Description

一种基于实际业务应用场景的 VDSL2配置管理模型 技术领域 本发明涉及宽带通信领域, 具体而言, 涉及一种基于实际业务应用场景 的 VDSL2配置管理模型。 背景技术 第二代甚高速数字用户环路 ( Second Generation Very-high-bit-rate Digital Subscriber Loop, 筒称为 VDSL2 )是一种基于铜缆的高速宽带接入方 式, 高速带宽是建立在高频信号传送的基础上, 而高频信号在铜缆中传输时, 对接入线路的噪声、 衰减等因素会艮敏感, 而这些因素的外在表现就是铜缆 的线径、 长度、 噪声等外在环境因素。 在 VDSL2 的配置参数中, 有些参数 就是 3艮这些环境因素密切相关的。
VDSL2 是电信宽带接入领域下一代数字用户环路 ( Digital Subscriber Loop , 筒称为 DSL ) 的接入技术。 相关技术中, "宽带论坛" (原名 "DSL 论坛 " ) 已经定义了 VDSL2线路管理的模型, 包括配置管理模型, 相关的技 术标准是: 数字用户环路讨论技术报告: 应用于下一代数字用户环路技术的 TR-129 独立保护管理模式 2006年 12月 12 日( DSL Forum Technical Report: TR-129 Protocol-Independent Management Model for Next Generation DSL Technologies, 12 December 2006 ) 此外, Internet工程任务组 IETF也正在制定 VDSL2线路管理模型的标 准是:
VDSL2管理对象的定义 ( Definitions of Managed Objects for Very High Speed Digital Subscriber Line 2 ) 上述两个标准组织所建立的 VDSL2线路配置管理模型的思路基本是一 致的, 即将 VDSL2 的线路配置参数分成多个组, 每一组参数称之为模板 ( profile ), 不同组的模板又合成为模板集 ( template )。 当为 VDSL2线路用 户配置参数时, 只要 相应的模板集关联到该线路上即可。 图 1为根据相关技术的 TR-129标准 VDSL2线路配置管理模型中, 线 路与各配置模板的关系示意图, 如图 1所示, 配置管理模型包括有直接配置 在 VDSL2线路 110的线路配置模板集 120,线路配置模板集 120还包括业务 配置模板 130和功率谱配置模板 140, 其中, 业务配置模板 130还包括信道 配置 150。 图 2为根据相关技术的 IETF标准草案 VDSL2线路配置管理模型中 , 线路与各配置模板的关系示意图, 如图 2所示, 配置管理模型包括有直接配 置在 VDSL2线路 210的线路配置模板集 220 ,线路配置模板集 220还包括线 路配置模板 221 和信道配置模板 250。 因此, 从上述图 1 和图 2可以得出 VDSL2线路配置管理模型基本是一致的。 但是 , TR- 129和 IETF定义的这类模型存在的问题主要是 , 环境敏感因 素的变化将导致产生一系列配置模板集以适应这种环境变化, 最终将导致随 着环境因素的变化, 会产生大量的配置模板集, 使得一方面, 随着配置模板 集的数量增加 ,设备上将消耗大量内存用于存储这些配置模板集; 另一方面, 配置模板集的数量增加将加大管理难度和复杂度。 举例来说, 在实际业务应用场景中, 业务配置模板主要用来定义业务速 率的 ,针对不同应用场景可能会有几十种业务配置模板,假设其数量是 n=20; 而功率谱配置模板的主要作用就是定义跟环境噪声、 线缆长度、 线径等有关 的参数,在一个网络中至少可能有几百个这种配置模板才能适应环境的变化, 假设其数量 m=300; 这样, 配置模板集的数量就可能会有: m x n = 300 x 20 = 6000个; 在相关技术中的 ADSL下, 需要管理的配置模板只有 20至 30个, 但 在 VDSL2 这种应用场景下, 由于环境因素的敏感度增加, 同样的管理方式 将导致配置模板集大量增加以适应各种环境变化, 显然, 这种管理方式管理 VDSL2 的难度大, 同时这些配置模板集在网元上占用 艮多内存, 导致了 VDSL2的应用难度大, 限制了 VDSL2的推广应用。 发明内容 针对大量模板集将加大管理难度并且消耗大量内存用于 VDSL2线路管 理的问题而提出本发明, 为此, 本发明的主要目的在于提供一种基于实际业 务应用场景的 VDSL2配置管理模型, 以解决上述问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种基于实际业务 应用场景的 VDSL2配置管理模型 , 包括 VDSL2线路以及关联到 VDSL2线 路的上行速率模板、 下行速率模板、 功率谱模板、 噪声裕度模板、 交织延时 与脉冲噪声保护模板;
