Description

MLPPP组带宽容量的处理方法和装置 技术领域 本发明 涉及通信领域, 尤其涉及一种多 链路点对点协议
( Multilink-Point-to-Point Protocol , 简称为 MLPPP ) 组带宽容量的处理方法 和装置。 背景技术 链路捆绑将多个封装相同链路层协议的接口捆绑到一起, 形成一条逻辑 上的数据链路。 链路捆绑的作用有: ( 1 )流量负载分担: 出 /入流量可以在多 个成员接口之间分担; (2 ) 增加带宽: 链路捆绑接口的带宽是各可用成员接 口带宽的总和; (3 ) 提高连接可靠性: 当某个成员接口出现故障时, 流量会 自动切换到其他可用的成员接口上, 从而提高整个捆绑链路的连接可靠性。
MLPPP就是这样一种链路捆绑技术, 即, 将多条点对点协议 ( Point to Point Protocol, 简称为 PPP )链路绑定到一起, 用于弥补 PPP协议一次只能 处理一个实际链接的局限。 发明人发现在上述的相关技术中, 用户不知道 MLPPP组当前有多少条 协商好的 PPP链路、 以及 MLPPP组能够承载业务流量的最大带宽, 所以, 在 MLPPP组当前所能承载业务流量的带宽低于用户需要的最小带宽时, 用 户也无法得知该情况。 例如, 用户要求的最小带宽为 8M, MLPPP组当前绑 定了 4条 2M的 PPP链路, 一旦某条 PPP链路通讯故障, 则导致该条 PPP 链路不可用, 此时, MLPPP组可用带宽只有 6M (小于最小带宽 8M ), 可见, 此时 MLPPP组所能承载的带宽流量小于用户所要求的最小带宽, 但是, 由 于用户无法得知该带宽不足的情况, 所以, 没有相应的处理机制, 可能会影 响到用户数据的传输性能。 发明内容 本发明的主要目的在于提供一种 MLPPP组带宽容量的处理方案, 以至 少解决上述的相关技术中由于用户不知道 MLPPP组能够 7 载业务流量的最 大带宽而影响用户数据的传输性能的问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种多链路点对点 协议 MLPPP组带宽容量的处理方法。 才艮据本发明的 MLPPP 组带宽容量的处理方法包括以下步 4聚: 统计 MLPPP组绑定的处于开启状态的点对点协议 PPP链路的个数; 判断处于开 启状态的 PPP链路的个数是否小于阈值; 以及在处于开启状态的 PPP链路的 个数小于该阈值的情况下, 提示 MLPPP组当前的带宽容量已不能满足带宽 需求。 进一步地, 上述阈值为预先配置的与带宽需求对应的最小激活链路的个 数。 进一步地,统计 MLPPP组绑定的处于开启状态的 PPP链路的个数包括: 检测 MLPPP组绑定的所有 PPP链路的状态;统计 MLPPP组绑定的所有 PPP 链路中状态为开启的 PPP链路的个数。 进一步地, MLPPP组的状态包括开启和关闭, 当 MLPPP组处于开启状 态时, MLPPP组能够 载业务 4艮文; 当 MLPPP组处于关闭状态时, MLPPP 组停止工作, 不能够承载业务报文。 进一步地, 提示 MLPPP组当前的带宽容量已不能满足带宽需求包括: 置 MLPPP组的状态为关闭, 并上 4艮对应的告警信息。 进一步地, 置 MLPPP组的状态为关闭, 并上 4艮对应的告警信息之后, 该方法还包括: 在处于开启状态的 PPP链路的个数大于或者等于上述阈值的 情况下, 置 MLPPP组的^ I 态为开启。 为了实现上述目的, 才艮据本发明的另一方面, 还提供了一种多链路点对 点协议 MLPPP组带宽容量的处理装置。 才艮据本发明的 MLPPP组带宽容量的处理装置, 该装置包括: 统计模块, 用于统计 MLPPP组绑定的处于开启状态的点对点协议 PPP链路的个数;

否则说明此 PPP链路 down不会影响 MLPPP组的状态变化, 进入步骤 S406。 步骤 S406, 保持现有状态不作任何处理。 步骤 S408, 判断当前 MLPPP组是否处于 up状态。 若不是, 则不需要 再变化 MLPPP组状态, 保持现有状态不作任何处理; 若是进入步骤 S410。 步骤 S410 ,将 MLPPP组的状态置为 down ,使其停止工作,并上报告警。 可见, 本发明实施例是将当前处于 up状态的 PPP链路数与配置的最小 激活链路数 (即, 阈值) 比较, 并根据比较结果进行相应处理。 当 MLPPP 组的带宽容量满足带宽要求时, 走正常流程; 当 MLPPP组的带宽容量不满 足带宽要求时, 釆取保护操作, 将 MLPP组 down掉, 并上 4艮告警。 另外, 当 MLPPP组的带宽容量重新满足带宽要求后, 需要恢复保护操作前的正常 流程。 图 5是根据本发明实施例的 MLPPP组带宽容量的处理装置的结构框图, 如图 5所示, 该装置包括: 统计模块 52 , 用于统计 MLPPP组绑定的处于开 启状态的 PPP链路的个数; 判断模块 54, 耦合至统计模块 52, 用于判断处 于开启状态的 PPP链路的个数是否 'j、于阈值; 以及提示模块 56 , 耦合至判断 模块 54, 用于在处于开启状态的 PPP链路的个数小于该阈值的情况下, 提示 MLPPP组当前的带宽容量已不能满足带宽需求。 通过本发明实施例, 釆用设置阈值的方式, 解决了相关技术中由于用户 不知道 MLPPP组能够承载业务流量的最大带宽而影响用户数据的传输性能 的问题, 避免了 MLPPP组在 PPP链路故障时由于带宽不足而造成的链路拥 塞, 保障了用户对 MLPPP组的带宽要求, 增加了系统的处理能力。 图 6是 居本发明优选实施例的 MLPPP组带宽容量的处理装置的结构 框图, 如图 6所示, 统计模块 52包括: 检测模块 522, 用于检测 MLPPP组 绑定的所有 PPP链路的状态。 优选地, 提示模块 56 包括: 设置模块 562 , 耦合至判断模块 54, 用于 在处于开启状态的 PPP链路的个数小于阈值的情况下, 设置 MLPPP组的状 态为关闭, 其中, 处于关闭状态的 MLPPP组停止工作, 不能够承载业务报 文; 上报模块 564 , 用于上报与 MLPPP组的关闭状态对应的告警信息。 优选地, 设置模块 562还用于在处于开启状态的 PPP链路的个数大于或 者等于上述阈值的情况下, 设置 MLPPP组的状态为开启, 其中, 处于开启 态的 MLPPP组能够 载业务 ^艮文。 上述实施例提供了一种 MLPPP 组保证用户期望带宽的方法, 以及在 MLPPP 组无法保证带宽要求的情况下的相应通告处理。 通过检测绑定的各 PPP链路状态, 判断状态 up (状态 up符合 RFC1661)的 PPP链路数是不是达 到了用户配置的阀值, 若达到了该阈值, 则按照 MLPPP协议正常往下处理, 否则要进行相应的通告和处理机制。 本发明还提供了另一优选实施例的 MLPPP组带宽容量的处理装置, 该 装置可以包括: PPP模块、 MLPPP模块、 MLPPP最小激活链路数配置模块、 激活链路数比较模块和通告处理模块。 其中, 基于 RFC1661 的 PPP模块和 基于 RFC1990的 MLPPP模块用于实现 PPP链路的协商维护以及 MLPPP基 本功能。 在具体实施过程中, 可以包括以下步骤: 首先, 使能 PPP模块和 MLPPP 模块, 即, 与正常流程一样配置 MLPPP组; 然后, 居用户的最小带宽需 求在 MLPPP最小激活链路数配置模块中配置 MLPPP组最小激活链路数;再 者, PPP模块将 PPP链路状态 (up或 down)变化实时告知激活链路数比较模 块, 激活链路数比较模块根据 PPP模块中的 PPP链路状态将当前处于 up状 态的链路数与配置的最小激活链路数进行比较, 并根据比较结果进行相应通 告和处理。具体地,如果当前处于 up状态的链路数小于最小激活链路数(即, MLPPP组的可用带宽不满足用户的要求;), 则将 MLPPP组停止工作 (即, 将 MLPPP组的状态置为 down ), 同时给出告警信息通告用户; 如果当前处 于 up状态的链路数大于最小激活链路数 (即, MLPPP组的可用带宽满足用 户的带宽要求), 则将处于 down状态的 MLPPP组置为 up , 后续按正常流程 处理。 综上所述, 本发明实施例给用户提供了一个配置最小激活链路数的人机 接口, 使得用户可以将期望的最小保证带宽值告知 MLPPP组, 防止了由于 PPP链路故障导致 MLPPP组的带宽容量不满足带宽要求而造成 PPP链路拥 塞, 增加了系统的处理能力, 提高了用户体验。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件 结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
