1 Scope
The present document defines a specification applicable to the Rr interface between Generic Resource Admission
Control Function (x-RACF) instances, based on the Diameter protocol. Other alternative protocols which may also be
used for this interface such as ANCP are not specified in the present document.
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 Diameter. Where this is not possible, extensions to Diameter are defined
within the present document.
