具体实施方式
下面结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
图1为本发明实施例一种光通道传输单元帧的传输方法的流程示意图；如图1所示，所述方法包括：
步骤101，接收第一GFP包。
步骤102，提取所述第一GFP包中的OTUCn，获取所述OTUCn中OTUC的GCC信息，将获取的所述GCC信息重组为第二GFP包。
这里，所述OTUCn是由多个并行的OTUC组成，每个OTUC中都有各自的GCC信息。当接收到所述第一GFP包时，先将所述OTUCn从所述第一GFP包中提取出来，即对所述第一GFP包进行解封；再将所述OTUCn中各个OTUC中的GCC信息提取出来；将提取出来的所有GCC信息重组为第二GFP包。在本发明实施例中，所述将获取的所述GCC信息重组为第二GFP包，具体是以轮询方式在各传输信道中获取所述第一GFP包中的所述GCC信息；然后根据预设的配置信息将获取到的各所述GCC信息重组为所述第二GFP包。具体地，图2为本发明实施例中GCC提取时的轮询示意图；提取GCC信息、将提出的所述GCC信息重组为第二GFP包的方法如图2所示。
如图2所示，假设有十路通信信道，根据CPU的配置信息对十路通信信道中的GCC信息进行轮询提取，其中，所述十路通信信道是指从第0路 至第9路，并且按照从第0路到第9路的顺序进行轮询提取。假定10路通信信道中输入的是两路OTUC5，则从第0路到第4路轮询提取第一路OTUC5中的GCC信息，从第5路到第9路轮询提取第二路OTUC5中的GCC，并将提取到的所有GCC信息重组为所述第二GFP包，形成新的GCC通信信道。由于轮询的速度远快于GCC输入的速度，因此，不必担心GCC输入的数据轮询不到的问题。
步骤103，建立GCC信道，根据建立的所述GCC信道将所述第二GFP包解封为MAC包进行发送。
这里，为所述第二GFP包建立GCC信道。首先只要各个OTUC是对齐的，即各个OTUC的输出帧头脉冲一致、复帧号一致、数据脉冲一致，则认为各个OTUC中的GCC信息是同时被提取出来的，然后再将提取出来的GCC重组为第二GFP包，形成一个完整的GCC通信信道，或者是将提取出来的GCC按照预设的配置信息拼接成不同类型的GCC通信信道。这里，不同类型的GCC通信信道包括：GCC0、GCC1、GCC2、GCC0+GCC1、GCC0+GCC2、GCC1+GCC2、GCC0+GCC1+GCC2，根据预设的配置信息，选择这7种类型中的某一种GCC类型的通信信道来承载所述OTUCn，或者使用形成的完整的GCC通信信道来承载所述OTUCn。然后再根据通道的配置信息，对所述第二GFP包的源地址或目的地址或虚拟局域网标识进行替换，并对FCS进行校验；将FCS检验成功的所述第二GFP解封为MAC包通过接口SGMLL发送出去，而对于FCS校验没通过的第二GFP进行丢弃并统计。
在本发明实施例中，所述通道的配置信息具体可以是指建立的GCC信道类型信息。在传输所述MAC包时，根据通道的配置信息，选择合适的GCC信道类型，将所述MAC包经处理后得到的GFP包分发到相应地通信信道中进行发送。如此，有效地实现了B100G的信息传递。
在本发明实施例中，在所述将获取的所述GCC信息重组为第二GFP包之前，所述方法还包括：
对所述第一GFP包进行解扰，得到解扰后的所述第一GFP包；
提取解扰后的所述第一GFP包中的OTUCn，获取所述OTUCn中OTUC的GCC信息，将获取到的所述GCC信息重组为第二GFP包，并建立GCC信道。
这里，具体是以八比特的位宽对所述第一GFP包进行解扰运算，并提取解扰后的所述第一GFP包中的OTUC的GCC信息，将获取到的所述GCC信息重组为第二GFP包。
在本发明实施例中，在所述根据建立的所述GCC信道将所述第二GFP包解封为MAC包进行发送之前，所述方法还包括：
对所述第二GFP包进行通道号标记；
根据标记的所述通道号对所述第二GFP包进行时分同步；
根据建立的所述GCC信道将将同步成功后的所述第二GFP包解封为MAC包进行发送。
这里，建立的GCC信道中的随机存取存储器(RAM，Random Access Memory)在接收所述第二GFP包时，会根据所述第二GFP包中标记的通道号，在所述GCC信道中查找与该通道号相对应的GCC缓存数据，并读取，将读取出来的缓存数据与刚输入的数据一起进行解扰运算，并将运算结果以八比特位宽保存在RAM中，同时，将所述RAM中原有的数据左移八比特，待下一数据输入时，对左移的数据进行解扰运算。
图3为本发明实施例另一种光通道传输单元帧的传输方法的流程示意图；如图3所示，所述方法包括：
步骤301，接收MAC包，并对接收到的所述MAC包进行FCS校验以及源地址、目的地址或虚拟局域网标识的替换，将FCS校验成功后的MAC 包封装成第三GFP包发送。
这里，对接收到的MAC包进行FCS校验，具体可以按照CPU配置的信息，选择虚拟局域网(WLAN，Virtual Local Area Network)或MAC模式，并在所述WLAN/MAC模式下对所述MAC包进行目的地址(DA，Destination Address)、源地址(SA，Source Addresses)或WLAN ID的替换，将FCS校验成功的MAC包封装成第三GFP包。
在本发明实施例中，还会根据业务的配置信息，比如业务的申请信息和CPU的配置信息，第三GFP包中的GCC信道组合类型信息生成通道号，将所述通道号连同所述第三GFP包一起输出。
步骤302，接收所述第三GFP包中OTUCn发送的GCC插入请求，根据所述GCC插入请求，读取缓存在GCC信道中的第三GFP包。
这里，在所述读取缓存在所述第三GFP包中的GCC包之前，所述方法还包括：根据标记的通道号对接收到的第三GFP包进行时分同步；对同步成功后的所述第三GFP包进行第一加扰，得到加扰后的所述第三GFP包，并在GCC信道中缓存加扰后的所述第三GFP包；根据加扰后的第三GFP包中OTUCn发送的GCC插入请求，读取缓存在所述GCC信道中第一加扰后的第三GFP包。
具体地，读取缓存在所述GCC信道中第一加扰后的第三GFP包包括：根据业务的申请信息和CPU的配置信息，确定所述第三GFP包中OTUCn参与建立所述GCC信道的OTUC；根据参与建立所述GCC信道的OTUC发出的业务调度请求，即GCC插入请求，读取缓存在所述GCC信道中的所述第三GFP包。
在本发明实施例中，根据内部通道的配置信息在GCC信息中读取缓存的第三GCC包的GCC信息，并将读取出的GCC信息与参与所述GCC信道中的OTUC发出的业务调度请求进行匹配，将匹配成功的GCC信息生成 读缓存信号。在本发明实施例中。当所述GCC信道中保存了至少一个第三GCC包时，OTUC会响应一次所述OTUCn下发的GCC插入请求，而OTUCn中的每个OTUC在每响应一次GCC插入请求，就会得到1帧的GCC信息。
本发明中每个OTUC在每响应一次GCC插入请求，就会得到1帧的GCC信息的具体实现与现有技术中OTU4的实现方法不同的是，本发明实施例中建立的GCC信道具有多种信道组合方式，根据不同的组合类型，OTUC可以选择性地参与GCC信道的建立。
步骤303，根据业务的配置信息将读取出的所述第三GFP包，向所述OTUCn中参与建立GCC信道的OTUC发送。
这里，具体建立GCC信道由CPU配置。当OTUCn发出插入GCC请求的业务与OTUC中的通道号业务匹配时，则匹配后的OTUC参与GCC通信信道的建立，并得到GCC信息。然后，根据OTUCn的业务指示、GCC信息的有效指示、GCC信息插入位置指示等信息，将读取出的第三GFP包，插入到各个OTUC的GCC信息位置。
图4为GCC插入时的轮询示意图，如图4所示，以包括5路通信信道为例，假定1路中为OTUC5业务，并发出OTUC5业务的调度请求，当所述调度请求与GCC信道中缓存的GCC包的业务相匹配时，确定1路中的GCC0和GCC1、GCC2全部参与GCC信道的建立，并且在读取缓存在所述GCC信道中的GCC包时，对GCC0、GCC1、GCC2轮询3次，直到所述GCC信道中缓存的数据读空，就不再响应调度请求。
在本发明实施例中，在所述根据业务的配置信息将读取出的所述第三GFP包，向所述OTUCn中参与建立GCC信道的OTUC发送之前，所述方法还包括：
根据标记的通道号对读取出的所述第三GFP包进行时分同步；将同步成功后的所述第三GFP包进行第二加扰，得到第二加扰后的所述第三GFP 包；根据业务的申请信息和CPU的配置信息读取第二加扰后的所述第三GFP包；向所述OTUCn中参与建立所述GCC信道的OTUC发送第二加扰后的所述第三GFP包。
在本发明实施例中，在所述读取缓存在GCC信道中的第三GFP包之前，所述方法还包括：确定所述第三GFP包未全部写入所述GCC信道，且所述GCCP信息的缓存空间已满时，对所述第三GFP包作截包处理，并在截包处设置包围标记；根据所述GCC插入请求，读取缓存在所述GCC信道中的第三GFP包。
具体地，将OTUCn封装成第三GFP包时，会遇到信息未全部写入GCC信道、而所述GCC信道中的RAM缓存空间即将写满的情况，此时，则做截包处理，具体是将未写入包的数据直接丢弃，并为最后写入的数据设置包围标记，然后将打入包围的当前地址跳转到写核心头的地址，并在将新的包长及FCS校验写入核心头的位置后，再跳转回所述当前地址，也就是写包尾标记的下一个地址。
本发明实施例与现有技术相比，以一种较小的资源代价，在兼容OTU4业务基础上，能够以通过新GCC建立各种通信信道类型，并通过新GCC建立的通信信道承载OTUCn的发送。
图5为本发明实施例一种光通道传输单元帧的传输装置的组成示意图，如图5所示，所述装置包括：提取单元501和分发单元502；其中，
所述提取单元501，配置为接收第一GFP包，提取所述第一GFP包中的OTUCn，获取所述OTUCn中OTUC的GCC信息，并将获取到的所述GCC信息重组为第二GFP包；
所述分发单元502，配置为建立GCC信道，根据建立的所述GCC信道将所述提取单元501重组的所述第二GFP包解封为MAC包进行发送。
这里，所述OTUCn是由多个并行的OTUC组成，每个OTUC中都有 各自的GCC信息。当所述提取单元501接收到所述第一GFP包时，将所述OTUCn从所述第一GFP包中提取出来，即对所述第一GFP包进行解封；然后，再将所述OTUCn中各个OTUC中的GCC信息提取出来；并将提取出来的所有GCC信息重组为第二GFP包。在本发明实施例中，所述提取单元501配置为以轮询方式在传输信道中提取所述第一GFP包中的所述GCC信息，根据预设的配置信息将提取到的所述GCC信息重组为所述第二GFP包。详细轮询方式请参照方法实施例中的图2描述。
在本发明实施例中，只要所述提取单元501提取出的各个OTUC是对齐的，即各个OTUC的输出帧头脉冲一致、复帧号一致、数据脉冲一致，则认为各个OTUC中的GCC信息是同时被提取出来的，然后再将提取出来的GCC重组为第二GFP包。并触发分发单元502，由所述分发单元502建立GCC通信信道，来承载所述第二GFP包。所述分发单元502建立GCC通信信道，具体可以按照预设的配置信息，建立不同组合类型的GCC通信信道，这里，不同组合类型的GCC通信信道包括：GCC0、GCC1、GCC2、GCC0+GCC1、GCC0+GCC2、GCC1+GCC2、GCC0+GCC1+GCC2，根据预设的配置信息，选择这7种类型中的某一种GCC类型的通信信道来承载所述OTUCn，或者使用形成的完整的GCC通信信道来承载所述OTUCn。或者使用形成的完整的GCC通信信道来承载所述OTUCn。这里，所述预设的配置信息具体可以是指建立的GCC通信信道组合类型信息。如此，有效地实现了B100G的信息传递。
由于所述分发单元502通过所述第一GFP包，无法实现所述OTUCn的传输，因此，在本发明实施例中，分发单元502配置为根据通道的配置信息，对所述第二GFP包的源地址、目的地址或虚拟局域网标识进行替换，并对FCS进行校验；将FCS检验成功的所述第二GFP解封为MAC包通过接口SGMLL发送出去，而对于FCS校验没通过的第二GFP进行丢弃并统 计。
在本发明实施例中，所述装置还包括解扰单元(图中未示出)，配置为对所述第一GFP包进行解扰，得到解扰后的所述第一GFP包；所述提取单元501配置为获取解扰后的所述第一GFP包中的OTUC的GCC信息，将获取到的所述GCC信息重组为第二GFP包。
这里，所述解扰单元配置为是以八比特的位宽对所述第一GFP包进行解扰运算，并由所述提取单元501提取由所述解扰单元解扰后的所述第一GFP包中的各个OTUC的GCC信息，将获取到的各所述GCC信息重组为第二GFP包。
在本发明实施例中，所述装置还包括标记单元和同步单元(图中均未示出)，其中；
所述标记单元，配置为对所述第二GFP包进行通道号标记；
所述同步单元，配置为根据所述标记单元标记的所述通道号对所述第二GFP包进行时分同步；
所述分发单元，配置为根据建立的所述GCC信道将所述同步单元同步成功后的所述第二GFP包解封为MAC包进行发送。
这里，在所述提取单元501接收所述第二GFP包时，会根据接收到的数据中标记的通道号，在所述GCC信道中查找与该通道号相对应的GCC缓存数据，并将该缓存数据读取出来，与刚输入的数据一起进行解扰运算，并将运算结果以八比特位宽保存在所述提取单元501中，同时，将所述提取单元501中原有的数据左移八比特，待下一帧数据输入时，对其进行读取和解扰运算。
在实际应用中，提取单元501、解扰单元、标记单元和同步单元，均可由装置中的CPU、微处理器(MPU，Micro Processor Unit)、数字信号处理器(DSP，Digital Signal Processor)、或现场可编程门阵列(FPGA，Field  Programmable Gate Array)等实现；分发单元502在实际应用中可通过通信模组(包含：基础通信套件、操作系统、通信模块、标准化接口和协议等)及收发天线实现。
图6为本发明实施例另一种光通道传输单元帧的传输装置的结构示意图；如图6所示，所述方法包括：第一接收单元601，配置为接收MAC包，并对接收到的所述MAC包进行FCS校验以及源地址或目的地址或虚拟局域网标识的替换，将FCS校验成功后的MAC包封装成第三GFP包发送；
第二接收单元602，配置为接收所述第三GFP包中OTUCn发送的GCC插入请求，根据所述GCC插入请求，读取缓存在GCC信道中的第三GFP包；
分发单元603，配置为根据业务的配置信息将读取出的所述第三GFP包，向所述OTUCn中参与建立GCC信道的OTUC发送。
这里，所述第一接收单元601对接收到的MAC包进行FCS校验，具体可以按照CPU配置的信息，选择WLAN或MAC模式，并在所述WLAN/MAC模式下对所述MAC包进行DA、SA或WLAN ID的替换，将FCS校验成功的MAC包封装成第三GFP包。
在本发明实施例中，第一接收单元601还会根据业务的配置信息，比如业务的申请信息和CPU的配置信息，第三GFP包中的GCC信道组合类型信息生成通道号，将所述通道号连同所述第三GFP包一起输出。
所述第二接收单元602在接收到所述第三GFP包中OTUCn发送的GCC插入请求后，根据所述GCC插入请求，所述第二接收单元602读取缓存在所述第三GFP包中的GCC包。
在本发明实施例中，所述装置还包括第一加扰单元(图中未示出)，所述第二接收单元602在读取所述GCC包之前，所述第一加扰单元配置为根据标记的通道号对接收到的第三GFP包进行时分同步，对同步成功后的所 述第三GFP包进行第一加扰，得到加扰后的所述第三GFP包，并在GCC信道中缓存加扰后的所述第三GFP包。所述第二接收单元602配置为根据加扰后的第三GFP包中OTUCn发送的GCC插入请求，读取缓存在所述GFP包中第一加扰后的第三GFP包。
在一实施例中，所述第二接收单元602还配置为根据业务的申请信息和CPU的配置信息，确定所述第三GFP包中OTUCn参与建立所述GCC信道的OTUC；根据参与建立所述GCC信道的OTUC发出的业务调度请求，即GCC插入请求，读取缓存在所述GCC信道中的所述第三GFP包。
在本发明实施例中，根据内部通道的配置信息在GCC信息中读取缓存的第三GCC包的GCC信息，并将读取出的GCC信息与参与所述GCC信道中的OTUC发出的业务调度请求进行匹配，将匹配成功的GCC信息生成读缓存信号。在本发明实施例中。当所述GCC信道中保存了至少一个第三GCC包时，OTUC会响应一次所述OTUCn下发的GCC插入请求，而OTUCn中的每个OTUC在每响应一次GCC插入请求，就会得到1帧的GCC信息。
本发明实施例中每个OTUC在每响应一次GCC插入请求，就会得到1帧的GCC信息的具体实现与现有技术中OTU4的实现不同的是，本发明实施例中建立的GCC信道具有多种信道组合方式，根据不同的组合类型，OTUC可以选择性地参与GCC信道的建立。
建立GCC信道由CPU配置。当OTUCn发出插入GCC请求的业务与OTUC中的通道号业务匹配时，则匹配后的OTUC参与GCC通信信道的建立，并得到GCC信息。由所述分发单元602根据OTUCn的业务指示、GCC信息的有效指示、GCC信息插入位置指示等信息，将读取出的第三GFP包，插入到各个OTUC的GCC信息位置。具体GCC插入时的轮询方法参照方法实施例中图4的描述。
在本发明实施例中，所述装置还包括第二加扰单元(图中未示出)，配 置为根据标记的通道号对读取出的所述第三GFP包进行时分同步；将同步成功后的所述第三GFP包进行第二加扰，得到第二加扰后的所述第三GFP包；所述分发单元603根据业务的申请信息和CPU的配置信息读取第二加扰后的所述第三GFP包；向所述OTUCn中参与建立所述GCC信道的OTUC发送第二加扰后的所述第三GFP包。
这里，所述第一接收单元601将OTUCn封装成第三GFP包，向第二接收单元602发送所述第三GFP包时，会遇到信息未全部写入GCC信道，而GCC信道中的RAM缓存空间即将写满的情况，此时，所述第二接收单元602配置为对所述第三GFP包做截包处理，具体是将未写入包的数据直接丢弃，并为最后写入的数据设置包围标记，然后将打上包围标记的当前地址跳转到写核心头的地址，并在将新的包长及FCS校验写入核心头的位置后，再跳转回所述当前的地址，也就是写包尾标记的下一个地址。
本发明实施例与现有技术相比，以一种较小的资源代价，在兼容OTU4业务基础上，能够通过新GCC信息建立不同类型的通信信道，来承载OTUCn的发送，实现了B100G的有效传递。
在实际应用中，第一加扰单元和第二加扰单元均可由位于装置中的CPU、MPU、DSP、或FPGA等实现；第一接收单元601、第二接收单元602和分发单元603在实际应用中可通过通信模组(包含：基础通信套件、操作系统、通信模块、标准化接口和协议等)及收发天线实现。
