A MEF SD-WAN Service has the following characteristics:

  • The Subscriber connects to the Service at an SD-WAN UNI.
  • The basic unit of transport at the SD-WAN UNI is an IP Packet.
  • The SD-WAN Service provides a layer 3, IP routed network2.
  • Ingress IP Packets at the UNI are segregated into Application Flows that can be based on the IP Packet data as well as the layer 2, 3, and 4 networking headers.
  • The SD-WAN Service supports policy-based autonomous traffic management.
  • The SD-WAN Service utilizes one or more Underlay Connectivity Services.
  • SWVC topologies are defined by Policies and IP forwarding constraints.
  • SD-WAN Services offer encryption between SD-WAN Edges.
  • Service quality objectives are based on the Policy applied to each Application Flow.
  • Application Flows can be blocked/discarded at an SWVC End Point by Policy.
  • Each Application Flow can, by Policy, be subject to a bandwidth commitment and limit. Members of an Application Flow Group share a single bandwidth commitment and limit.

  • Managed SD-WAN Services typically provide a Subscriber web portal and/or API with a dashboard of network health and performance and application information.

  • In a co-managed SD-WAN Service (management of the service is split between the Sub-scriber and the Service Provider), the portal and/or API can enable the Subscriber to modify aspects of the SD-WAN service such as defining Application Flows and creating/modifying Application Flow Policies.

  • SD-WAN Services align with the concepts of MEF LSO principles including Service Orchestration.



2 Layer 2 SD-WAN Services are out of scope for this document but could be covered in a future version of this standard or in another MEF standard.

    It would be good to include the MEF definition of the SD-WAN Service before listing the characteristics:


    "An SD-WAN Service provides a virtual overlay network that enables application-aware, policy- driven, and orchestrated connectivity between SD-WAN User Network Interfaces, and provides the logical con-struct of a L3 Virtual Private Routed Network for the Subscriber that conveys IP Packets between Sub-scriber sites."
