Fixed 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 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. | Bruno Cornaglia, Vodafone | |||||||||

WT/MD/SD#CloudCo ProjectsAbstractRelated ContributionsEditor(s)WT-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,
vOMCI Interface Specification | The scope is to standardize the NBI and SBI of vOMCI function. The vOMCI function may support other administrative interfaces to modules (e.g., logging) to support non-OMCI related features, standardizing these interfaces are beyond the scope of this document. The vOMCI function is responsible for:
The OLT then would be responsible for:
Contributions | Tim Carey (Nokia) Zhang Dechao (China Mobile) WT-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 | WT-474 | Subscriber Session Steering | As Broadband Networks become more dynamic with SDN control and Cloud Central office, it is now possible to programmatically control which User Plane (UP) function each individual subscriber should be connected to. This creates many advantages for an operator to offer different service propositions to different customers. This project will define an architecture for Subscriber Session Steering, using the dBNG as an exemplary function. | Contributions | Jonathan Newton (Vodafone) Mach Chen (Huawei) WT-477 | 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.

APPN includes
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:

WT/MD/SD#SDN AIM ProjectsAbstractRelated ContributionsEditor(s)WT-436 | 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. Yue Sun (China Unicom) Ken Kerpez (ASSIA) |
