Unsupported Features
The SDX Release 6.4.x documentation set describes some features that are present in the code but that have not yet been fully qualified by Juniper Networks. These features will be fully tested and supported in a future release. We expect these features to operate as documented; however, if you use any of these features before they have been fully qualified, it is your responsibility to ensure that the feature operates correctly in your targeted configuration.
The following features are present but unsupported in this release.
IP Multimedia Subsystem (IMS)
IMS is a flexible network architecture that allows providers to quickly and cost effectively introduce rich multimedia services across both next-generation packet-switched and traditional circuit-switched networks. It uses open interfaces and functional components that can be assembled flexibly to support real-time interactive services and applications.
European Telecommunications Standards Institute (ETSI) created Telecommunications and Internet Converged Services and Protocols for Advanced Networks (TISPAN) to extend IMS support to fixed-line carriers.
In the TISPAN architecture, the SDX software provides a northbound Rq interface. It is a Diameter protocol-based interface that allows the SDX software to integrate with services found on the application layer of IMS.
