    • The embodiment of this invention discloses a method, a system and an apparatus for admission control of multicast or unicast. The method for admission control of multicast comprises: a network device receives a multicast request and executes admission control operation of multicast resources according to the multicast request; when multicast resources are not sufficient, the network device sends an outer resources request to a resources admission control device, and executes multicast operation according to the results of admission control operation returned by the resources admission control device responsive to said outer resources request. The method for admission control of unicast comprises: a resources admission control device receives a unicast resources request and executes admission control operation of unicast resources according to the unicast resources request; when the unicast resources are not sufficient, the resources admission control device sends an outer resources request to a network device; the resources admission control device executes unicast operation according to the results of admission control operation returned by the network device responsive to said outer resources request. The embodiment of this invention guarantees fast handoff of multicast service channel in the case of implementing resources share of multicast services and unicast services, and the implementation is simple.
    • 本发明的实施例公开了一种用于多播或单播接纳控制的方法,系统和装置。 组播接入控制方法包括:网络设备接收组播请求,根据组播请求执行组播资源的接纳控制操作; 当组播资源不足时,网络设备向资源许可控制装置发送外部资源请求,根据资源许可控制装置根据所述外部资源请求返回的准入控制操作的结果,执行组播操作。 单播接纳控制方法包括:资源准入控制装置根据单播资源请求,接收单播资源请求,执行单播资源的接纳控制操作; 当单播资源不足时,资源准入控制装置向网络装置发送外部资源请求; 所述资源许可控制装置根据所述外部资源请求,根据所述网络装置返回的接纳控制操作的结果来执行单播操作。 本实施例在实现组播业务和单播业务资源共享的情况下,保证组播业务信道的快速切换,实现简单。

    • A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.
    • 提供了一种用于管理网络资源的方法,设备和系统,涉及数据通信领域。 该方法包括以下步骤。 资源管理器(RM)根据接收的资源请求消息发送第一请求消息,以请求接入节点(AN)执行准入控制。 在接收到指示资源请求消息所请求的资源是否被允许的接纳控制结果之后,RM发送资源请求消息的响应消息。 因此,实现支持共享带宽的组播/单播连接准入控制(CAC),AN与宽带远程接入系统(BRAS,资源与准入控制子系统(RACS)之间的策略分配) 并保证BRAS;实现带宽资源共享,避免浪费带宽资源。
