[4] 发明背景 [4] Background of the invention
[5] 为方便本文的描述， 本文抽象出了通道、 资源管理器、 承载节点三个概念。 [5] In order to facilitate the description of this article, this paper abstracts three concepts of channel, resource manager and bearer node.
[6] 通道指的是用户设备与承载节点之间、 或承载节点与承载节点之间的物理链路 [6] The channel refers to the physical link between the user equipment and the bearer node, or between the bearer node and the bearer node.
、 物理接口、 逻辑接口或逻辑管道。 通道可以是物理上的链路， 如 X数字用户线 (x Digital Subscriber , physical interface, logical interface, or logical pipe. A channel can be a physical link, such as an X-digital subscriber line (x Digital Subscriber

wire, PW) 、 虚拟局域网 （Virtual Wire, PW), virtual local area network (Virtual
LAN, VLAN) 等； 通道也可以表现为物理接口， 如 xDSL端口、 无源光网络 （P assive Optical LAN, VLAN), etc.; channels can also be represented as physical interfaces, such as xDSL ports, passive optical networks (P assive Optical
Network, PON) 端口、 百兆以太网接口、 千兆以太网接口等； 通道也可以表现 为逻辑接口， 如各种物理接口的子接口等。 Network, PON) ports, 100M Ethernet interfaces, Gigabit Ethernet interfaces, etc. Channels can also be represented as logical interfaces, such as subinterfaces of various physical interfaces.
[7] 资源管理器可以为策略服务器 （Policy [7] Resource Manager can be a Policy Server (Policy

[8] 在现有技术中， 一段通道的带宽可以分别在资源管理器和承载节点上进行管理 [8] In the prior art, the bandwidth of a channel can be managed on the resource manager and the bearer node respectively.
。 在资源管理器上管理的带宽一般主要用于单播业务 （如视频点播业务等） ，
在承载节点上进行管理的带宽一般主要用于组播业务 （如宽带电视业务等） 。 对于同一段通道， 资源管理器可管理的初始带宽和承载节点可管理的初始带宽 是分别进行配置和管理的。 例如， 假设有两段通道， 通道 1的总带宽是 10M, 通 道 2的总带宽是 15M, 配置资源管理器可管理的通道 1的带宽为 8M、 可管理的通 道 2的带宽为 2M, 配置承载节点可管理的通道 1的带宽为 4M、 可管理的通道 2带 宽为 5M。 . The bandwidth managed on the resource manager is generally mainly used for unicast services (such as video on demand services, etc.). The bandwidth managed on the bearer node is generally used for multicast services (such as broadband TV services, etc.). For the same segment of the channel, the initial bandwidth manageable by the resource manager and the initial bandwidth manageable by the bearer node are separately configured and managed. For example, suppose there are two channels, the total bandwidth of channel 1 is 10M, the total bandwidth of channel 2 is 15M, the bandwidth of channel 1 that can be managed by the configuration resource manager is 8M, and the bandwidth of the manageable channel 2 is 2M.

现有技术的技术方案是通过分别对资源管理器和承载节点配置同一段通道可管 理的带宽， 容易产生资源管理器对该通道可管理的带宽与承载节点对该通道可 管理的带宽之和与该通道的总带宽不一致的情况； 例如上述通道 1可管理的带宽 之和为 12M, 而通道 1的总带宽为 10M, 通道 2可管理的带宽之和为 7M, 通道 2的 总带宽为 15M。 并且分别配置需要更多的人力投入， 从而增加了网络的维护成本 发明内容 The technical solution of the prior art is to configure the bandwidth manageable by the same channel in the resource manager and the bearer node respectively, and it is easy to generate the sum of the bandwidth manageable by the resource manager for the channel and the manageable bandwidth of the bearer node to the channel. The total bandwidth of the channel is inconsistent; for example, the sum of the bandwidths manageable by the channel 1 is 12M, and the total bandwidth of the channel 1 is 10M, the sum of the manageable bandwidth of the channel 2 is 7M, and the total bandwidth of the channel 2 is 15M.
