在欧洲电信标准协会 ( European Telecommunications Standards Institute , ETSI )电信和互联网融合业务及高级网络协议（ Telecommunications and Internet Converged Services and Protocols for Advanced Network, TISPAN )定义的下一代 网络（ Next Generation Network, NGN )架构中， 在应用层和传送层之间引入了 资源接纳控制子***（ Resource Access Control System, RACS ) , 用于统一管理 承载网的资源，并提供基于会话和策略的动态服务质量（ Quality of Service, QoS ) 控制。  In the Next Generation Network (NGN) architecture defined by the European Telecommunications Standards Institute (ETSI) Telecommunications and Internet Converged Services and Protocols for Advanced Network (TISPAN) A Resource Access Control System (RACS) is introduced between the application layer and the transport layer to uniformly manage the resources of the bearer network and provide dynamic quality of service (QoS) based on session and policy. ) Control.
RACS的功能架构如图 1所示， RACS主要包括： 业务策略决策功能实体 ( Service Policy Decision Function , SPDF ) 和接入资源接纳控制功能实体 ( Access-Resource Control Function, A-RACF ) , 其中,  The functional architecture of the RACS is shown in Figure 1. The RACS mainly includes: a Service Policy Decision Function (SPDF) and an Access-Resource Control Function (A-RACF), where
SPDF的主要功能包括： 釆用基于业务的策略规则进行策略决定： 接收应用 功能实体 （Application Function , AF ) 的资源请求并根据本地策略， 以及与 A-RACF和边界网关功能实体（Border Gateway Function, BGF ) 的交互结果对 AF发出的资源请求进行授权；  The main functions of SPDF include: 策略 Policy decision based on business-based policy rules: Receive resource requests from Application Function (AF) and according to local policies, and with A-RACF and Border Gateway Function (Border Gateway Function, BGF) interaction results authorize resource requests issued by AF;

目前 RACS中定义的 QoS监控点有三个： 第一个， 是 BGF, RACS通过 la接口 下发流策略， 控制 BGF完成该点的 QoS控制功能； 第二个， 是 RCEF, RACS根据 接入网的拓朴结构和资源使用情况， 决定是否允许新的会话接入， 并通过 Re接 口下发流策略， 控制 RCEF完成 QoS控制功能； 第三个， 是 AN, RACS通过 Ra接 口控制 AN完成 QoS控制功能。  At present, there are three QoS monitoring points defined in the RACS: The first one is the BGF. The RACS sends the traffic policy through the LA interface to control the BGF to complete the QoS control function of the point. The second one is the RCEF, and the RACS is based on the access network. The topology structure and resource usage determine whether to allow new session access, and control the RCEF to complete the QoS control function through the flow policy of the Re interface.
