Architecture - Migration

Mission Statement:

The Architecture and Migration Work Area defines the architecture of Broadband Forum's work. This identifies and documents 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.

Business Impact:

The work creates the necessary foundation for all of the work of the Broadband Forum. It underpins all the new value-added services and application delivery for fixed and mobile access networks, 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 hybrid broadband network mitigating the risks to existing revenue and enabling market-paced migration.

Scope:

The Architecture and Migration working area maintains the primary architectural models for the work of the Broadband Forum. The models reflect the control, management and data plane aspects of BBF defined architectures. The models are augmented to subsume new industry directions such as SDN and NFV while carrying forward key aspects of broadband as currently deployed. The products of the work area provide the BBF with a collective and consistent language and algebra to help drive overall consistency of product.

Working Texts

WT#	TITLE	Abstract	ALL CONTRIBUTIONS RELATED TO WT	EDITOR(S)
WT-317	Network Enhanced Residential Gateway	This Working Text specifies the Network Enhanced Residential Gateway (NERG) architecture. This architecture consists in shifting some of the functionalities of a residential gateway to the operator's network, for enabling network based features. The aim is to facilitate the deployment, maintenance and evolution of both existing and new capabilities without adding complexity to the RG and/or the home network.

WT-345	Broadband Network Gateway and Network Function Virtualization	Building on TR-101 and TR-178, WT-345 documents a set of architectures for broadband multi-service network, addressing infrastructures, topologies and deployment scenarios for Multi-Service Broadband Network Gateway (MS-BNG) with hierarchical instances realized as Virtualized Network Functions (VNF). Starting from such architectural models WT-345 defines the specific requirements necessary to support the addressed infrastructures, topologies and deployment scenarios, in order to fulfill the business requirements defined in TR-144. The main changes introduced in the WT-345 architectures compared to the TR-101 and TR-178 models are: - Implications of scale out - OAM and other Operational aspects - Traffic management and QoS	Click Here	Oliver Thorp, Sky plc
WT-349	DSL Data Sharing	This Working Text explores issues related to DSL data sharing and includes a standardized data model for DSL data sharing	Click Here	Peter Silverman, ASSIA Inc.
WT-359	A Framework for Virtualization	The purpose of this working text is to establish a framework to permit the Broadband Forum to effectively reference and specify systems such that the deployment of NFV (as defined by the ETSI NFV ISG) in Broadband Forum specified networks is facilitated.
