| Mission: The project stream's mission is to provide specifications and guidance for Cloud-based components used in the broadband network. The specification and guidance provided by this project stream help ensure that Cloud-based Components are multi-vendor and inter-operable. Critical elements of the work provided by this project stream is the support the transition from existing architectures toward Cloud-based architecture and alignment, when applicable, with various Cloud-based architectural frameworks such as Cloud CO. Business Impact: The work of this project stream creates the necessary architectural and interface specifications and associated guidance that enables a multi-vendor, inter-operable set of Cloud-based components that reduces the cost of development and deployment of Cloud-based components through standardized architectures, protocols, APIs and information elements. Projects: Specifically the project stream covers the following projects and their associated work products: - Automated Intelligent Management (AIM):

TR-436 | Access & Home Network O&M Automation/Intelligence | Over the past decade, growth in the Telco industry’s revenue has never outpaced growth in OPEX. As the scale of a network increases, OPEX increases with it. Therefore, it is expected that work needs to be done in order to reduce OPEX. This project will specify the logical framework of access & home network O&M automation, including necessary functional blocks, logical connection descriptions and information flows between the modules. In addition, this work will suggest possible applications of this framework to typical BBF service architectures. This identifies the information elements required in access & home network O&M automation, key use cases and KPIs, and analysis of the gaps with existing architectures to support these information elements. The project will describe what kinds of the information elements are required.

| This project provides a list of use cases with related high level requirements that provides a framework defining a new metro-compute networking architecture with in-depth integration of computing and network on top of the Cloud-based broadband networks, with the purpose of connecting isolated edge sites (e.g. Cloud CO) as one cloud to serve edge computing services, supporting the edge to edge collaboration, the edge to cloud collaboration, and load balancing among edge sites at network level. It includes recommendations for BBF Work Projects. |

| Description: Provides the architecture, requirements and interface specifications for a virtualized OMCI (vOMCI) solution that moves the OMCI functionality that is traditionally embedded within Optical Line Termination (OLT) network elements into the operator's Cloud-based network. The project supports various deployment models of the vOMCI solution where functions (i.e., OMCI translation function, OLT & ONU management functions) of the architecture can be deployed as a virtualized network functions and are expected to be used within Access domain SDN management and control solutions (e.g., Broadband Forum’s CloudCO) or as a stand-alone process that can be deployed with existing management system solutions.

| Description: FTTx represents today a high-cost technology (in terms of Return on Investments) to enhance data rates to the end customers, but it requires a huge effort, in terms of CAPEX and OPEX for access network deployment. Due to this, some operators have recognized the need to partner in order to improve the return on investment of FTTx deployment. Sharing the access network infrastructure is a viable way to expand the network and achieve an effective roll-out of new technologies. FANS delivers one network sharing model with high flexibility for forward looking broadband network deployments and operations, facilitating the business innovation, enhancing the network efficiency and improving customer experience. FANS also addresses the virtualization of that shared infrastructure such that each operator could have their own virtual access node. TR/WT/MR/MD/SD# | Projects | Abstract | | Editor(s) |

Bruno Cornaglia , Vodafone | MR-432 | Fixed Access Network Sharing | This paper examines the potential positive business and operational impact of Fixed Access Network Sharing (“FANS”). FANS enables broadband network infrastructure, and network management, to be shared amongst operators with resulting cost and standardization benefits along with the opportunity to handle a wider variety of service offerings. |

| MR-453 | Fixed Access Network Sharing (FANS) Technical Overview | Deep fiber deployments for ultra-fast broadband are technically challenging. Broadband Forum is defining Fixed Access Network Sharing (FANS), to offer a highly enhanced form of virtual unbundling of broadband access networks, enabling cost sharing and enhancing the dynamics of a competitive landscape. FANS automates and harmonizes data, control, and management interfaces among wholesale Infrastructure Providers (InPs) and retail Virtual Network Operators (VNOs). Standardized FANS interfaces can decrease operational expense (OpEx) while increasing customer satisfaction. FANS logically partitions and isolates network resources shared among the VNOs, and such sharing can split the cost of network upgrades among several entities. FANS works with virtualization, where control-plane functions are migrated from dedicated network equipment into software running on commodity hardware, with FANS providing Network as a Service (NaaS). This paper describes emerging Broadband Forum standards supporting FANS, use cases, FANS components, and details of the architectures supporting FANS. |
