3 Signalling aspects

1 Scope

This Recommendation provides signalling architecture for control plane of distributed service networking
(DSN). Based on the functional architecture and the service provisioning in DSN, it specifies the mapping of
functions into PEs and the mapping of reference points to interfaces in DSN architecture when deploying
content service and multimedia telephony (MMTel) service over DSN. It also describes the protocols used for
interfaces and security considerations, etc.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 distributed service networking (DSN) [ITU-T Y.2206]: An overlay networking which provides
distributed and manageable capabilities to support various multimedia services and applications.

3.1.2 functional entity [ITU-T Y.2012]: An entity that comprises an indivisible set of specific functions.
Functional entities are logical concepts, while groupings of functional entities are used to describe practical,
physical implementations.

3.2 Terms defined in this Recommendation

None.
