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, as well as the Cloud CO Northbound API. Network Transport Protocols will be defined to carry the interface attributes. 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. This project is based on and will grow incrementally, 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

Contributions | Ding Hai (China Unicom) WT-413 Issue 2 | SDN Management and Control Interfaces for CloudCO Network Functions | 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. Mauro Tilocca (Telecom Italia) Tim Carey (Nokia) WT-435 | NETCONF requirements for Access Nodes and Broadband Access Abstraction | This project will develop the NETCONF requirements for the NETCONF/YANG Northbound interfaces (NBIs) of Access Physical Network Functions (PNFs) and the CloudCO BAA layer towards the Management and Control (M&C) elements that interact with them. | Contributions |

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:

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) |
