Summary

Recommendation ITU-T Y.2242 specifies a method of coordinating existing and ongoing works on service function chaining in mobile networks (specified in [IETF RFC 7665], [IETF RFC 8300] and [b‑ONF TS-027]) by introducing a chain orchestrator as a new entity.

NOTE – [b-3GPP TS 23.203] is another well-known specification on service function chaining.

Recommendation ITU-T Y.2242 also covers the case when relevant network functions are virtualized.

Recommendation ITU-T Y.2242 aims to describe the requirements, architecture, functional entities, reference points and information flows of service function chaining in mobile networks.
