Summary

This Recommendation specifies the functional architecture and requirements for the resource and admission control functions in Next Generation Networks, which may involve a variety of access and core transport technologies and multiple domains. The RACF provides real-time application‑driven and policy-based transport resource management in support of end-to-end quality of service (QoS), gate control, network address translation, and traversal of remote network address translators. The RACF is not service-specific. Services can make use of RACF whether the IP multimedia subsystem is involved or not.
