2 Introduction and background to ODA A single framework that sets the vision and tools for IT and operating model fit for the 5G era ODA is is the TM Forum s proposal to enable richer and yet open, distributed digital collaboration with the essential tools to support increasingly demanding technical and commercial models. Technology progress such as:- 5G, AI, software defined networks, network virtualisation, SaaS (cloud ready, cloud native applications) are all driving OSS/BSS changes to simplify, automate and embed intelligence into the architecture. ODA, through platforms and APIs, provides: Business agility Lower cost of operation Support for flexible business models Eco-system capable Multi-vendor support Agile governance Ability to exploit the flexibility of the cloud The operating model of the digital enterprise demands Business decisions, product and service evolution and innovation driven by real-time data, analytics and artificial intelligence Continuous view of end-to-end customer experience & SLA adherence The latent value of digitalization to CSPs is estimated at more than $580 billion by 2026¹ CONTINUOUS IMPROVEMENT, DEVELOPMENT & INNOVATION (CI/CD) ¹ Source: TM Forum 5G Research Report, August 20 ² Source: Accenture, Ericsson & Arthur D.

3 Using ODA for internal alignment to manage hybrid infrastructure Benefits of Platforms within an overall Architecture ODA sub-divides the architecture into logical blocks or components to simplify the architecture, grouping related business functions into platforms and presents a transformation blueprint that enables architects and designers to approach the problem in a structured way. Loose coupling enables you to build the platforms independently of each other Define a standard means of communicating between platforms to minimise integration costs API hub/esb Identify a set of appropriate metrics to measure and track the progress of your transformation API s built, systems rationalised, cost reduced, time to market reduced, functionality delivered increased etc. Develop a standard enterprise data model (based on SID) to enable frictionless data transfers between platforms Determine what your core business services are (Open API s), and build them to support your standard business processes (etom) Data drive your product definitions and rules to ensure your architecture remains service agnostic to enable the management of hybrid environments 2018 TM Forum 3

4 Using ODA for internal alignment to manage hybrid infrastructure Digital enablement Becoming a digital service provider Digital efficiency Source: World Economic Forum Blue Ocean Opportunities e.g. 5G, IoT, B2B2x B2B Focus Red Ocean Battlegrounds e.g. Connectivity, Content B2C Focus $1.2tn Total industry additional profit * Should a company try and transform its internal systems for digital efficiency or start to build services that it can expose to enable it to participate in digital ecosystems, or do both? Digital efficiency continuously driving to improve the efficiency and scalability of the core business, from omnichannel customer centricity to automated network operation centers Digital enablement exploring how to enable new digital ecosystems, on board new partners and move into new markets from manufacturing, automotive and health to smart cities. Digital efficiency Analyze your processes, products and customers using business capabilities. Deconstruct your business using standard patterns identify duplication, inefficiencies, common requirements. Build solutions to use common services that drive re-use, optimize and simplify processes, rationalize systems enable rapid change through model, rule and data driven capabilities Digital enablement Identify which eco-system(s) you want to participate in and expose your services accordingly using Open API s to maintain loose coupling, tight integration and simplify partnership integration Observation The more mature and ubiquitous Digital Efficiency is throughout your organization, the easier it will be to deliver Digital Enablement 2018 TM Forum 4

5 Moving towards next-generation OSS for a virtualized and hybrid network Pattern matching and abstraction is key to simplification and automation Firewall vendors are implementing SDN enabled VNF firewalls. These expose a set command line interface (CLI) for managing the firewall. We are having to implement each vendors CLI in YANG/NETCONF to control the firewall. If we change firewall vendor we have to write new YANG/NETCONF. Legacy firewalls are managed differently through bespoke interfaces. Catalogue SDN Orchestrator ABCco YANG/NetConf for each firewall CLI XYZco YANG/NetConf for each firewall CLI Physical orchestrator YANG/Netconf version of CLI YANG/Netconf version of CLI ABCco CLI XYZco CLI Physical firewall SDN enabled ABCco VNF Firewall SDN enabled XYZco VNF Firewall We are seeing companies writing unique YANG/NETCONF for each vendors firewall Virtual infrastructure Virtual infrastructure 2018 TM Forum 5

6 Moving towards next-generation OSS for a virtualized and hybrid network Allows simplified management of hybrid network functions OSS solutions must conform to the abstracted definition of a standard set of firewall functions so that from the SDN controller we do not need to care which vendors firewall is providing the service. By wrapping the physical firewall CLI it can now be managed by the SDN orchestrator alongside SDN enabled VNF firewalls. Catalogue SDN Orchestrator ABCco functions for firewalls XYZco functions for firewalls Service to CLI translation implemented by vendor NaaS firewall functions Service to CLI translation implemented by vendor ABCco CLI Service to CLI translation implemented by vendor XYZco CLI Standard functions: Create firewall (firewall type) Close port (port num) Open port (port num) Open port restricted (port num, list IP addresses) Block IP address (list of IP addresses) Open port timeframe (open time, close time) Manage Port (Statefull packet inspection) Physical firewall SDN enabled ABCco VNF Firewall Virtual infrastructure SDN enabled XYZco VNF Firewall Virtual infrastructure Firewall vendors expose a standard set of functions that conform to industry standards for control and management of firewalls. Physical firewalls will be wrapped to support the same functions TM Forum 6

7 OSS & BSS Standards why the industry needs them, where we currently stand The position of TM Forum in the Standards Developing Organizations (SDOs) Business agility and interoperability Partnering for new services Simplification of the IT estate Reduced time to market By supporting an architecture based on modularity and reuse where capabilities are exposed through industry agreed Open APIs Enable new products and services to be created by providing services to, and consuming services from, other business units, subsidiaries and external 3rd parties from telco and increasingly other verticals By enabling systems rationalisation By enabling the configuration and reconfiguration of systems and capabilities through Open APIs to deliver new business solutions Drive digital business transformation through industrywide collaboration, experimentation and innovation Independent association with global membership, reputation and impact Extensive collaborative expertise and capabilities, with deep experience in Operations & IT Large global community with experts from across the telecoms landscape 2018 TM Forum 7

9 Integrating APIs in legacy environments and ensuring business continuity Transformation takes time and needs to be managed carefully Having reviewed your business strategy and identify the areas where change is required Using your platform based architecture identify the target solution that you want to implement, expressed in terms of platforms and capabilities exposed as Open APIs Build your new platform functionality, following the ODA patterns, and ensuring that the Open APIs can carry the relevant product or service payloads Wrap your legacy applications so that they can consume the relevant Open APIs Route transactions, based on your migration strategy (could be customer or product led) to the appropriate application within the platform When all transactions are routed to the strategic component switch off and decommission your legacy infrastructure This approach also simplifies your architecture as complexity is hidden behind the platform API interface 2018 TM Forum 9
