@Tracy Van Brakle

• Access to ONAP community lab at WINLAB "OWL"

Please register for the account by filling in the form at http://www.orbit-lab.org/userManagement/register and selecting

"Open Networking Foundation Wireless Working Group 3rd PoC"

as your group. This would eventually (you have 30 min to follow the link that you will receive after submitting the form) result in account creation.

Once account is created, you will have to follow the instructions for setting up your ssh access at:

http://www.orbit-lab.org/wiki/Documentation/bAccountManagement/DSSHConf .

With ssh configured, you can access 10.50 subnet in ORBIT by simply ssh-ing into gw.orbit-lab.org with your username and the set of keys you uploaded.

• Devices

BBF Model

Shanth

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.

Reference:

• https://www.broadband-forum.org/standards-and-software/technical-specifications/technical-reports

• https://www.broadband-forum.org/standards-and-software/technical-specifications/tr-069-files-tools

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.
