with filename) called to create Virtual Network or VNF resources MSO Network Adaptor createNetwork() ------------------------> createNetworkContrail() ------------------------> createNetwork() ------------------------> createStack()------------------------> OpenStack KeyStone & HEAT API calls NetworkAdapterRest.java MsoNetworkAdapterImpl.java MsoNetworkAdapterImpl.java MsoHeatUtils.java MSO VNF Adaptor createVfModule() ------------------------> createVfModule() ------------------------> CreateStack()------------------------> OpenStack KeyStone & HEAT API calls VnfAdapterRest.java MsoNetworkAdapterImpl.java MsoHeatUtils.java We would like to confirm our current understanding. Please provide your comments and suggestions on this. Also, currently we are not clear about the code from the MSO northbound Interfaces to Netwotk/ VNF Adaptor. So, any help on this as well is much appreciated. Thanks, Arun Arora
