ATP-069 Issue 2 | TR-069 Abstract Test Plan | ATP-069 provides a test plan that may be used to verify conformance of a CPE Device to the requirements defined in TR-069. | In force version: ATP-069 Issue 2 Corrigendum 1 | | DTP-181 Amendment 3 | CWMP Interoperability and Functionality Test Plan | In order to ensure the continued growth of the TR-069 market and further the interoperability of the protocol, the Broadband Forum is creating a TR-069 Certification Program. Within this program, devices implementing a TR-069 management interface may be tested for their conformance to the TR-069 specification and various use cases. The TR-069 Certification Program started with the TR-069 Conformance Test Plan and now the CWMP Data Model Implementation Test Plan. To provide a consistent scope for this verification, BBF developed these test plans that are to be used by the testing agencies in the verification process. This Internal Document provides a test plan that may be used to verify Interoperability of a CPE Device with an ACS Server through use cases. | Specification Kanban Board In force version: TP-181 Amendment 2 | | | DTP-469 | Conformance Test Plan for USP Agents | Testing is crucial to promoting the interoperability and adoption of standards. To meet this, the Broadband Forum regularly produces test suites that validate the conformance of implementations of their standards. This specification defines the test setup, test procedures, and test metrics to validate Agent and implementations of the User Services Platform (USP), published as BBF TR-369. This purpose of this document is to provide a definitive guide for validating the compliance of USP Agents in accordance with the specification. The tests defined below are intended to validate the specific requirements outlined in the USP specification, as well as those requirements defined in the Device:2 Data Model for USP Agents for objects, parameters, commands, and events necessary for the operation of USP. | Test Plan Bitbucket Kanban Board In force version: TP-469 Amendment 1 | |

Scope Operators are constantly looking for ways to make their operations more efficient and more cost-effective. A common method used is automation of the configuration and control of network elements. One challenge to doing this effectively is ensuring interoperability between network components of different vendors. The Common YANG Work Area addresses this challenge by defining YANG data models for functionality which is common across access network equipment of various physical layer technologies. - The prime objective of the Common YANG Work Area is the specification of YANG modules that are applicable to multiple Work Areas and/or involve expertise from multiple Work Areas.
- Next to this, it also maintains the BBF YANG Best Current Practices (OD-360), BBF-wide YANG processes, procedures and tools.
- In the future, Common YANG has the mission to specify NETCONF/YANG test plans and certification for the defined YANG modules.
The Work Area is also responsible for identifying YANG work in other SDOs that could or should be used by BBF YANG projects, and will work directly with such SDOs as and when appropriate in order to assist in meeting BBF requirements and timescales. Since its creation, Common YANG has published a series of YANG modules which meanwhile have become accepted by the wide industry: - TR-355: YANG Modules for FTTdp Management
- Defines YANG data models for the management interfaces to support FTTdp, in order to enable interoperability for FTTdp management
- TR-383: Common YANG Modules for Access Networks
- Defines YANG data models for the management of Broadband Forum specified access network equipment used across many deployment scenarios
- With these modules, service providers can efficiently manage a range of broadband services supported over any access technology, including VDSL, G.fast and Passive Optical Networks (PON).
- TR-374: YANG Modules for Management of G.hn Systems in FTTdp Architectures
- Defines a YANG Module for all standardized parameters and associated types for G.hn configuration, status monitoring, performance management, testing and diagnostics

CloudCO Project Stream
| Description |
|---|
| 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.

| TR-408 | Cloud CO Migration and Coexistence | This Cloud Central Office (Cloud CO) document provides guidance to Service Providers as they transform their existing Multi Service Broadband Networks (MSBN) toward a Cloud CO based network that is more adaptable, agile, scalable and dynamic than the existing MSBN, while reducing costs by retaining investments that the Service Provider has made in their MSBN. This document identifies considerations that Service Providers need to consider when determining the deployment strategy of either migrating the existing network or deploying a Cloud CO based network that coexists with the existing MSBN. It also provides transformation assistance by identifying approaches to migrating their existing MSBN and discusses when and how to introduce the Cloud CO infrastructure or leverage their existing IT infrastructure. Finally, the document provides examples of how functionality in the management, control and user planes can be migrated toward Cloud CO. | Contributions | Ding Hai (China Unicom) Tim Carey (Nokia) | TR-411 | Definition of interfaces between Cloud CO Functional Modules | This work will define the Interfaces between the Functional Modules in the Cloud CO Architectural Framework, as well as the Cloud CO Northbound API.

| TR-454 | YANG Modules for Access Network Map & Equipment Inventory | In a CloudCO architecture, the management of physical nodes requires interfaces to expose Access Network Map (ANM) and Equipment Inventory information to the SDN Management and Control and other CloudCO functional blocks. For the support of multiple tenants, it’s also useful to expose to Tenants only relevant ANM and Equipment Inventory information over the NB API. The project is defining YANG data models for ANM and Equipment Inventory applicable to the BAA layer and the Access SDN Management and Control. | Contributions | Yang Wenle Huawei Technologies Jie Chen CAICT | TR-477 WT-477 Issue 2 | Cloud CO Enhancement - Access Node Hardware Disaggregation | Operators want their networks to be adaptable, agile, scalable and dynamic, while reducing costs. Besides reducing CAPEX and OPEX, shortened time-to-market is much more desired. SDN and NFV in conjunction with general purpose hardware are two powerful tools that are exploited in the industry to optimize current networks. In BBF, the CloudCO re-architects the broadband network using the above mentioned technologies running on a cloud-like infrastructure, deployed at Central Offices. It encompasses the enabling work required for dramatically faster and more efficient provisioning of new revenue generating-services. On the other hand, Opensource organizations have a different life-cycle, focused on the implementation of reference features and using immediately available standards which can lead to incomplete, non-compliant and tightly integrated components. The scope of this project is to perform a gap analysis between Cloud-CO and Opensource solution(s) by defining the missing interface(s) between Disaggregated OLT and physical OLT. | Contributions | Issue 1

The project is defining YANG data models for ANM and Equipment Inventory applicable to the BAA layer and the Access SDN Management and Control. | Contributions | Yang Wenle Huawei Technologies Jie Chen CAICT | TR-477 WT-477 Issue 2 | Cloud CO Enhancement - Access Node Hardware Disaggregation | Operators want their networks to be adaptable, agile, scalable and dynamic, while reducing costs. Besides reducing CAPEX and OPEX, shortened time-to-market is much more desired. SDN and NFV in conjunction with general purpose hardware are two powerful tools that are exploited in the industry to optimize current networks. In BBF, the CloudCO re-architects the broadband network using the above mentioned technologies running on a cloud-like infrastructure, deployed at Central Offices. It encompasses the enabling work required for dramatically faster and more efficient provisioning of new revenue generating-services. On the other hand, Opensource organizations have a different life-cycle, focused on the implementation of reference features and using immediately available standards which can lead to incomplete, non-compliant and tightly integrated components. The scope of this project is to perform a gap analysis between Cloud-CO and Opensource solution(s) by defining the missing interface(s) between Disaggregated OLT and physical OLT. | Contributions | Issue 1

| TR-484 | Access Network Abstraction, Softwarization, and Disaggregation | This Technical Report specifies a Broadband Access Abstraction (BAA) Layer as part of a Software Defined
Access Network (SDAN) architecture capable of: - Seamlessly supporting a multi-vendor, multi-technology network of Access Nodes (AN)
- Connecting different designs of physical ANs, e.g., traditional chassis-based and disaggregated ANs
- Disaggregating Management Plane and Control Plane functions from the physical ANs and hosting
the functions on centralized or distributed NFVI locations
This Technical Report describes the key functional components of a SDAN architecture, specifies the BAA
Layer system and complements the family of Broadband Forum’s CloudCO specifications related to the access
domain (e.g., TR-384 [9], TR-411 [12], TR-413 [13], TR-435 [14], TR-451 [15], WT-477 [18]). | Contributions | Mauro Tilocca (Telecom Italia) | Application Notes |
| Application Notes (APPN) use the TR-384 framework to describe an implementable Use Case for a CloudCO 'application'. APPN includes Assumptions and Preconditions System Description using TR-384 framework (components) + Drawing Description of Actors Interactions, which describe what information gets exchanged between the TR-384 functional elements and what happens as a result after an actor performs an 'action' i.e., an API call at the CCO NB API or a user plane packet that enters the system. A ladder diagram shows the various interactions between the functional elements. Success Criteria for the interactions Various instances can be instantiated which detail a given implementation of the individual components
An Application Note Instance will then be created that details the exact components to be bootstrapped/installed onto an NFVI. ((i.e. it describes what VIM is chosen, etc, as well as e.g software releases etc). The APPN is then used to guide development of: | Application Notes Under Development | Application Notes and how they relate to other work Coordinated by PSL: Yves Hetoghs (VMWare) |

FANS MultiExcerpt named SDNpsfans was not found -- Please check the page name and MultiExcerpt name used in the MultiExcerpt-Include macro | WT-370, WT-386 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.

Jan Diestelmans (Nokia) | | 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. |

Ken Kerpez (DZS) | | 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. |
