Description

捆绑链路的配置处理、 配置方法及装置 技术领域 本发明移动通信领域, 更具体地说, 涉及一种捆绑链路的配置处理、 配置方法及 装置。 背景技术 随着宽带网络的大规模普及、 互联网业务类型日新月异式的增长, 以及业务质量 的不断提升, 用户带宽需求的飞速增长, 电信运营商的宽带接入网络面临是越来越大 的负载压力, 运营商的带宽扩容速度已经渐渐跟不上宽带用户的需求增长速度, 同时 由于用户使用习惯、 作息时间等等的多样性越发明显, 传统的根据新增用户数扩容的 方式成本巨大、 已经不能满足网络发展的需求。 宽带网络的发展需要依靠更大范围的资源共享来实现资源的有效利用, 而非盲目 的物理带宽资源。传统的宽带网络中, 网络带宽的规划是根据用户数量, 实现小区级、 小局点的带宽资源共享, 包括线路带宽资源和业务节点带宽资源, 从目前的网络发展 速度来看, 线路带宽资源相对业务节点带宽资源而言相对比较充足, 而后者明显已经 遇到较大的资源困境, 一个很有代表性的问题就是, 大部分用户在晚高峰时段都无法 享受到运营商承诺的最大带宽, 原因是这段时间内大部分的用户都集中在城市的居住 区, 居住区的业务节点的带宽资源使用率极高, 而城市办公区的业务节点普遍处于较 低使用率、 甚至闲置状态。 反之, 工作时段城市居住区的宽带网络设备的资源利用率 远低于晚高峰时段。 如何解决宽带网络的资源利用效率问题, 进而实现最大限度的利用现有的网络资 源、 降低扩容频率、 减少网络成本投入, 这是当前全球电信运营商面临的主要问题之 一。 在宽带接入领域, 尤以提升业务节点 (即宽带接入服务器、 业务路由器等设备) 的资源利用率为主要需求。 当前业界的主流技术方案是业务节点的池组化方案, 通过 更大范闱的业务节点资源共享, 实现全天候、 大规模地区的宽带资源合理利用, 在有 限的资源下实现不同地区的峰时谷时的资源互补、 不同类型的用户的资源共享。 就业务节点的资源池组化技术方案而言,首先要实现不同业务节点间的用户信息、 网络信息的资源共享, 当前主流的方案是业务节点间的分布式协商, 就所谓 Full Mesh (全互联) 方式实现业务节点间的信息全共享。 但这种方式随着资源共享的规模越来 越大, 必然带来连接数量巨大、 难以管理的问题, 新增、 删除一个业务节点必然导致 全网的配置变更, 存在扩展性难、 管理难度大的问题。 针对相关技术中, 在资源共享模式中, 网络资源利用率低以及易出现链路故障的 问题尚未提出有效的解决方案。 发明内容 本发明实施例提供了一种捆绑链路的配置处理、 配置方法及装置, 以至少解决相 关技术中, 在资源共享模式中, 网络资源利用率低以及易出现链路故障的问题。 为了达到上述目的, 根据本发明的一个实施例, 提供了一种捆绑链路的配置处理 方法, 包括: 接收网络内业务节点的设备信息和 /或接入链路的接入用户信息, 其中, 所述接入链路为所述网络内的汇聚设备与所述业务节点之间的链路捆绑组中的链路; 判断所述设备信息和 /或所述接入用户信息是否满足预设条件; 在满足所述预设条件 时, 向所述汇聚设备发送用于调整所述链路配置方式的调整指令。 优选地, 判断所述设备信息和 /或所述接入用户信息是否满足预设条件, 包括: 判 断所述设备信息和 /或所述接入用户信息是否满足以下至少之一条件: CPU利用率大于 或等于阀值、 内存利用率大于或等于阀值、 接入链路用户数量或用户总带宽大于或等 于最高阀值、 接入链路用户数量或用户总带宽小于或等于最低阀值、 上行链路故障、 下行链路故障、 线卡故障; 其中, 在满足以上至少之一所述条件时, 判定需要调整所 述链路配置方式。 优选地, 所述设备信息包括以下至少之一: CPU状态、 内存状态, 上行链路状态、 所述接入链路状态、 整机负载信息、 链路负载信息、 线卡状态。 优选地, 所述接入用户信息包括以下至少之一: 所述接入链路的用户数量、 用户 授权信息、 用户带宽信息。 优选地, 所述调整指令中携带有以下至少之一调整策略: 停止指定接入链路的用 户接入、 停止指定接入链路的新用户接入、 将指定接入链路的接入用户切换到另一接 入链路、 调整指定接入链路的主备或负载分担的优先级、 调整指定接入链路的媒体接 入控制 MAC地址数量限制。 优选地, 上述方法还包括:在将指定接入链路的接入用户切换到另一接入链路时, 将所述接入用户的用户信息发送至与所述另一接入链路的业务节点。 优选地, 接收网络内业务节点的设备信息和 /或接入链路的接入用户信息之前, 还 包括: 接收来自所述汇聚设备的当前链路配置方式。 优选地, 所述链路配置方式包括以下至少之一: 多个所述接入链路的主备方式、 多个所述接入链路的负载分担方式。 优选地, 所述业务节点包括以下至少之一: 宽带远程接入服务器 (Broadband
