    • Switching process at the occurrence of a path trouble is performed more quickly to reduce the number of packet discards during a traffic transition from a currently used system path to a standby system path within a section to be protected. An OLT (210-W) refers to the DBA information of a PON section and, if receiving no CCM frame at a timing at which the same should be received, then determines that some trouble has occurred on the path (S801) and transmits, to an OAM-compliant NE (200-Z), an application-for-switching frame (1501) to notify the OAM-compliant NE (200-Z) of the abnormal condition. The OAM-compliant NE (200-Z) monitors the occurrence of the trouble within the PON section nearly in real time, starts a switching process (S802) and generates and transmits a standby-system delivery request (321) (S302, S803). An OAM-compliant NE (200-A) switches the communication path to the standby-system passing through an OLT (210-P).
    • 在发生路径故障时的切换过程被执行得更快以减少从当前使用的系统路径到要保护的区段内的备用系统路径的业务转换期间的丢弃丢弃数量。 OLT(210-W)是指PON部分的DBA信息,并且如果在接收相同的定时不接收到CCM帧,则确定在路径上发生了一些故障(S801) 到符合OAM的NE(200-Z),用于切换交换帧(1501)的OAM兼容NE(200-Z)通知异常状态。 符合OAM标准的NE(200-Z)几乎实时监控PON部分内的故障发生,开始切换处理(S802),生成并发送备用系统传送请求(321)(S302,S803) 。 符合OAM标准的网元(200-A)将通信路径切换到通过OLT(210-P)的备用系统。

    • A link aggregation function and maintenance function by MPLS OAM. Identical entry information is stored in plural circuits IF which perform a LA setting. In this way, multiplexing to the same LSP is possible even with different IF. The first network IF is assumed to be OAM ACT, and the second network IF is set to OAM SBY (SBY). OAM frame insertion is performed only by an OAM ACT port. In this way, in an opposite MPLS transmission apparatus, it is possible to prevent CV frame reception above a specified number of frames. Further, a switch forwarding table is set to forward frames from the network side to the first network IF of OAM ACT. The second network IF which was set to OAM SBY does not perform fault detection by CV reception. In this way, incorrect detection of faults due to non-reception of OAM can be prevented.
    • MPLS OAM的链路聚合功能和维护功能。 相同条目信息存储在执行LA设置的多个电路IF中。 以这种方式,即使使用不同的IF,也可以复用到相同的LSP。 第一个网络IF被假定为OAM ACT,第二个网络IF设置为OAM SBY(SBY)。 OAM帧插入仅由OAM ACT端口执行。 以这种方式,在相反的MPLS传输装置中,可以防止CV帧接收高于指定帧数。 此外,设置交换机转发表将帧从网络侧转发到OAM ACT的第一网络IF。 设置为OAM SBY的第二个网络IF不通过CV接收执行故障检测。 以这种方式,可以防止由于不接收OAM导致的故障的错误检测。
