Questions from Architecture subcommittee to Usecase subcommittee

  1. Would the use case(s) require multi-site support?
  2. Would the use case(s) require multi-region/multi-domain/federation support?
  3. Would the use case(s) require Multi-national support?
  4. Do we need to consider enhanced networking features (e.g., underlays)?
    1. For the Enterprise vCPE use case, we already consider the enhanced networking features both underlays and overlays. For the underlay layer, we proposed two new components including PCE (Path Calculation Element) and NAI (Network Artificial Intelligence) which support new features of network management including traffic scheduling, QoS support and traffic prediction. For the overlay layer, we support three alternatives ways to set up connection between vCPE and the firewall on the edge of TIC-core, including VxLAN, IPSec and MPLS.
  5. Can individual use cases be built from same components? (common APIs/models)
    1. For the Enterprise vCPE use case, we can reuse the adjusted components from the Residential vCPE use case including multi-vim component, some of the VNFs and some parts of the infrastructure. In the E-vCPE use case, we may adapt different VNFs and also introduce some PNFs, as for the vCPE, those two use cases have quite different features.
  6. What are the challenges from the first set of use cases?
    1. Right now the SDN-C may not fully support the PNFs which may have different versions and adapt different models apart from YANG. So, we may have the needs to introduce 3rd-party controllers to configure the PNFs mentioned above. 
  7. What technical debt have you identified?
  8. Clarify business drivers and capabilities of the use cases
    1. For the Enterprise vCPE use case, it is mainly used for the Enterprise Service Provider (SP) to deploy enterprise-based vCPE to provide the Enterprise2DC service to the tenants both efficiently and safely. Enterprise users could receive high-quality and cheap cloud service based on the operator’s BSS Portal and ONAP. And in here, ONAP is used to instantiate and operate the required vCPE in the access network as a cloud service.
  9. What are the functional commonalities between the use cases? Are there generic elements where we should focus?
