实施例四:
本实施例中提供了一种具体的扩展 CC/CV帧中 RDI字段的方法, 在本 实施例中, 具体的扩展方法包括 A或者 B:
A: 将 CC/CV帧中的 RDI字段位扩展为 3位, 在相关技术中, RDI的第 8个比特产生告警指示信号, 在本实施例中, 在 RDI相关第 8比特位的基础 上增加比特位 7和 6, 将 RDI从一个比特位扩展到 3个比特位。 如表 1所示,
比特位 8 比特位 7 比特位 6 对应 RDI
0 0 0 无告警
0 0 1 LOC-RDI
0 1 0 Mismerge-RDI
0 1 1 Unexpected
MEP-RDI
1 0 0 Unexpected
Period-RDI
1 0 1 PHB
mismatch-RDI 1 1 0 保留
1 1 1 保留
表 1
由表 1可以知道, 在原来第 8个比特位的基础上继续扩展比特位 7和比 特位 6, 则可能存在的情况有 23种, 即存在 8种可能的情况。 在相关技术只 存在一个比特位的情况中, 第 8位为 1时, 表示有告警产生; 当第 8位为 0 时, 表示没有告警产生, 在本实施例中, 存在的 8种可能情况中, 当三个比 特位从高位到低位依次为 0、 0、 0时, 表示没有告警产生, 而其他的 7种情 况表示会有相应的告警产生。
在本实施例中, 可选地, 当检测到存在连续性丟失告警时, 在三个比特 位从高位到低位依次为 0、 0、 1 的字段中产生连续性丟失告警的指示信号 LOC-RDI; 当检测到存在错误合并告警时, 在三个比特位从高位到低位依次 为 0、 1、 0中生成错误合并告警的指示信号 Mismerge-RDI; 当检测到存在错 误 MEP告警时,在三个比特位从高位到低位依次为 0、 1、 1中生成错误 MEP 告警的指示信号 Unexpected MEP-RDI; 当检测到存在错误周期告警时, 在三 个比特位从高位到低位依次为 1、 0、 0 中生成错误周期告警的指示信号 Unexpected Period-RDI; 当检测到存在每一跳行为不匹配( PHB mismatch )告 警时, 在三个比特位从高位到低位依次为 1、 0、 1 中生成每一跳行为不匹配 指示信号 PHB mismatch-RDI, 其他的 2种情况处于保留状态。 通过这种扩展 比特位的方法, 会产生的所有可能告警的类型的指示信号。
需要说明的是, 在本实施例中, 可选地选取以上所述的几种情况表示各
1、 0表示产生了 LOC告警指示信号; 1、 1、 1表示产生了 Mismerge告警指 示信号, 也就是说, 在本实施例中, 除了三个比特位从高位到低位依次为 0、 0、 0时, 表示没有告警产生外, 其他 7种情况都有可能产生相应的告警指示 信号, 由哪一种情况产生哪一种告警指示信号, 可根据情况而定, 在此不再 赘述。
釆用本实施例中的 RDI比特位的扩展方法能与支持增强型的设备之间互 通; 当然, 允许的情况下也可以与不支持增强型的设备之间互通, 选择根据 设备的改进情况而定。
B:将 CC/CV帧中的 RDI比特位扩展为 4位,与 A不同的是,本方案中, 在方案 A的基础上, 又继续扩展了比特位 5 , 也就是在 RDI相关第 8比特位 的基础上增加比特位 7、 6和 5 , 将 RDI从一个比特位扩展到 4个比特位。 如 表 2所示,
Figure imgf000010_0001
表 2
由表 2可以知道, 在原来第 8个比特位的基础上继续扩展比特位 7、 比 特位 6和比特位 5 , 则可能存在的情况有 24种, 即存在 16种可能的情况。 在 相关技术只有一个比特位的情况中, 第 8位为 1时, 表示有告警产生; 第 8 位为 0时, 表示没有告警产生, 在本实施例中, 存在的可能 16种情况中, 当 四个比特位中最高位也即第 8个比特位为 0时, 不论其他三个比特位是 0或 者是 1 ,都将表示没有告警产生, 而其他的 8种情况即第 8个比特位为 1时表 示会有相应的告警产生, 釆用本实施例的扩展方案, 可以与不支持增强型的 设备之间进行互通。
在本实施例中, 可选地, 当检测到存在连续性丟失告警时, 在四个比特 位从高位到低位依次为 1、 0、 0、 1 中生成连续性丟失告警的指示信号 LOC-RDI; 当检测到存在错误合并告警时, 在四个比特位从高位到低位依次 为 1、 0、 1、 0中生成错误合并告警的指示信号 Mismerge-RDI; 当检测存在 错误 MEP告警时, 在四个比特位从高位到低位依次为 1、 0、 1、 1中生成错 误 MEP告警的指示信号 Unexpected MEP-RDI; 当检测存在错误周期告警时, 在四个比特位从高位到低位依次为 1、 1、 0、 0中生成错误周期告警的指示信 号 Unexpected Period-RDI; 当检测到存在每一跳行为不匹配的告警时, 在四 个比特位从高位到低位依次为 1、 1、 0、 1中生成每一跳行为不匹配的告警指 示信号 PHB mismatch-RDI; 其他的 3种情况暂时处于保留状态。
与方案 A相同, 本方案中表示产生告警的情况只是一种较佳的情况, 除 了在最高位为 0, 其他位可以为 0或者 1的情况下表示没有告警产生外, 其 他的 8种情况可以任意表示产生的告警种类指示信号, 哪一种情况产生哪一 种告警指示信号根据具体情况设置, 在此不再赘述。
在本实施例中, 所述的在每种比特位从高位到低位中产生或者生成某种 告警类型的指示信号可以理解为用该从高位到低位的特定情况表征某种特定 告警类型的指示信号。
在本实施例中, 可选地, 在每个产生 RDI指示信号的告警源中都设置一 个 RDI产生的控制使能, 所述的控制使能用于控制是否产生 RDI指示信号, 当使能有效时, 根据告警源信息的种类产生相应的 RDI指示信号, 否则不产 生相应的 RDI指示信号。 相应地, 在扩展后的 RDI字段中, 设置一控制使能 位, 所述控制使能位在扩展后的 RDI字段中至少有一位来表示, 其余的位数 可以全部用于表征告警或者告警类型, 或者是剩余的部分位用于表征告警或 者告警类型, 也可用同一个位表征控制使能和表征告警。
釆用本实施例中的网络告警方法, 可以更加详细的将告警源信息的内容 显示出来, 从而有效地根据告警源信息的内容解决存在的可能问题。
