Description
技术领域technical field
本发明涉及信号处理技术，尤其涉及一种信号处理方法及源端设备。The present invention relates to signal processing technology, and in particular, to a signal processing method and source device.
背景技术Background technique
目前光传送网(OTN，Optical Transport Network)设备基本采用电交叉处理方式，对于线路中传递过来的信号，无论信号对应的业务是本地上下的业务，还是途经本地继续向下一个节点传递的业务，所述OTN设备均将信号输入到本地进行电交叉处理，即先将信号经光-电转换，将所有光信号转换成电信号，再经过交叉连接矩阵后，使本地上下的业务做上下处理，使继续向下一个节点传递的业务经电-光转化，将电信号转换成光信号后继续向下传递，如此，完成OTN设备的信号收发。At present, the optical transport network (OTN, Optical Transport Network) equipment basically adopts the electrical crossover processing method. For the signal transmitted in the line, no matter whether the service corresponding to the signal is the service of the local up and down, or the service that continues to be transmitted to the next node through the local, The OTN equipment all input the signal to the local for electrical crossover processing, that is, the signal is first converted into optical-electrical, and all optical signals are converted into electrical signals, and then after the cross-connect matrix, the local uplink and downlink services are processed. The services that continue to be transmitted to the next node are converted into electrical-optical signals, and the electrical signals are converted into optical signals and then continue to be transmitted downward. In this way, the signal transmission and reception of the OTN equipment is completed.
如图1所示，假设OTN节点1和OTN节点2之间有60路信号，则所述60路信号均会经过所述OTN节点1进行交叉连接矩阵，而其中40路进行本地处理，20路需要再经过电交叉转接到线路继续传递到OTN节点3。这样，对于OTN设备的电交叉处理造成一定浪费，占用了本地的交叉资源，增加了信号处理时延，加大了设备功耗。As shown in Figure 1, assuming that there are 60 signals between OTN node 1 and OTN node 2, the 60 signals will pass through the OTN node 1 for cross-connection matrix, and 40 of them are processed locally, and 20 of them are processed locally. It needs to be further transferred to the OTN node 3 through an electrical crossover to the line. In this way, the electrical cross-connect processing of the OTN equipment causes a certain waste, occupies local cross-connect resources, increases the signal processing delay, and increases the power consumption of the equipment.

步骤303：当所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性匹配时，选取与所述第一波长属性信息对应的第一处理策略；其中，所述第一节点属性能够表征所述源端设备对应的标识信息；Step 303: when the first wavelength attribute information matches the first node attribute in the preset wavelength attribute database, select a first processing strategy corresponding to the first wavelength attribute information; wherein the first The node attribute can represent the identification information corresponding to the source device;
本实施例中，所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性匹配，也就是说，所述第一传输信号为需要在本地进行处理的信号，此时，采用第一处理策略在本地对所述第一传输信号进行处理。In this embodiment, the first wavelength attribute information matches the first node attribute in the preset wavelength attribute database, that is, the first transmission signal is a signal that needs to be processed locally. In this case, The first transmission signal is processed locally using a first processing strategy.
步骤304：根据所述第一处理策略对所述第一传输信号进行数据传输处理，以使所述第一传输信号在本地进行传输。Step 304: Perform data transmission processing on the first transmission signal according to the first processing strategy, so that the first transmission signal is transmitted locally.
在一具体实施例中，步骤304可以为：根据所述第一处理策略将所述第一传输信号进行转换处理，得到第二传输信号；在所述源端设备本地对所述第二传输信号进行传输处理。In a specific embodiment, step 304 may be: converting the first transmission signal according to the first processing strategy to obtain a second transmission signal; locally processing the second transmission signal at the source device Carry out transmission processing.
具体地，在本地将所述第一传输信号转入交叉连接矩阵进行处理，即在本地先进行光-电转换处理，将所有光信号转换成电信号，再经过交叉连接矩阵后，在本地做上下业务处理。Specifically, the first transmission signal is transferred to the cross-connection matrix for processing locally, that is, optical-electrical conversion processing is performed locally, all optical signals are converted into electrical signals, and after the cross-connection matrix, the local Up and down business processing.
步骤305：当所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性不匹配时，选取与所述第一波长属性信息对应的第二处理策略；所述第二处理策略不同于所述第一处理策略；随后执行步骤306至步骤308；Step 305: when the first wavelength attribute information does not match the first node attribute in the preset wavelength attribute database, select a second processing strategy corresponding to the first wavelength attribute information; the second processing The strategy is different from the first processing strategy; then steps 306 to 308 are performed;
本实施例中，当确定出所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性不匹配，也就是说，所述第一传输信号不在本地处理，需要向下一节点继续传递，此时，选取第二处理策略对所述第一传输信号进行处理。In this embodiment, when it is determined that the first wavelength attribute information does not match the first node attribute in the preset wavelength attribute database, that is, the first transmission signal is not processed locally, and needs to be sent to the next The node continues to transmit, and at this time, a second processing strategy is selected to process the first transmission signal.
在一具体实施例中，当所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性不匹配，执行步骤A；若当前所述第一传输信号需要进行再生处理时，执行步骤B；若当前所述第一传输信号不需要进行再生处理，执行步骤306至步骤308。也就是说，当所述第一传输信号既不需要在本地处理，也不需要电再生中继，此时，所述源端设备直接将所述第一传输信号转入到线路接口继续向下传递。In a specific embodiment, when the first wavelength attribute information does not match the first node attribute in the preset wavelength attribute database, step A is performed; if the current first transmission signal needs to be regenerated, Step B is performed; if the current first transmission signal does not need to be regenerated, perform steps 306 to 308 . That is to say, when the first transmission signal does not need to be processed locally, nor does it need an electrical regeneration relay, at this time, the source device directly transfers the first transmission signal to the line interface and continues downward transfer.
这里，光信号在长距离传输后性能会有所下降，为保证传输性能质量，需要经过一定距离后进行电再生中继，所以在实际应用中需要执行步骤A。Here, the performance of the optical signal will be degraded after long-distance transmission. In order to ensure the transmission performance quality, it is necessary to perform electrical regeneration and relay after a certain distance. Therefore, step A needs to be performed in practical applications.
步骤306：根据所述第二处理策略检测所述第一传输信号当前的波长属性信息，得到第二波长属性信息；Step 306: Detect the current wavelength attribute information of the first transmission signal according to the second processing strategy, and obtain second wavelength attribute information;
步骤307：配置当前所述第一传输信号的波长属性，以使所述第一传输信号携带有所述第二波长属性信息；Step 307: Configure the wavelength attribute of the current first transmission signal, so that the first transmission signal carries the second wavelength attribute information;
步骤308：发送配置有所述第二波长属性信息的所述第一传输信号。Step 308: Send the first transmission signal configured with the second wavelength attribute information.
在实际应用中，当所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性不匹配时，还需要判断接收到的当前信号是否需要进行再生处理；也即步骤308之前，所述方法还包括：In practical applications, when the first wavelength attribute information does not match the first node attribute in the preset wavelength attribute database, it is also necessary to judge whether the received current signal needs to be regenerated; that is, before step 308 , the method also includes:
步骤A：判断当前所述第一传输信号是否需要再生处理；Step A: judging whether the current first transmission signal needs regeneration processing;
步骤B：当当前所述第一传输信号需要进行再生处理时，对所述第一传输信号进行再生处理后，发送再生处理后的配置有所述第二波长属性信息的所述第一传输信号；Step B: When the current first transmission signal needs to be regenerated, after regeneration is performed on the first transmission signal, the regenerated first transmission signal configured with the second wavelength attribute information is sent ;
步骤C：当当前所述第一传输信号不需要进行再生处理时，发送配置有所述第二波长属性信息的所述第一传输信号。Step C: When the current first transmission signal does not need to be regenerated, the first transmission signal configured with the second wavelength attribute information is sent.
值得注意的是，步骤A的执行顺序只要在步骤308之前，且在确定出所述第一波长属性信息与所述预设波长属性数据库中的第一节点属性不匹配之后执行即可。It is worth noting that the execution sequence of step A only needs to be performed before step 308 and after it is determined that the first wavelength attribute information does not match the first node attribute in the preset wavelength attribute database.
本发明实施例所述的信号处理方法，通过接收网络侧发送的第一传输信号，解析所述第一传输信号，得到第一波长属性信息，将所述第一波长属性信息与预设波长属性数据库进行匹配，进而根据匹配结果，选取与所述第一波长属性信息对应的处理策略，实现根据所述处理策略确定所述第一传输信号的传输处理方式，以使所述传输处理方式与所述第一波长属性信息相匹配的目的；这样，由于根据波长属性采用不同的处理策略处理接收到的第一传输信号，所以能够有效避免电交叉处理浪费的问题，降低了信号处理时延，降低了设备功耗。The signal processing method according to the embodiment of the present invention receives the first transmission signal sent by the network side, analyzes the first transmission signal, obtains first wavelength attribute information, and compares the first wavelength attribute information with the preset wavelength attribute The database is matched, and then according to the matching result, the processing strategy corresponding to the first wavelength attribute information is selected, and the transmission processing method of the first transmission signal is determined according to the processing strategy, so that the transmission processing method is consistent with the transmission processing method.
