The UNI is a reference point that represents the demarcation between the responsibility of the Subscriber and the responsibility of the Service Provider. As a result, at any given UNI there is only a single Subscriber and a single Service Provider.
This section includes the Service Attributes at each UNI which are summarized in the following table and described in more detail in the subsequent sections. Since an SD-WAN Service delivers IP packets between multiple Subscriber Network locations, much of this section is adapted from the UNI Services Attributes and UNI Access Link Service Attributes section of the MEF Service Attributes for Subscriber IP Services Technical Specification, MEF 61.1 [21] in order to achieve the greatest amount of commonality between MEF IP Services and MEF SD-WAN Services.
