Meanwhile, the MEF has definesd an SD-WAN service and its various attributes. With strong support from service provider and technology provider members, MEF currently is on track to ratify and publicly release its MEF 3.0 SD-WAN Service Attributes and Service Definition standard in 1Q 2019. SD-WAN service standardization will enable a wide range of ecosystem stakeholders to use the same terminology when buying, selling, assessing, deploying, and delivering SD-WAN services. The SD-WAN service definition is a foundational step for accelerating sales, market adoption, and certification of MEF 3.0 SD-WAN services orchestrated across a global ecosystem of automated networks.

SD-WAN Service Standardization
SD-WAN service standardization is being conducted within the context of the MEF 3.0 Global Services Framework. It is part of a transformational initiative to standardize a complete family of dynamic Carrier Ethernet (CE), IP, Optical Transport, SD-WAN, security, and other virtualized services that will be orchestrated over programmable networks using LSO (Lifecycle Service Orchestration) APIs.

MEF’s SD-WAN service definition specification describes requirements for an application-aware, over-the-top WAN connectivity service that uses policies to determine how application flows are forwarded over multiple underlay networks irrespective of the underlying technologies.

“MEF’s groundbreaking work in standardizing an SD-WAN service addresses one of the biggest obstacles impacting SD-WAN service market growth,” said Nan Chen, President, MEF. “In a recent joint MEF and Vertical Systems Group survey of service providers worldwide, nearly 80% of respondents identified the lack of an industry-standard service definition as a significant challenge for service providers to offer or migrate to SD-WAN services. MEF’s SD-WAN service standardization will undoubtedly accelerate sales of SD-WAN products and services like MEF accomplished with Carrier Ethernet service standardization.”

Just as the industry has benefited from MEF standardization of CE services – which now exceed an estimated $50 billion in annual revenues globally – there are numerous potential benefits associated with a common SD-WAN service definition. These include, among other things:

• Reducing market confusion about service components, core capabilities, and related concepts, thus saving valuable time given the scarce availability of skilled personnel.
• Enabling service providers and technology providers to focus on providing a core set of common capabilities and then building on that core resulting in differentiated offerings.
• Facilitating inclusion of SD-WAN services in standardized LSO architectures, thereby advancing efforts to orchestrate MEF 3.0 SD-WAN services across multiple providers.
• Paving the way for creation and implementation of SD-WAN services certification, which will give users confidence that a service meets a fundamental set of requirements.

SD-WAN Implementation 
MEF member companies are involved in multiple SD-WAN implementation-related initiatives that can be leveraged to provide feedback on standardization requirements and create software-oriented artifacts that can be used to accelerate efforts to orchestrate standardized SD-WAN services. These initiatives include the MEF 3.0 Multi-Vendor SD-WAN Implementation project, the MEF18 LSO Hackathon, and several SD-WAN Proof of Concept (PoC) demonstrations at MEF18.

The MEF18 LSO Hackathon is focused on developing and validating data models for SD-WAN services. This presents a unique opportunity for those involved in technical aspects of SD-WAN services and products to learn in a hands-on way about the latest SD-WAN service and LSO standardization work at MEF as well as the related API and YANG work at ONF and IETF.

Three MEF18 PoC demonstrations directly related to LSO-enabled orchestration of SD-WAN services include:

• Zero Touch Services with Secure SD-WAN
• Towards a Multi-Vendor Orchestrated SD-WAN – LSO-enabled Solution with Open Source Orchestrator and Container-based uCPEs
• Instantiation and Delivery of SD-WAN over a Virtualized and Orchestrated Wholesale Carrier Ethernet Access Service.

MEF 3.0 SD-WAN Service Certification
MEF currently plans to introduce a pilot version of certification for MEF 3.0 SD-WAN services in the first half of 2019. This certification will test a set of service attributes and their behaviors defined in the upcoming SD-WAN standard and described in detail in the MEF 3.0 SD-WAN Service Certification Blueprint.
