The SD-WAN Service Attributes and Services Standard defines the externally-visible behavior of SD-WAN Services. The Service description is based on an agreement between an SD-WAN Subscriber (the buyer) and an SD-WAN Service Provider (the seller) that includes agreement on the values of a set of SD-WAN Service Attributes defined in this document.
This document includes:
SD-WAN Service Attributes – i.e., the enumeration and description of the information that is agreed be-tween the SD-WAN Subscriber and the SD-WAN Service Provider. The values of these Service Attributes are determined by agreement between the Subscriber and Service Provider, subject to constraints imposed by the Service description. Rigorous definition of Service Attributes also facilitates information modeling for API and protocol definitions.
SD-WAN Service Framework – A framework for defining instances of an SD-WAN Service based on the definitions, service elements, and Service Attributes included in the document.
It is important to distinguish between the SD-WAN Service and the Underlay Connectivity Services over which the SD-WAN operates. An SD-WAN Service Provider provides the SD-WAN Service to the Sub-scriber. The SD-WAN Service Provider may provide one or more of the Underlay Connectivity Services, but some or all of them may be provided by the SD-WAN Subscriber or other Service Providers.
