1 Scope
The present document provides a report on the study of the applicability of the ANCP protocol to the Rr interface
between Generic Resource Admission Control Function (x-RACF) instances.
Whenever it is possible the present document specifies the requirements for this protocol by reference to specifications
produced by the IETF within the scope of ANCP. Where this is not possible, extensions to ANCP are defined within the
present document.

x-RACF Generic Resource Admission Control Function
4 Overview
The present document describes the ANCP protocol for the RACS Rr interface. The Rr interface is used for QoS
resource reservation between x-RACF instances of RACS within a single administrative domain. The functional
requirements and the stage 2 specifications of the Rr interface are contained in ES 282 001 [i.1] and ES 282 003 [i.2].
