Access Architecture (AA) Project Stream
Project Stream Leads: David Sinicrope (GM), Ericsson The project stream mission is to advance access broadband network architecture in traditional and new areas to ensure quality connectivity leading to quality user experience. Identify and document the key functionalities and relationships between entities to facilitate the transition of networks to encompass new practices such as virtualization while documenting the key functionalities that need to be brought forward to enable a seamless evolution path. A critical element of the work is the long term support of existing and new physical and statically management network elements alongside agile and virtualized functions in what effectively will be a stable hybrid network. This enables seamless migration based on market acceptance on new technologies, protection of existing infrastructure investment and normal spread of deployment in different territories. The project stream will focus on: The work creates the necessary foundation for all of the broadband network. It underpins new value-added services and application delivery for fixed access networks, for home and business that can now be deployed at the pace of each market. Co-existence of physical and virtualized solutions and from static and dynamic services will create a broadband network mitigating the risks to existing revenue and enabling market-paced migration. Drive evolution of the network to improve scale, resiliency, reliability and security. Specifically the project stream covers the following areas: The Architecture and Transport Architecture (ATA) Working Area (WA) has a rich history in defining various BNG architectures and requirements, from classic functions such as L2TP LAC to more recent functions such as Network Enhanced Residential Gateway (NERG) and Public Wi-Fi access in MS-BNG. The MS-Disaggregated BNG (DBNG) is an on-going project at ATA. TR-459 serve as a foundation document in defining the the architecture and requirements for a DBNG. Standardizing interfaces and protocols will ensure interoperability between various types of control planes and user planes deployments. One of the key objective TR-459 is to ensure the DBNG provides the same broadband service offerings as a classic MS-BNG. Compared to a classic MS-BNG, the MS-DBNG have several key advantages such as independent user plane and control plane scaling, independent control and user plane life cycle management, and centralized control plane for configuration. The separation of the control plane and user plane enables more efficient use of resources and simplifies operations. In addition, BBF is a forum that allows synergy amongst various work area and creates a unified vision for the broadband industry. An example of this is WT-459 the protocol selected for the State Control Interface (SCI) named, Packet Forwarding Control Protocol (PFCP). PFCP, a protocol defined by 3GPP in TS 29.244 for control and user plane separation (CUPS) communication, is used for 4G and 5G 3GPP architecture. In WT-458, CUPS for fixed mobile convergence, BBF again selected PFCP for the SCI. This is one of many examples of how BBF is providing a platform for all stakeholders to collaborate and create synergy across different Working Areas with a unified vision for Broadband. The DBNG project continue to define and study new architecture and new requirement of interest to service providers and vendors. DBNG YANG modeling, DBNG CG-NAT, and DBNG User Plane traffic steering are just some of the current working projects related to DBNG. New DBNG topics are encouraged to be brought to the ATA group through contributions, the following link provide the most up-to-date topics.

Work Area Overview
Mission Statement:
The Access and Transport Architecture (ATA) Work Area (WA) defines and specifies the architecture and equipment requirements for access, routing and transport network infrastructure. ATA produces industry-agreed specifications for applications such as mobile transport infrastructure (fronthaul and backhaul), data center interconnect, broadband Internet access, etc. as well as specifications for managing, testing, and maintaining these networks and their applications. This work typically takes the form of architecture, equipment requirements, test & implementation guidance, and education materials. Work Area Directors:
Business Impact:
A critical element of the work is the long term support of existing network elements alongside virtualized software based network functions, resulting in a stable network that may be evolved over time. This enables seamless migration of new networking technologies based on their market acceptance, at the same time protecting existing infrastructure investment, and deployment into new different territories. ATA specifications underpin the network infrastructure, value-added services and application delivery for fixed and mobile access networks, and allow deployment at the pace of each relevant market. Co-existence of physical and virtualized solutions for static and dynamic services create a network infrastructure mitigating the risks to existing revenue at the same time it leverages new networking technology according to market demand.
Scope:
ATA maintains the primary architectures for the work of Broadband Forum. The architectures, requirements and other deliverables reflect the control, management, and data plane aspects of the access, transport and routed networks used to provide operator, enterprise and “over-the-top” Internet based connectivity services. The deliverables of the work area are designed to leverage and integrate new industry technologies while protecting investment of current deployments. These deliverables provide the industry with a collective and consistent methodology to drive product development and service deployment.
