25、 060 V3.1.1 (2010-03)61 Scope The present document defines a specification based on DIAMETER for use at the Re Reference Point between the TISPAN NGN Generic-Resource Admission Control Function (x-RACF) and the Resource Control Enforcement Function (RCEF). Whenever it is possible the present documen

26、t 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. 2 References References are either specific (identified by date of publication

27、and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future chan

28、ges of the referenced document for the purposes of the referring document; - for informative references. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. NOTE: While any hyperlinks included in this clause we

29、re valid at the time of publication ETSI cannot guarantee their long term validity. 2.1 Normative references The following referenced documents are indispensable for the application of the present document.

49、IP packets in accordance with the filtering criteria received from the x-RACF. Policing of upstream and downstream traffic to ensure that the traffic remains within the authorized limits. The traffic policies are provided by the x-RACF to the RCEF through the Re reference point.
