ITU-T Q.3312 (10/2010) i Recommendation ITU-T Q.3312 Use of the access node control protocol on the Rp interface Summary Recommendation ITU-T Q.3312 describes the use of access node control protocol (ANCP) on the Rp interface. It defines the associate
8、d signalling architecture, specifies the signalling flows required to support combined unicast and multicast admission control. It also specifies profiles of the ANCP and resource connection initiation protocol (RCIP), Recommendation ITU-T Q.3322, required for this task. Interworking between RCIP an
9、d ANCP is also specified in this Recommendation. History Edition Recommendation Approval Study Group 1.0 ITU-T Q.3312 2010-10-14 11 ii Rec. ITU-T Q.3312 (10/2010) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, inf
10、ormation and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a w
11、orldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down i
12、n WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication adm
13、inistration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory pr
14、ovisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attentio
15、n to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others ou
16、tside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the

ITU-T Q.3312 (10/2010) Introduction In some operators access network deployments,
20、 resource and admission control function (RACF) may not have direct access to a particular access node (AN-PE). This is not a problem for policy (which is typically simple and pre-configured by other means). However, it does require additions to the signalling architecture for resource control, as d
21、escribed in this Recommendation. In the current RACF architecture, the RACF manages the total bandwidth and dynamically assigns portions of bandwidth for unicast and multicast video traffic. In one possible arrangement, the traffic set aside for unicast traffic is managed by a top-tier TRC-PE, while
22、 the multicast bandwidth is managed by an instance of the TRC-FE implemented in the access node. As a result, the messaging to the access node passes via the Rp interface. The protocol initially defined for that interface was RCIP ITU-T Q.3322. For some access transport technologies, the preferred p
23、rotocol for control of the access node is the access node control protocol (ANCP). In order to allow use of ANCP at the access node and RCIP at the top-tier TRC-PE, this Recommendation specifies an interworking function within the EN-PE that interworks between the two protocols. It specifies other a
24、spects required to achieve the general goal of coordinated control of admission of unicast flows at the top-tier TRC-PE and of multicast flows at the access node. Such an arrangement minimizes response times for broadcast video channel selection by the user while providing centralized control over b
