2018-02-07 Meeting notes (SDN-R)

• Use cases:
  
  • Plug'n'play (device discovery)
  • Basics for FCAPS
• Week of June 25th - proposed
ONAP community lab at WINLAB "OWL" with remote access & inter-work with operators' and equipment vendors' labs
Decisions wrt resources, participation, and so on, approx. March 15
Joint with ONF (some sort of "officialized" collaboration between ONF and ONAP is being discussed)

The Broadband forum data model has defined objects and hierarchy using a generic device management principle. The objects could be stacked up as necessary to manage any HeNB/FAP device that provides service - CDMA2k, LTE, UMTS etc. It supports device discovery and management.

Adapting the broadband forum defined data model would help shorten the time taken to define a similar generic model in YANG to manage HeNB/FAP type devices. The intent in ONAP is to define a generic data model structure for device management and broadband form has done that work. Defining the BB forum data model in YANG format and writing a translation layer in Netconf for TR069 could accelerate a PoC for HeNB management.

TR181 data model:

The data model definition in this TR contains data model objects for basic device information, protocol stack configuration, network interface, routing, bridging etc. It also defines a baseline profile that specifies a minimum level of data model support. This data model represents Network interfaces and protocol layers modeled as independent data objects that can be stacked into whatever configuration a device might support.

TR196 data model:

This TR specifies the Data Model for Femto Access Point (FAP) and management of its various services (CDMA2k, LTE, UMTS, VoIP etc).
