The value of the SWVC Identifier Service Attribute is a string that is used by the Subscriber and the Service Provider to uniquely identify an SWVC. [R8] The value of the SWVC Identifier Service Attribute MUST be an Identifier String. [R9] The value of the SWVC Identifier Service Attribute MUST be unique across all SWVC Identifiers for SWVCs (SD-WAN Services) purchased by the Subscriber from the Service Provider.
[R9] requires that all SWVCs purchased by the Subscriber from a particular Service Provider have different SWVC Identifiers. For example, if the Subscriber has SWVC with identifier CorpIntranet with Service Provider X, it cannot have another SWVC with that identifier with Service Provider X. The Subscriber can have an SWVC with a different Service Provider with identifier CorpIntranet (although that would likely be a poor choice). Conversely, the Service Provider can agree to use the identifier CorpIntranet for three different SWVCs sold to three different Subscribers.
