步骤201、根据灵活以太网FlexE协议接收发送端发送的承载客户业务流。
接收端根据FlexE协议通过承载通道接收发送端发送的承载客户业务流;其中,承载客户业务流是由发送端在原始客户业务流中周期性或非周期性的插入客户业务的OAM信息后得到的,该OAM信息是由发送端生成的,该OAM信息包括:第一客户特征信息、插入时戳值、故障状态信息、自动保护信息、发送端标志信息等等它们中的任意一项或它们中的任意组合;该OAM信息中的第一客户特征信息是发送端根据预设算法计算目标客户业务流的特征信息后得到的;该目标客户业务流可以根据实际需求进行获取,在此不加以限制;另外,该预设算法也可以根据实际需求进行设置,例如循环冗余校验(Cyclic Redundancy Check,CRC)算法、异或预算算法等等,在此不加以限制。
步骤202、提取所述承载客户业务流中的所述OAM信息。
接收端根据预设处理规则提取承载客户业务流中的OAM信息。作为一种示例性实施方式,在提取之前,发送端与接收端事先定义好针对OAM信息的预设处理规则,即发送端在原始客户业务流中利用预设处理规则插入OAM信息,得承载客户业务流;发送端将预设处理规则通知给接收端,接收端根据该预设处理规则提取承载客户业务流中的OAM信息,保持发送和接收的OAM信息的一致性;这里需要说明的是,预设处理规则可以根据实际需求进行设置,在此不加以限制。
步骤203、对提取的所述OAM信息进行处理,得到承载通道的检测结果。
接收端对提取出的OAM信息进行处理,得到承载通道的检测结果;例如,该检测结果可以包括但不限如下至少任意一项:质量状况的检测结果、传递延迟时间的检测结果、是否出现中断的检测结果、故障状态的检测结果、自动保护信息的检测结果、接入点标志的检测结果等等。想获取到哪些检测结果可以根据对OAM信息进行提取得到的特征信息来确定得 到。

步骤302、在原始客户业务流中插入所述客户业务的OAM信息,得到承载客户业务流。
发送端在原始客户业务流中按照预设处理规则插入客户业务的OAM信息,得到承载客户业务流;这里,可以在原始客户业务流中周期性的插入客户业务的OAM信息,也可以在原始客户业务流中非周期性的插入客户业务的OAM信息。
同时,发送端将预设处理规则通知给接收端,或者在本步骤之前,发送端将预设处理规则通知给接收端;即发送端和接收端需要保持一致的预设处理规则;这里需要说明的是,预设处理规则可以根据实际需求进行设置,在此不加以限制。
步骤303、根据灵活以太网FlexE协议将所述承载客户业务流发送至接收端。
发送端根据FlexE协议通过承载通道将得到的承载客户业务流发送至接收端,供接收端对承载客户业务流进行后续处理。

为了更加体现出本发明的目的,在上述实施例的基础上,进一步的举例说明。
图4为本发明处理承载通道的OAM信息的方法实施例三的流程图,如图4所示,本发明实施例提供的处理承载通道的OAM信息的方法应用在发送端和接收端上,为交互的过程;该方法可以包括如下步骤:
步骤401、发送端生成客户业务的OAM信息。
发送端生成客户业务的OAM信息,该OAM信息包括:第一客户特征信息、插入时戳值、故障状态信息、自动保护信息和发送端标志信息等等;该第一客户特征信息是发送端根据CRC算法计算目标客户业务流的特征信息后得到的。
步骤402、发送端在原始客户业务流中插入客户业务的OAM信息,得到承载客户业务流。
作为一种示例性实施方式,发送端在原始客户业务流中确定出承载OAM信息的特征图案格式,将步骤401中生成的OAM信息周期性的填充到该特征图案格式中,得到承载客户业务流;这里,在发送端确定出承载OAM信息的特征图案格式时,发送端需要将该承载OAM信息的特征图案格式通知给接收端,即发送端与接收端事先定义好承载OAM信息的特征图案格式,让发送端与接收端两者都要知道;其中,承载OAM信息的特征图案格式可以是各类特征的图案格式,只要能和客户业务流的数据报文流区分出来就可以,例如,采用O码块,自定义的其他特征,这些都在本发明的保护范围内。
进一步的,发送端在原始客户业务流中确定承载OAM信息的特征图案格式,包括:发送端在原始客户业务流中确定出正常以太报文和和非正常以太网报文。
发送端将非正常以太网报文中的所有信息块的排列顺序确定为承载OAM信息的特征图案格式。

发送端在原始客户业务流中确定出正常以太报文和和非正常以太网报文,包括:发送端在原始客户业务流中判断每一个以太网报文中的所有信息块是否由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,其中N为大于或等于3的整数;若以太网报文中的所有信息块不是由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,则发送端确定以太网报文为非正常以太网报文;若以太网报文中的所有信息块是由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,则发送端确定以太网报文为正常以太网报文。
步骤403、发送端根据FlexE协议将承载客户业务流发送至接收端。
发送端根据FlexE协议将承载客户业务流发送至接收端,接收端根据FlexE协议接收发送端发送的承载客户业务流。
作为一种示例性实施方式,发送端根据FlexE协议将承载客户业务流的64比特的信息块编码成66比特的信息块,得到编码后的承载客户业务流;其中,66比特的信息块包括有66比特的数据块和66比特的开销块;连续8个66比特的开销块组成一个开销帧,在一个开销帧中携带有OAM信息;之后,发送端将编码后的承载客户业务流发送至接收端。
接收端首先接收发送端发送的编码后的承载客户业务流;之后,接收端根据FlexE协议将编码后的承载客户业务流的66比特的信息块解码成64比特的信息块,得到承载客户业务流;其中,66比特的信息块包括有66比特的数据块和66比特的开销块;连续8个66比特的开销块组成一个开销帧,在一个开销帧中携带有OAM信息。
步骤404、接收端提取承载客户业务流中的OAM信息。
接收端根据发送端确定的承载OAM信息的特征图案格式,提取承载客户业务流中的OAM信息;其中,该OAM信息包括:第一客户特征信息、插入时戳值、故障状态信息、自动保护信息和发送端标志信息等等;该第一客户特征信息是发送端根据预设算法计算目标客户业务流的特征信息后得到的。
这里,进一步的,接收端在提取OAM信息之前有个判断步骤,在接收到的承载客户业务流中确定出正常以太网报文和非正常以太网报文。
接收端根据发送端确定的承载所述OAM信息的特征图案格式,提取承载客户业务流中的所述OAM信息,包括:接收端根据发送端确定的承载OAM信息的特征图案格式,提取承载客户业务流中的非正常以太网报文中所携带的OAM信息;其中,特征图案格式是由发送端根据非正常以太网报文中的所有信息块的排列顺序确定的。
接收端在承载客户业务流中确定出正常以太网报文和非正常以太网 报文,包括:接收端在承载客户业务流中判断每一个以太网报文中的所有信息块是否由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,其中N为大于或等于3的整数;若以太网报文中的所有信息块不是由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,则接收端确定以太网报文为非正常以太网报文;若以太网报文中的所有信息块是由1个数据包首S块、N个连续的数据包数据D块及1个数据包尾T块依次排列组成的,则接收端确定以太网报文为正常以太网报文。
在步骤404之后,接收端对提取后的OAM信息进行处理,得到承载通道的检测结果。作为一种示例性实施方式,接收端针对承载通道的质量状况的检测并得到检测结果可以执行步骤405a至405f;接收端针对承载通道的传递延迟时间的检测并得到检测结果可以执行步骤406a至406b;接收端针对承载通道是否出现中断的检测并得到检测结果可以执行步骤407a至407b;这三个检测任务可以在步骤404后分别同时执行,也可以按照顺序分别执行,具体的执行方式可以根据实际需求进行设置,在此不加以限定。
步骤405a、接收端判断用于计算第二客户特征信息的目标客户业务流与发送端用于计算第一客户特征信息的目标客户业务流是否相同。
接收端判断用于计算第二客户特征信息的目标客户业务流与发送端用于计算第一客户特征信息的目标客户业务流是否相同,若用于计算第二客户特征信息的目标客户业务流与发送端用于计算所述第一客户特征信息的目标客户业务流不相同,则执行步骤405b;若用于计算第二客户特征信息的目标客户业务流与发送端用于计算第一客户特征信息的目标客户业务流相同,则执行步骤405c。

接收端采用与发送端所使用的相同的CRC算法计算目标客户业务流的特征信息,得到第二客户特征信息。
步骤405d、接收端比较第二客户特征信息与第一客户特征信息是否一致。
接收端比较第二客户特征信息与第一客户特征信息是否一致,若第二客户特征信息与第一客户特征信息一致,则执行步骤405e;若第二客户特征信息与第一客户特征信息不一致,则执行步骤405f。
步骤405e、接收端确定承载通道未出现误码,得到承载通道的质量状况的检测结果。
例如,接收端比较第二客户特征信息与第一客户特征信息是一致时,确定承载通道未出现误码,可以得到承载通道的质量状况的检测结果为优秀。
步骤405f、接收端确定承载通道出现误码,得到承载通道的质量状况的检测结果。

步骤406a、接收端获取OAM信息的提取时刻值。
接收端获取OAM信息的提取时刻值,得到提取该OAM信息时的时刻值。
步骤406b、接收端根据OAM信息的提取时刻值与插入时戳值,得到承载通道的传递延迟时间的检测结果。
接收端根据提取OAM信息的提取时刻值与OAM信息中的插入时戳值之间的差值,得到承载通道的传递延迟时间的检测结果。
步骤407a、接收端获取OAM信息的接收时间间隔。
接收端获取OAM信息的接收时间间隔,例如,每隔30秒接收到一次OAM信息,即接收端获取到OAM信息的接收时间间隔为30秒。
步骤407b、接收端根据OAM信息的接收时间间隔,得到承载通道是否出现中断的检测结果。
接收端根据OAM信息的接收时间间隔,得到承载通道是否出现中断的检测结果;接收端根据接收时间间隔大小与预设间隔大小进行比较,得到承载通道是否出现中断的检测结果;例如,接收端判断接收时间间隔30秒大于预设间隔20秒,因此可以确定出承载通道出现中断,得到承载通道出现了中断的检测结果。
这里需要说明的是,在本发明实施例中,仅以接收端针对OAM信息中的第一客户特征信息和插入时戳值来具体说明得到承载通道的检测结果,对于OAM信息中的其他特征信息内容,如故障状态信息、自动保护信息、发送端标志信息等各类特征信息,接收端都可以通过处理得到相应的承载通道的检测结果。
本发明实施例提供的处理承载通道的OAM信息的方法,通过发送端生成客户业务的OAM信息;发送端在原始客户业务流中插入客户业务的OAM信息,得到承载客户业务流;发送端根据FlexE协议将承载客户业务流发送至接收端,同时接收端根据FlexE协议接收发送端发送的承载客户业务流;接收端提取承载客户业务流中的OAM信息;接收端对OAM信息中不同的特征信息分别进行不同的处理,得到不同的特征信息各自对应的承载通道的检测结果;通过本发明的方案,在FlexE协议下,发送端生成包含有不同特征信息的客户业务的OAM信息并通过客户业务流发送给接收端,接收端通过提取客户业务流中的该OAM信息,并对该OAM信息进行分析得到不同特征信息所各自对应的承载通道的检测结果,实现客户业务的承载通道的OAM功能,增加了针对承载通道的监控手段,能够实时监控承载通道的服务质量。
为了进一步体现出本发明的目的,在上述实施例的基础上,举例来说 明。
目前FlexE协议按照物理层100G速率来定义,在发送端中,100G的客户业务流的数据报文在发送前,将数据包报文按照FlexE协议中的64/66比特编码表进行64/66比特编码,将64比特的数据块扩展成66比特的数据块,增加的2比特位于66比特块前面,作为66比特的数据块的开始标志,然后以66比特的数据块的方式从发送端的发送口发送出去;接收端在接收时,接收口从接收到的客户业务流中辨别出66比特块,然后按照FlexE协议中的64/66编码表从66比特的数据块中恢复出原始的64比特的数据块,重新组装出客户业务流的数据报文来。
图5为本发明处理承载通道的OAM信息的方法实施例的66比特的数据块和66比特的开销块的结构示意图;FlexE协议处于64比特到66比特的转换层,在发送66比特的数据块前,对66比特的数据块进行排序和规划,如图5所示,对于100G业务,每20个66比特的数据块划分为一个数据块组,每组中共20个数据块,代表20个时隙,每个时隙代表5G带宽的业务速度;发送66比特的数据块时,每发送完1023个数据块组(1023*20个数据块),插入一个66比特的FlexE开销块,如图2中黑色块所显示,插入FlexE开销块后,继续发送数据块,发送完第二个1023*20个数据块后,再插入FlexE开销块,以此类推,这样在发送数据块的过程中,会周期性地插入FlexE开销块,相邻两个FlexE开销块的间隔是1023*20个数据块,最终形成66比特的信息块,该66比特的信息块具有66比特的数据块和66比特的FlexE开销块。
图6为本发明处理承载通道的OAM信息的方法实施例的FlexE协议的时隙规划表的示意图;当4路100G的物理层(100G PHY)捆绑成一个400G的逻辑业务带宽时,如图6所示,每个物理层仍按照20个数据块组成一个数据块组,每1023个数据块组插入一个FlexE开销块;在FlexE的shim层(垫层),4路20个数据块拼装成一个由80个数据块组成的数据块组,块组中有80个时隙,客户业务在这80个时隙中进行传递,每个时隙带宽是5G,共400G的业务传递带宽。
FlexE开销块在整个客户业务流中起到定位功能,接收端找到FlexE开销块,就可以知道客户业务流中第一个数据块组的位置,以及后续的数据块组的位置。
图7为本发明处理承载通道的OAM信息的方法实施例的FlexE开销帧的结构示意图;如图7所示,连续8个FlexE开销块则组成一个FlexE开销帧;一个FlexE开销块由2位的块标志和64位的块内容组成,块标志位于前2列,后面64列是块内容,第一个FlexE开销块的块标志是10,后面7个FlexE开销块的块标志是01或SS(SS表示内容不确定);第一个FlexE开销块的内容是:0x4B(8位,十六进制的4B)、C比特(1位,指示调整控制)、OMF比特(1位,表示开销帧复帧指示)、RPF比特(1位,表示远端缺陷指示)、RES比特(1位,保留位)、Flexe group number(20位,表示捆绑组的编号)、0x5(4位,十六进制的5)、000000(28位,都是0);其中的0x4B和0x5是第一个FlexE开销块的标志指示,在接收端接收时,当找到一个FlexE开销块中对应位置是0x4B和0x5,则表示该FlexE开销块是FlexE开销帧中的第一个FlexE开销块,和次后接收到连续的7个FlexE开销块组成一个FlexE开销帧;在FlexE开销帧中,reserved部分是保留内容,尚未定义,如图7灰色块部分所示;在FlexE协议中,定义8个FlexE开销块组成一个FlexE开销帧,其中第一个FlexE开销块中由4B(16进制,标识为0x4B)和05(16进制,标识为0x5)两个字段标识;当在FlexE开销块中检测出对应位置是4B和05内容时,则表示该FlexE开销块是第一个FlexE开销块,和后面的7个FlexE开销块组成一个FlexE开销帧。
对于66比特的数据块来说,该数据块具有两种信息块:数据信息块(前两个比特是01,指示该块是数据信息块)和控制信息块(前两个比特是10,指示该块是控制信息块),两种信息块通过各自块中前两位比特进行区分;控制信息块又可以分成各种不同的控制信息块(如空闲信息块),通过控制信息块中第一个字节来区分,将客户业务流进行64/66比特编码之后,通过增加或删除空闲信息块实现速率调整,然后按照时隙配置情况 将66比特的数据块放在FlexE协议的时隙规划表(calendar)中的对应位置。时隙规划表的结构如图6所示,在FlexE协议中每个成员中划分20个时隙(每个时隙是一个66比特的数据块,每个时隙代表5G业务带宽),如果有4个成员,则时隙规划表中共有80个时隙;通过配置,决定每条客户业务选择那些时隙进行承载,时隙规划表将所有时隙进行分组,每组20个时隙,发送给FlexE协议定义的每个成员,每个成员在这些时隙基础上增加上FlexE开销块(FlexE开销块也是66比特块,每间隔20*1023个时隙块插一个FlexE开销块,如图5所示);在时隙规划表中每个成员就是一个修改后的时隙规划表(sub calendar),在一个物理层(PHY)上承载;在插入FlexE开销块后,每个PHY对承载的客户业务流进行扰码(scramble),经过发送端的收发口(PMA)发送出去。
在接收端,PMA接收到信号,经过解扰码(descramble)恢复出66比特的信息块;在66比特的信息块中,每个PHY寻找FlexE协议定义的FlexE开销块,以FlexE开销块为位置基准点,提取所有时隙,获得sub calendar;所有成员的时隙按照次序排列,重新恢复出calendar结构;根据配置信息,从calendar中相应时隙中取出客户业务流,删除空闲信息块,然后进行66/64比特解码,恢复出原始的客户业务。
按照FlexE协议中的64/66比特编码表在客户业务进行切块和64/66比特编码时,由于数据包长度是不确定的,按照64比特进行切割时,包尾的长度可能少于64比特,因此包尾块的种类有好几种;S块表示该块是一个数据包的第一个块。在S块中,第一个字节内容是0x78,表示该块是S块,后面7个字节内容是数据包信息;T块表示数据包的最后一块,有8种不同情况:1、表示是数据包最后一块,但该块中没有带任何数据包内容,数据包最后一个字节内容在上一个数据块中;2、表示是数据包最后一块,该块中只携带了数据报文中最后一个字节内容;3、表示是数据包最后一块,该块中只携带了数据报文中最后2个字节内容;4、表示是数据包最后一块,该块中只携带了数据报文中最后3个字节内容;5、表示是数据包最后一块,该块中只携带了数据报文中最后4个字节内容; 6、表示是数据包最后一块,该块中只携带了数据报文中最后5个字节内容;7、表示是数据包最后一块,该块中只携带了数据报文中最后6个字节内容;8、表示是数据包最后一块,该块中携带了数据报文中最后7个字节内容;如果一个数据包中全部都是数据,则是数据块D。当没有数据信息时,直接插入Idle块,表示是一个空闲块(I块)。
通过64/66比特编码,一个数据报文被转化为一系列连续的66比特块流,报文的第一个66比特块是S块,最后一个66比特块是T块,在S块和T块之间是D块。两个数据报文可能是直接相邻的,即上一个报文的T块(最后一块)之后,是下一个报文的S块(第一个块);前后两个报文也可能是不相邻的,即上一个报文的T之后,和下一个报文的S块之前,中间间插有一个或多个I块。
发送端在对客户业务进行64/66比特编码时,在前后两个数据包的客户业务流(上述实施例中的原始客户业务流)之间,插入OAM信息(上述实施例中的OAM信息),得到新的客户业务流(上述实施例中的承载客户业务流),之后,发送端将新的客户业务流发送至接收端,接收端根据新的客户业务流进行后续处理,这样OAM信息和客户业务报文信息一起传递,OAM信息和客户业务信息传递路径完全一致,接收端可以实时监控FlexE承载通道的服务质量。
接收端在恢复客户业务时,按照与发送端事先确定好的配置规则确定并提取66比特的信息块中哪些是数据信息块,哪些是OAM信息块,如果是OAM信息块,则提取出来对OAM信息块中的特征信息进行分析,可以监控出承载通道的质量状况;例如,1、接收端如果在一定时间内没有收到OAM信息,则判断承载通道出现中断;2、接收端根据OAM信息在发送时的时间值,以及OAM信息接收的时间值,则可以计算出承载通道的传递时间;3、接收端计算前后两段OAM信息之间的目标客户业务流的特征信息(目标客户业务流的特征信息就是对目标客户业务流按照一套算法进行运算的结果,例如,采用CRC8算法,对目标客户业务流进行CRC8算法运算,得到运算结果;或采用异或预算算法,对目标客户业务 流按位进行异或运算,得到运算结果);之后和OAM信息中携带的特征信息进行比较,可以诊断承载通道中信息是否出现误码,给出通道服务质量状况。
图8为本发明处理承载通道的OAM信息的方法实施例的OAM信息块的结构示意图,如图8所示,需要通过一些特殊标志用来区分哪些是数据信息块,哪些是OAM信息块;
OAM信息块是一组特征图案格式的信息块,正常的以太网数据报文最小长度是64字节,而一个信息块最多只能携带8个字节(64比特),因此一个以太网报文进行64/66比特编码后,有多个信息块按照一定的顺序排列,信息块格式是由一个S块(数据包首块)+N个连续的D块(数据包数据块)+一个T块(数据包尾块),由三种类型的信息块按照次序组成,其中N个连续的D块至少有3个,即N为大于或等于3的整数;如果信息块流不符合这种排列顺序,则不是一个正常的以太网报文,因此将不符合以太网报文信息码的顺序定义为OAM信息的特征图案格式;例如后述的图9a,将S块+T块格式定义为OAM信息的特征图案格式,形成OAM信息流段;当在信息块流中检测到S块+T块的特征图案格式,则判断为该S块和T块是OAM信息块,而不是数据报文的S块和T块。
OAM信息块中携带监控信息,在S块(第一个字节内容是78,表示是S块)中携带有客户编号(Client_no)、复帧序列号、监控信息(PM1至PM3)、CRC信息;客户编号可以制定对特定的客户业务流进行监控,复帧编号用来扩展PM1至PM3字节,通过几个连续的帧中PM1至PM3字节,组成许多监控字节,提供误码监控等功能,CRC信息提供OAM信息块的正确性检测;在T块(第一个字节内容是87,表示是T块)中有自动保护倒换(Automatic Protection Switched,APS)信息、延迟时戳(Delay Timestamp,DT);以上为S块和T块所携带OAM信息的举例说明,具体怎么携带的可以自定义设置,例如可以将OAM信息都放置在S块中,也可以将OAM信息都放置在T块中,还可以将OAM信息部分放置在S块中,部分放置在T块中;具体的可以根据实际需求进行设置,在此不加 以限制。
发送端在客户业务流中插入OAM信息块时,需要将OAM信息块插入到前一段数据报文后,后一段数据报文之前,在两个数据报文之间,也就是客户业务流中的T块和S块之间;有时客户业务流不是满速率的,前后两个报文不连续,两个报文之间插入了空闲信息块(I块),这样OAM信息块就插入在I块之间。
发送端在客户业务流中插入OAM信息块后,并将OAM信息及客户业务流发送给接收端后,接收端需要能正确地识别客户业务流中哪些是数据信息块,哪些是OAM信息块;由于数据报文的长度有一定限度,如以太网报文的最小长度是64字节,进行64/66比特编码后有10个66比特块(1个S块,携带7个字节数据;7个数据块(D块),携带56个字节数据;1个T块,携带1个字节数据);对正常的以太网报文,当S块和T块之间会有多个数据块(D块);当S块和T块之间没有D块,或D块很少,或之间有I块时,这段客户业务流都是非正常的数据流,可以用于定义为承载OAM信息块内容。
因此,在发送端插入OAM信息时,或插入OAM信息之前,需要发送端和接收端事先商量好采用承载OAM信息的特征图案格式;其中,承载OAM信息的特征图案格式有多种,以下举例进行说明。

图9g为本发明处理承载通道的OAM信息的方法实施例的承载OAM信息的特征图案格式的示意图七,如图9g所示,连续相邻的1个S块、1个I块、1个T块,组成S-I-T信息流段,用于承载OAM信息,定义为OAM信息流段;该OAM信息流段前面有个前一个数据流段的T块,后面有个下一个数据流段的S块,OAM信息流段在前后两个数据流段之间。
