Mission Statement:
This Work Area focuses on the introduction of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) in conjunction with general purpose hardware to create the basis for cloud-based, edge and access networks. Building on this framework, projects address migration and coexistence of physical and virtual elements, into the broadband network, define interfaces, test cases Use Cases and scenarios, reference implementations and automation. Activities work with and coordinate with Open Broadband (OB) program regarding open source, like Open Broadband-Broadband Access Abstraction (OB-BAA) and testing Open Broadband Laboratories (OBLs). Work Area Directors: Bruno Cornaglia (Vodafone) and Mengmeng Li (China Mobile)
Business Impact:
The migration to SDN and NFV in the broadband network facilitates agile deployment of new customized distributed broadband services and applications. This enables new revenues and provider differentiation while managing Capex and OpEx both in the access network and in single and multi-tenant residential and business locations by implementing an agile network and enabling autonomous and automated operations.
Scope:
The scope includes migration to and deployment of SDN/NFV-enabled implementations across all aspects of the broadband network. The scopes are:
- the definition of a new cloud-based environment with its related requirements, called Cloud-based Central Office (CloudCO)
- the architectural requirements, the interface specification among all the components with their related data models including the control-user plane separation interface for disaggregated access nodes
- the specification of virtual network functions and interface with their related data models
- the definition of requirements, interfaces and data models for autonomous and automated networks

This project stream is developing a next generation Central Office (CO) System that is part of BBF Open Broadband, which incorporates Software Defined Networking and Network Function Virtualization with SDN control & management running on a cloud-like infrastructure deployed at Central Offices. By ‘cloud-like’, it is meant that the infrastructure leverages commodity network switches and commodity compute nodes with virtualization software to host various virtualized network functions (VNFs). Infrastructure operators can offer these functions to 3rd parties and 3rd party network functions can be inserted into the platform, allowing Value Added Services. The goal of this project is building on the architectural framework for such a Cloud CO (TR-384), with appropriate abstracted functional modules, and interfaces, eventual API and protocol choices and/or definitions. The architectural framework allows interconnecting these functional modules in an interoperable manner. A secondary goal is to figure out and shows how standards organizations and open source projects can collaborate. This project will also establish a reference implementation of the Cloud CO framework, creating a platform for innovation and potential open source upstreaming into other organizations, as well as a platform for industry interoperability testing (OBL) and certification of NFs and the components that implement the aforementioned functional modules.

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:
Description: Enhance access and home networks with Cloud-based automation and intelligence, to achieve higher O&M efficiency and lower OPEX.
Description: Considers the Edge Computing impacts on multi-service broadband network, reference architecture, interfaces and to identify metro computing networking requirement,
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.
