2017-05-08: TR-383 Common YANG Modules for Access Networks

Tag: v2.0.0-TR-383

TR-383 defines YANG data models for the management of Broadband Forum specified access network equipment used across many deployment scenarios. Broadband Forum-specified access network equipment comprises Access Nodes and FTTdp DPUs. There is no assumption for BBF YANG modules to apply globally, e.g. to apply to access network equipment other than BBF Access Nodes and FTTdp DPUs, or to apply to core network equipment.

TR-383 YANG data models cover the following common areas (see TR-383 for a full listing of modules and submodules):

• DHCP
• Equipment
• Ethernet
• Layer 2 forwarding
• Interfaces
• PPPoE
• QoS
• Sub-interfaces
• Subscribers
• Types

Where appropriate, these YANG modules augment IETF YANG modules.
