DescriptionPS LeadershipCloud in the Central Office
(Cloud CO)

This project stream proposes developing a next generation Central Office (CO) System that aligns with the BBF Broadband 20/20 vision, which incorporates Software Defined Networking and Network Function Virtualization, running on a cloud-like infrastructure deployed at Central Offices.

By ‘cloud-like’ 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 to provide an architectural framework for such a Cloud CO, 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

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 and certification of NFs and the components that implement the aforementioned functional modules.

DescriptionPS LeadershipFixed Access Network Sharing (FANS)

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 RoI of FTTx deployment.
Sharing the access network infrastructures 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.

    Cloud in the Central Office
    (    Cloud CO)


    Leadership:

    Haomian Zheng , Huawei

    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-408Cloud 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.

Furthermore the data models, schemas or APIs that are signaled across them will be defined as well.  Existing Open Interface works, as described in Standards and Open Source work will be leveraged as much as possible. 

    It is foreseen that this work

    This project is based on and will grow incrementally,

    based upon

    driven by a series of Cloud CO Application Notes (APPNs).  Cloud CO Application Notes will detail how a certain service is instantiated, maintained and consumed across the Cloud CO Architecture and will detail the necessary interactions between the different Functional Modules in the Architectural Framework, as well as the interactions with the

    In the Cloud CO context, WT-413 specifies the management and control framework of Network Functions and a formalism to specify their NBIs to identify the supported macro functionalities and link them to existing/to-be YANG DMs. This work primarily enables the migration from SNMP/MIB towards NETCONF/YANG interfaces and potentially other protocols to exercise not only traditional FCAPS management functions but also fine grained flow control across VNFs and PNFs network service graphs. This is a key step towards Software Networking introduction and in turn the automation and Orchestration of PNFs and VNFs in a Cloud CO type of architecture.

    The development of this Working Text shall also shape the thinking on the way Cloud CO interfaces, especially for VNFs, are modeled and the opportunity to reuse/extend existing YANG work for that.

    WT-416Use Cases and Scenarios for Cloud Central Office

    This CloudCO document complements the CloudCO architectural framework specified in TR-384 and it helps drive a key element of the BBF's strategy in enabling new revenue generating-services, which is articulated in the Forum's Broadband 20/20 vision. It encompasses the Existing Broadband Scenarios used to support the CloudCO architectural framework design and as well the Use Cases that are established using this CloudCO architectural framework.  

    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. Software Defined Networking (SDN) and Network Function Virtualization (NFV) in conjunction with general purpose hardware are two powerful tools that are exploited in the industry to optimize current networks.

    WT-370FANS Overall Architecture and RequirementsFANS Overall Architecture and Requirements investigates on the technical aspects associated with Fixed Access Network Sharing (FANS), which covers the Access Network and part of the Customer Network in case of PON architecture, addressing the typical infrastructures, topologies and deployment scenarios. It also provides security considerations necessary to support multi-operator access sharing. This project outlines technical aspects related to the migration of TR-101 and TR-178 based architectures toward a shared converged broadband access network architecture that supports the business drivers defined in SD-351. Besides multi-operator sharing scenarios, this project can be also appropriate for a network operator that wants to slice its access network to offer different services toward customers (e.g., for residential or enterprise markets) and wants to be able to manage it using a vertical organization structure. Furthermore, FANS Overall Architecture and Requirements is the ongoing pilot project for the upcoming activities related to Access Network Sharing interface(s) and SDN-Enabled FANS.JIRA contributions

    Fixed Access Network Sharing (FANS) Business Overview

    This paper discusses this evolution and the potential impact of Fixed Access Network Sharing (FANS) for those interested in business-related aspects. FANS enables broadband network infrastructure, and network management, to be shared amongst operators; thus sharing the costs of gigabit-class broadband deployment while enabling operators to run their own operations. Compared with deploying multiple parallel networks, FANS can lower capital costs. (previously listed as MD-426)Jira Contributions

    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.

    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.

    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:

    • Interface Descriptions (WT-411)

    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.

    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.

    MultiExcerptNameFANS_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.

    MR-432Fixed Access Network SharingThis 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-453Fixed Access Network Sharing (FANS) Technical OverviewDeep 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.

    		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. TBA
