Summary

The architectural structure of a centralized resource admission and control functions (RACF) is considered in Recommendation ITU-T Y.2175. RACF is comprised of a transport resource control functional entity (TRC-FE) and a policy decision functional entity (PD-FE). This Recommendation defines an architecture, which considers a centralized RACF resulting from a centralized TRC-FE, specifies supporting requirements, and describes the resource reservation process for this specific architecture.
