1 Scope
The present document aims at providing recommendations for the introduction of autonomics (management and control
intelligence) into the fixed broadband access and aggregation networks specified in the Broadband Forum (BBF)
Architecture specifications. To this effect, it covers the instantiation of the reference model for Autonomic Networking,
Cognition and Self-Management, called GANA (Generic Autonomic Networking Architecture) [i.1], starting from the
reference architecture defined in BBF TR 101 [i.6], and considering also BBF TR 178 [i.7] and BBF TR 317 [i.28]
reports. It superimposes GANA Decision Elements (DEs) into nodes/devices and the overall BBF network architecture,
so that the DEs and their associated control-loops can be further designed to perform autonomic management and
control of the specific resources (Managed Entities) in the target architecture.
Based on this, the present document identifies the requirements for autonomic behaviours (Autonomics Functions/DEs)
across the fixed broadband access and aggregation network segments of the BBF reference architecture and provides
recommendations on where and how the GANA Functional Blocks (including DEs) should be instantiated. It further
extends these recommendations to the virtualized manifestation of these segments considering their virtualized
evolution in conjunction with SDN and NFV technologies. Finally, it also provides recommendations on the
interworking and coordination between autonomic functions among GANA-BBF and GANA-3GPP (Core Network)
domains, as well as recommendations on the Interworking and coordination between virtualized GANA-BBF and
virtualized GANA-3GPP (Core Network) domains.
