具体实施方式
下面结合附图和实施例说明本申请的技术方案，应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
实施例一
参照图1，图1为本发明实施例一的带宽调整方法的流程示意图。
在本实施例中，该带宽调整方法包括：
步骤S10，检测链路的状态，获得所述链路的状态信息；
其中，本发明实施例主要应用在可以识别链路的状态网络中，比如IPV4网络和MPLS(Multi-Protocol Label Switching，多协议标签交换)网络。用户可以在网络部署中通过网管或OAM(Operation Administration and Maintenance，网络管理)界面设定负载均衡的相关参数，包括：
根据所述链路的状态预置对应的需要调整的所述链路的带宽。比如在判断到所述链路的状态不稳定时，对应设置所述链路的带宽为初始带宽*10％；
在预置时间内，如果所述链路的状态稳定，则设置所述链路的带宽恢复为初始带宽；
可选地，用户还可以通过网管或OAM界面设置每条链路的初始带宽。需要说明的是，设置的每条链路的初始带宽不大于链路的物理带宽，用户可以根据实际情况，设置每个链路的初始带宽。比如，假设有三条链路，三条链路的物理带宽都是1G的，但链路1比链路2稳定，链路2比链路3稳定，根据三条链路的物理带宽和稳定情况，设置分配带宽比例为4:2:1，流量过来的时候，通过链路1的初始带宽为4/7，通过链路2的初始带宽为2/7，通过链路3的初始带宽为1/7。负载分配比例可以预置，也可以支持用户自定义修改。本发明实施例中也可以不设置每条链路的初始带宽，如果不设置每条链路的初始带宽，则默认每条链路的初始带宽为每条链路的物理带宽。
在本发明实施例中，实时检测所述链路的状态，获得所述链路当前的状态，可选地，通过检测所述链路的接口的光强度获得所述链路的状态信息， 还可以通过其他方式获得所述链路当前的状态信息，比如通过感知接口状态，从而获得所述链路的状态信息。
步骤S20，当根据所述链路的状态信息判断到所述链路的状态不稳定时，根据预置规则调整所述链路的带宽。
根据在步骤S10获得的所述链路的状态信息，判断所述链路的状态是否稳定，包括判断所述链路是否发生故障。
可选地，根据在步骤S10检测的所述链路接口的光强度，与预设光强度阈值进行对比，如果所述链路接口的光强度低于预设光强度阈值，则判定所述链路的状态不稳定。也可以通过其他方式判断所述链路的状态，比如将获得的所述链路当前的状态与前一次获得的状态进行对比，如果两个状态不同，则认为所述链路的状态发生改变，即判定所述链路的状态不稳定。如果判断到所述链路的状态稳定，则返回步骤S10重新获得所述链路的状态信息。
如果判断到所述链路的状态不稳定，则根据预置规则调整所述链路的带宽。可选地，如果用户设置了所述链路的初始带宽，则当根据所述链路的状态信息判断所述链路的状态不稳定时，在所述链路的初始带宽的基础上根据预置规则调整所述链路的带宽；如果用户没有设置所述链路的初始带宽，则在所述链路的物理带宽的基础上根据预置规则调整所述链路的带宽。比如直接将所述链路的带宽调整为带宽*10％。还可以调整为其他的带宽，状态不稳定的链路在调整后的带宽小于其在调节之前的带宽。
可选地，如果用户设置了所述链路的初始带宽，则当根据所述链路的状态信息判断所述链路的状态不稳定时，在所述链路的初始带宽的基础上根据预置规则调整所述链路的带宽，并相应调整状态稳定的链路的带宽，使得整个带宽保持不变。比如将状态稳定的链路的带宽调整为初始带宽*110％。也可以不调整状态稳定的链路的带宽。还可以将状态不稳定的链路的带宽直接调整为0，比如当判断到链路发生故障时，在判断到该链路的状态稳定后再调整为初始带宽。
本发明实施例通过检测链路的状态，获得所述链路的状态信息；当根据所述链路的状态信息判断到所述链路的状态不稳定时，根据预置规则调整所述链路的带宽。上述技术方案通过判断所述链路的状态是否稳定，如果所述 链路的状态不稳定，则根据预置规则调整所述链路的带宽，比如减少所述链路的带宽，使得不稳定的链路承担的负载少，并相应增加稳定链路的带宽，从而实现减少网络数据的丢包现象。
实施例二
参照图2，图2为本发明实施例二中的当根据所述链路的状态信息判断到所述链路的状态不稳定时，根据预置规则调整所述链路的带宽的一种流程示意图。
基于本发明实施例一的带宽调整方法，步骤S20可以包括：
步骤S21，根据所述链路的状态确定所述链路当前的风险系数；
其中，用户还可以在网络部署中通过网管或OAM界面，根据所述链路的状态预置对应的风险系数以及与所述风险系数对应的带宽，比如根据所述链路的状态预置对应的风险系数为0-3，其中0为初始值，即每条链路的物理带宽或者用户设置的初始带宽。根据所述风险系数对应设置所述链路的带宽，比如在判断出所述链路的风险系数为1时，对应设置需要调整的所述链路的带宽为初始带宽*80％；在判断出所述链路的风险系数为2时，对应设置需要调整的所述链路的带宽为初始带宽*70％；在判断到所述链路的风险系数为3时，对应设置需要调整的所述链路的带宽为初始带宽*60％。也可以不设置风险系数，比如在判断出所述链路的状态发生改变时，对应设置所述链路的带宽为初始带宽*10％或者为0。
可选地，可以设置在预置时间内，如果所述链路的状态稳定，则设置所述链路的带宽恢复为初始带宽或设置为上一次的带宽。在本实施例中，在预置时间内，如果所述链路的状态稳定，则将所述链路的带宽设置为上一次的带宽。
在本实施例中，可以将所述链路初始带宽的状态对应的风险系数设为0，在所述链路的状态不稳定时，比如判断所述链路的状态发生改变的次数，将所述链路的状态设置为1、2或者3，如果所述链路的状态发生改变的次数越频繁，则设置所述链路当前的风险系数就越高。如果判断出所述链路的状态 稳定，则不设置所述链路的带宽。
步骤S22，将所述链路的带宽调整为与当前的风险系数对应的带宽。
根据步骤S21确定所述链路当前的风险系数，对应调整为与所述链路当前的风险系数对应的带宽，比如在所述链路当前的风险系数为1时，将所述链路的带宽调整为风险系数1对应的带宽，例如，将所述链路的带宽调整为初始带宽*80％。
参照图3，图3为本发明实施例二中根据所述链路的状态确定所述链路当前的风险系数的一种流程示意图。
基于本发明实施例二的带宽调整方法，步骤S21可以包括：
步骤S211，在第一次判断到所述链路的状态不稳定时，确定所述链路当前的风险系数为第一风险系数，并启动计时器；
其中，用户可以在网络部署中通过网管或OAM界面，根据所述链路的状态预置对应的风险系数以及与所述风险系数对应的带宽，可以只设置第一风险系数，所述第二风险系数为所述第一风险系数加上预设风险阈值，所述第一风险系数对应的带宽大于所述第二风险系数对应的带宽。本实施例中，假设预设风险阈值为1。
可选地，在所述链路开始使用过程中，在第一次判断到所述链路的状态不稳定时，确定所述链路当前的风险系数为第一风险系数，并同时启动计时器。
假设第一风险系数为1。在第一次判断到所述链路的状态不稳定之前，所述链路的风险系数则可以设为第零风险系数，也可以不设置风险系数，对应的风险系数为0，此时所述链路的带宽不可设置，即所述链路的带宽为初始值。
在所述链路的状态不稳定时，对应设置所述风险系数的带宽，比如本实施例中设置所述链路的带宽为初始带宽*80％。可选地，在所述链路的状态不稳定或者调整所述链路的带宽时，将所述计时器清零。
可选地，在本发明实施中，还可以一直启动计时器，在第一次判断出所 述链路的状态不稳定时，将计时器清零，并重新计时。
步骤S212，在预置时间内判断所述链路的状态是否稳定；
根据步骤S211启动的计时器，在所述链路的风险系数为第一风险系数时，判断在预置时间内所述链路的状态是否稳定，比如判断所述链路的状态是否再次发生改变，如果发生改变，则认为所述链路不稳定的程度变大；或者通过检测所述链路接口当前的光强度，如果所述链路接口当前的光强度低于预设阈值，也可以认为所述链路不稳定的程度变大。
步骤S213，如果在预置时间内判断到所述链路的状态不稳定，则确定所述链路当前的风险系数为第二风险系数；
根据步骤S212判断结果，如果在预置时间内判断所述链路的状态发生改变或所述链路接口当前的光强度小于或等于预设光强度阈值，即判断到所述链路的状态不稳定。比如在3分钟内判断所述链路的状态发生改变，则确定所述链路当前的风险系数为第二风险系数。假设第二风险系数为2，并对应设置所述链路的带宽为初始带宽*70％。如果所述链路的风险系数为2，在预置时间内判断所述链路的状态再次发生改变，则确定所述链路当前的风险系数为3，可以以此类推，如果所述链路的风险系数为3，在预置时间内判断所述链路的状态再次发生改变，则可以直接调整所述链路的带宽为0。
可选地，所述方法还可以包括：
步骤S214，如果在预置时间内判断所述链路的状态没有发生改变，则确定所述链路当前的风险系数为前一次的风险系数。
根据步骤S212判断结果，如果在预置时间内判断所述链路的状态没有发生改变或所述链路接口当前的光强度大于预设光强度阈值，则说明所述链路状态稳定了，则将所述链路当前的风险系数设为前一次的风险系数。比如在所述链路当前的风险系数为第二风险系数时，在第一个预置时间内判断出所述链路的状态稳定，则将将所述链路当前的风险系数设为第一风险系数；如果在第二个预置时间内判断到所述链路的状态没有发生改变，则将将所述链路当前的风险系数设为初始的风险系数，即风险系数为0，并相应调整所述链路的带宽。
可选地，如果在预置时间内根据所述链路的状态是否发生改变从而判断所述链路是否稳定，则确定所述链路当前的风险系数为前一次的风险系数之前，还可以对所述链路的状态进行判断，判断所述链路当前的状态是否正常，所述链路的状态可以包括down状态和up状态，在所述链路的状态处于up状态时为正常。即可以判断所述链路当前的状态是否为up状态，如果所述链路当前的状态为up状态，则将所述链路当前的风险系数为前一次的风险系数。

  10. 如权利要求9所述的装置，其中，所述确定单元包括：
    第一确定子单元，设置为在第一次判断到所述链路的状态不稳定时，确定所述链路当前的风险系数为第一风险系数，并启动计时器；
    判断子单元，设置为在预置时间内判断所述链路的状态是否稳定；
    第二确定子单元，设置为如果在预置时间内判断到所述链路的状态不稳定，则确定所述链路当前的风险系数为第二风险系数；其中，所述第二风险系数为所述第一风险系数加上预设风险阈值，所述第一风险系数对应的带宽大于所述第二风险系数对应的带宽。
  11. 如权利要求10所述的装置，其中，所述确定单元还包括：
    第三确定子单元，设置为如果在预置时间内判断到所述链路的状态稳定，则确定所述链路当前的风险系数为前一次的风险系数。
  12. 如权利要求10或11所述的装置，所述装置还包括：
    处理模块，设置为在所述调整模块根据预置规则调整所述链路的带宽之后，将所述计时器清零。
  13. 如权利要求8所述的装置，其中，
    所述第一获得模块是设置为通过检测所述链路的接口的光强度检测所述链路的状态，获得所述链路的状态信息；
    所述调整模块是设置为当判断到所述链路的接口的光强度低于预设光强度阈值时，根据预置规则调整所述链路的带宽。
  14. 如权利要求8所述的装置，所述装置还包括：
    第二获得模块，设置为基于用户对所述链路初始带宽的设置命令，获得所述链路的初始带宽，其中，所述链路的初始带宽小于或等于所述链路的物理带宽；
    所述调整模块是设置为当根据所述链路的状态信息判断所述链路的状态不稳定时，在所述链路的初始带宽的基础上根据预置规则调整所述链路的带宽。
