Goals and Objectives Project(s): Technical Specification for SD-WAN Service Definition Purpose of the contribution: To describe the proposal and have an approval for the project Abstract: Definition of SD-WAN Service and its Attributes Motion: Yes. To approve the creation of this project

New Project Proposal Technical Specification SD-WAN Service Definition Joe Ruffles – Riverbed Tim van Herck – Velocloud October, 2017

Motivation There is currently no industry-accepted definition of SD-WAN Services. As the industry transitions to virtualized and software-defined technologies, and ultimately to ‘MEF 3.0’ Network as a Service, there is heightened industry attention on SD-WAN. Customers want the benefits of SD-WAN from a responsible party who can reliably deliver performant, secure, assured access to applications wherever they are hosted – in their own data center, a cloud provider, or elsewhere. To meet customer demand for agile, economical, end-to-end services and application delivery, Service Providers (SPs) need standards of capability and standards of inter-operator and multi-vendor interoperability. Having interoperability and quality standards will enable the industry to capitalize on the opportunities offered by this technology inflection point while underpinning innovation. Those SPs that can offer a service that is certified against a recognized industry standard will have a competitive advantage.

Scope Definition of SD-WAN Service functionality and related terminology Definition of SD-WAN Service components and placement into MEF 55 LSO framework SD-WAN Service Framework Functional components that are combined to create an SD-WAN Service, e.g. policy (e.g., QoS/Security/Business Priority) based forwarding by application or application type, dynamic path selection, security, transport (underlay) independent virtual overlays, etc. Description of Service Attributes for each functional component of an SD-WAN Service Non-normative use cases will be included

Broad Market Potential SD-WAN Technology and Services Market Poised to Reach $6 billion by 2020 (IDC) SD-WAN: Entry Point For Software-Defined Everything (Forbes) Spending on SD-WAN products will grow from $129 million in 2016 to $1.24 billion in 2020. (Gartner) SD-WAN-as-a-Service is appealing to end users and enterprises that don’t want to manage their WAN network or applications, and would prefer to outsource these services to a service provider. For service providers, SD-WAN-as-a-Service is viewed a new revenue opportunity. (SDxCentral)

Compatibility Leverage as appropriate and always remain compatible with LSO Reference Architecture (MEF 55) and ongoing work on IP Service Attributes. The SD-WAN Service specification will be developed in conjunction and cooperation with other MEF groups working on topics such as Intent Telemetry and Network Data Analytics (PNDA) Policy and Policy Defined Orchestration End-to-End Quality of Experience IP Service Attributes The SD-WAN Service specification work will inform and leverage these efforts, not duplicate them.

Distinct Identity Business Requirements and Use Cases for SD-WAN Service are being defined in the OpenCS SD-WAN group These will be formalized as the requirements for, and will form the basis of, the SD-WAN Service Technical Specification The requirements for SD-WAN Service touch many areas necessary for assured end-to-end Application Delivery, regardless of where the application is hosted These requirements include Traffic Steering, Policy, Assurance, Security, and WAN Optimization in addition to underlying basics of connectivity

Technical Feasibility This project aims to standardize and improve practices emerging in SPs. This project is a formalization of the work of the OpenCS SD- WAN group, comprising SPs and vendors, which is bringing the SD-WAN community together and defining common attributes. The SPs and vendors of the group believe that it is feasible. The recently published Understanding SD-WAN Managed Services white paper has already set the direction.

Deliverables Deliverable: a Technical Specification for SD-WAN Service that will include: Definition of SD-WAN Service, Service Components and Service capabilities (attributes) Builds on and formalizes the description the white paper Understanding SD-WAN Managed Services Describes, in greater detail, SD-WAN service capabilities such as Application Steering, Security, Policy, virtual overlays, and WAN Optimization Non-normative Illustrative Use Cases Demonstrates how the service addresses the different use cases SD-WAN Service Component Mapping to LSO Reference Architecture Shows how the the service components map into the MEF 55 LSO Reference Architecture.
