BROADCAST PHYOAM information and The logical channel physical layer operation sent in the form of a logical channel maintains and manages the LANE PHYOAM information.
当仅需要发送 BROADCAST PHYOAM信息时,参阅图 3 A所示, 在通信装置物理层内的 Reconciliation层和物理层 PCS 层之间设置 PHYOAM装置 Al , PHYOAM装置 A1包括第一生成模块 300、第一 接收模块 301 , 第一处理模块 302、 第二处理模块 303和第一发送模 块 304。  When only the BROADCAST PHYOAM information needs to be sent, referring to FIG. 3A, a PHYOAM device A1 is disposed between the Reconciliation layer and the physical layer PCS layer in the physical layer of the communication device, and the PHYOAM device A1 includes the first generation module 300 and the first receiving. The module 301, the first processing module 302, the second processing module 303, and the first sending module 304.

第一发送模块 304用于将携带 BROADCAST PHYOAM信息的子 数据流从逻辑通道中发送至接收方;每一个逻辑通道中都设置有对应 的第一发送模块 304。  The first sending module 304 is configured to send the sub-data stream carrying the BROADCAST PHYOAM information from the logical channel to the receiving party; each of the logical channels is provided with a corresponding first sending module 304.
基于上述 PHYOAM装置 A1 , 参阅图 3B所示, 本实施例中, 管 理以太网物理层 0 AM开销的第一种方法的详细流程如下:  Based on the above PHYOAM device A1, as shown in FIG. 3B, in this embodiment, the detailed process of the first method for managing the Ethernet physical layer 0 AM overhead is as follows:
步骤 S300: PHYOAM装置 A1从 Reconciliation层接收待发送的 数据流。  Step S300: The PHYOAM device A1 receives the data stream to be transmitted from the Reconciliation layer.
步骤 S301 : PHYOAM装置 Al 在接收的数据流中添加 IDLE PHYOAM信息。  Step S301: The PHYOAM device Al adds IDLE PHYOAM information to the received data stream.
在实际应用中, 为了降低对数据流携带的数据信息的影响, 有时 需要控制添加的 IDLE PHYOAM信息的数据长度, 例如, 参阅图 3C 所示, PHYOAM装置 Al在接收的数据流中添加占整个数据流数据 长度 8 %的 IDLE PHYOAM信息。 In practical applications, in order to reduce the impact on the data information carried by the data stream, it is sometimes necessary to control the data length of the added IDLE PHYOAM information, for example, see FIG. 3C. As shown, the PHYOAM device A1 adds IDLE PHYOAM information occupying 8% of the entire data stream data length to the received data stream.
步骤 S302 : PHYOAM 装置 A1 判断是否存在需要发送的 BROADCAST PHYOAM信息(即判断是否存在生成的 BROADCAST PHYOAM信息), 若是, 则进行步骤 S303; 否则, 进行步骤 S307。  Step S302: The PHYOAM device A1 determines whether there is BROADCAST PHYOAM information to be transmitted (that is, determines whether the generated BROADCAST PHYOAM information exists), and if yes, proceeds to step S303; otherwise, proceeds to step S307.
步骤 S303: PHYOAM装置 A1按照逻辑通道数目将携带 IDLE PHYOAM信息的数据流分为相应逻辑通道数目的子数据流。  Step S303: The PHYOAM device A1 divides the data stream carrying the IDLE PHYOAM information into the sub-data streams of the corresponding logical channel number according to the number of logical channels.
例如, 参阅图 3D所示, 逻辑通道数目为 10时, PHYOAM装置 A1将携带 8 %的 IDLE PHYOAM信息的数据流分为 10条子数据流, 每条子数据流中均携带 8 %的 IDLE PHYOAM信息, 其中,每条子数 据流的流量可以相同、 也可以不同。  For example, referring to FIG. 3D, when the number of logical channels is 10, the PHYOAM device A1 divides the data stream carrying 8% of IDLE PHYOAM information into 10 sub-data streams, and each sub-data stream carries 8% of IDLE PHYOAM information. The traffic of each sub-data stream may be the same or different.
步骤 S304: PHYOAM装置 A1将每条子数据流中携带的部分或 全部 IDLE PHYOAM信息替换为生成的 BROADCAST PHYOAM信 息。  Step S304: The PHYOAM device A1 replaces part or all of the IDLE PHYOAM information carried in each sub-stream with the generated BROADCAST PHYOAM information.
在实际应用中,若生成的 BROADCAST PHYOAM信息的数据长 度不小于数据流中携带的 IDLE PHYOAM信息的数据长度, 则进行 全部替换;若生成的 BROADCAST PHYOAM信息的数据长度小于子 数据流中携带的 IDLE PHYOAM信息的数据长度, 则进行部分替换。  In actual application, if the data length of the generated BROADCAST PHYOAM information is not less than the data length of the IDLE PHYOAM information carried in the data stream, all replacement is performed; if the generated BROADCAST PHYOAM information has a data length smaller than the IDLE carried in the sub data stream The data length of the PHYOAM information is partially replaced.
步骤 S305: PHYOAM装置 A1将携带 BROADCAST PHYOAM 信息的各子数据流分发至相应的逻辑通道。  Step S305: The PHYOAM device A1 distributes each sub-data stream carrying the BROADCAST PHYOAM information to the corresponding logical channel.
由于子数据流的数目等于逻辑通道数目, 因此, 每条逻辑通道中 都存在一条待发送的携带 BROADCAST PHYOAM信息的子数据流。  Since the number of sub-streams is equal to the number of logical channels, there is a sub-data stream carrying BROADCAST PHYOAM information to be sent in each logical channel.
步骤 S306: PHYOAM装置 A1将携带 BROADCAST PHYOAM 信息的各子数据流从相应的逻辑通道中发送至接收方。  Step S306: The PHYOAM device A1 sends each sub-data stream carrying the BROADCAST PHYOAM information from the corresponding logical channel to the receiver.
步骤 S307: PHYOAM装置 Al将未携带 BROADCAST PHYOAM 信息的各子数据流从相应的逻辑通道中发送至接收方。  Step S307: The PHYOAM device A sends each sub-data stream that does not carry the BROADCAST PHYOAM information from the corresponding logical channel to the receiver.
没有生成的 BROADCAST PHYOAM信息时, PHYOAM装置 Al 将未携带 BROADCAST PHYOAM信息的各子数据流从相应的逻辑 通道中发送至接收方,该未携带 BROADCAST PHYOAM信息数据流 中携带有数据信息和 IDLE PHYOAM信息。 When there is no BROADCAST PHYOAM information generated, the PHYOAM device A1 transmits the sub-data streams that do not carry the BROADCAST PHYOAM information from the corresponding logical channel to the receiver, which does not carry the BROADCAST PHYOAM information stream. It carries data information and IDLE PHYOAM information.
由于逻辑通道与物理通道的数目是——对应的,因此, PHYOAM 装置 A1 先将各子数据流从相应的逻辑通道中发送至对应的物理通 道, 再通过各物理通道将各子数据流发送至接收方, 以下实施例中均 按照此方式传送子数据流, 不再赘述。  Since the number of logical channels and physical channels is corresponding to each other, PHYOAM device A1 first sends each sub-data stream from the corresponding logical channel to the corresponding physical channel, and then sends each sub-data stream to each physical channel through each physical channel. The receiver, in the following embodiments, transmits the sub-data stream in this manner, and details are not described herein.
在上述实施例中,携带 BROADCAST PHYOAM信息的各子数据 流是同时发送的, 由于在每条逻辑通道中都传输了相同的 BROADCAST PHYOAM信息, 因此在部分逻辑通道失效的情况下, PHYOAM 装置 A仍可以从未失效的逻辑通道中将 BROADCAST PHYOAM信息发送至接收方, 这样, 便在一定程度上提高了***资 源的利用率, 同时, 由于未失效的逻辑通道仍可以继续使用, 因此, ***可以继续对以太网物理层 OAM开销进行监控和故障管理,这样, 便在一定程度上提高了***对以太网物理层 OAM开销的监控能力和 故障管理能力。  In the above embodiment, each sub-data stream carrying the BROADCAST PHYOAM information is simultaneously transmitted. Since the same BROADCAST PHYOAM information is transmitted in each logical channel, the PHYOAM device A still fails in the case where part of the logical channels fail. BROADCAST PHYOAM information can be sent to the receiver from the unfailed logical channel, which improves the utilization of system resources to a certain extent. At the same time, since the non-failed logical channel can continue to be used, the system can continue. The OAM overhead of the Ethernet physical layer is monitored and fault managed. This improves the OAM overhead monitoring capability and fault management capability of the Ethernet physical layer to a certain extent.
另一方面,参阅图 3E所示,上述实施例中也可以釆用 PHYOAM 装置 A2来完成相同的流程。 PHYOAM装置 A2第一生成模块 300、 第一接收模块 301 , 第八处理模块 305和第一发送模块 304。  On the other hand, referring to Fig. 3E, the same flow can be accomplished by using the PHYOAM device A2 in the above embodiment.

第一接收模块 301用于接收 Reconciliation层下发的待发送的数 据流。  The first receiving module 301 is configured to receive a data stream to be sent delivered by the Reconciliation layer.
第八处理模块 305 用于根据逻辑通道数目将待发送的数据流分 为相应逻辑通道数目的子数据流, 并在各子数据流中添加 IDLE PHYOAM信息和 /或 BROADCAST PHYOAM信息。  The eighth processing module 305 is configured to divide the data stream to be sent into the sub-data streams of the corresponding logical channel number according to the number of logical channels, and add IDLE PHYOAM information and/or BROADCAST PHYOAM information to each sub-data stream.
若生成的 BROADCAST PHYOAM信息的数据长度已达到设定 阔值, 例如, 达到各子数据流数据长度的 8 % , 则第八处理模块 305 便不再向各子数据流中添加 IDLE PHYOAM信息。  If the data length of the generated BROADCAST PHYOAM information has reached a set threshold, for example, 8 % of the data length of each sub-stream is reached, the eighth processing module 305 no longer adds IDLE PHYOAM information to each sub-stream.
第一发送模块 304 用于将携带 IDLE PHYOAM 信息和 /或 BROADCAST PHYOAM信息的子数据流从逻辑通道中发送至接收 方。 The first sending module 304 is configured to send the sub-data stream carrying the IDLE PHYOAM information and/or the BROADCAST PHYOAM information from the logical channel to the receiving Party.
使用 PHYOAM 装置 A2 来向接收方发送 BROADCAST PHYOAM信息时可以实现相同的技术效果, 在此不再赘述。  The same technical effect can be achieved by using the PHYOAM device A2 to send BROADCAST PHYOAM information to the receiver, and will not be described here.

基于上述 PHYOAM装置 B, 参阅图 4B所示, 本实施例中, 管 理以太网物理层 0 AM开销的第二种方法的详细流程如下:  Based on the foregoing PHYOAM device B, referring to FIG. 4B, in this embodiment, the detailed process of the second method for managing the Ethernet physical layer 0 AM overhead is as follows:
步骤 S400: PHYOAM装置 B从 Reconciliation层接收待发送的 数据流。  Step S400: The PHYOAM device B receives the data stream to be transmitted from the Reconciliation layer.
步骤 S401 : PHYOAM 装置 B 在接收的数据流中添加 IDLE PHYOAM信息。  Step S401: PHYOAM device B adds IDLE PHYOAM information to the received data stream.
同样, 为了避免影响数据流携带的数据信息, 有时需要控制添加 的 IDLE PHYOAM信息的数据长度。 Similarly, in order to avoid affecting the data information carried by the data stream, sometimes you need to control the addition. The data length of the IDLE PHYOAM information.
步骤 S402: PHYOAM装置 B按照逻辑通道数目将携带 IDLE PHYOAM信息的数据流分为相应逻辑通道数目的子数据流; 每条子 数据流中均携带 IDLE PHYOAM信息。  Step S402: The PHYOAM device B divides the data stream carrying the IDLE PHYOAM information into the sub-data streams of the corresponding logical channel number according to the number of logical channels; each sub-data stream carries the IDLE PHYOAM information.
步骤 S403: PHYOAM装置 B将携带 IDLE PHYOAM信息的各 子数据流分发至相应的逻辑通道中。  Step S403: The PHYOAM device B distributes each sub-data stream carrying the IDLE PHYOAM information to the corresponding logical channel.
步骤 S404: PHYOAM装置 B判断各逻辑通道中是否存在需要发 送的 LANE PHYOAM信息 (即判断各逻辑通道中是否存在生成的 LANE PHYOAM信息), 并确认需要发送 LANE PHYOAM信息的逻 辑通道。  Step S404: The PHYOAM device B determines whether there is LANE PHYOAM information to be transmitted in each logical channel (that is, whether or not the generated LANE PHYOAM information exists in each logical channel), and confirms that a logical channel of the LANE PHYOAM information needs to be transmitted.
步骤 S405: PHYOAM装置 B将通过确认的各逻辑通道中的子数 据流所携带的部分或全部 IDLE PHYOAM信息替换为对应的 LANE PHYOAM信息。  Step S405: The PHYOAM device B replaces part or all of the IDLE PHYOAM information carried by the sub-data stream in each logical channel that is confirmed by the corresponding LANE PHYOAM information.
在实际应用中, 若生成的 LANE PHYOAM信息的数据长度不小 于数据流中携带的 IDLE PHYOAM信息的数据长度, 则进行全部替 换; 若生成的 LANE PHYOAM信息的数据长度小于子数据流中携带 的 IDLE PHYOAM信息的数据长度, 则进行部分替换。  In actual application, if the data length of the generated LANE PHYOAM information is not less than the data length of the IDLE PHYOAM information carried in the data stream, all replacement is performed; if the generated LANE PHYOAM information has a data length smaller than the IDLE carried in the sub data stream The data length of the PHYOAM information is partially replaced.
另一方面, 若逻辑通道中不存在需要发送的 LANE PHYOAM信 息, 则 PHYOAM装置 B不对任何子数据流携带的 IDLE PHYOAM 信息进行替换。  On the other hand, if there is no LANE PHYOAM information to be transmitted in the logical channel, PHYOAM device B does not replace the IDLE PHYOAM information carried in any sub-data stream.
步骤 S406: PHYOAM装置 B将携带 LANE PHYOAM信息和未 携带 LANE PHYOAM信息的各子数据流从相应的逻辑通道中发送至 接收方。  Step S406: The PHYOAM device B transmits the sub-data streams carrying the LANE PHYOAM information and the non-LANE PHYOAM information from the corresponding logical channel to the receiver.
在实际应用中, PHYOAM装置 B将各子数据流下发至相应的逻 辑通道后,各子数据流在相应逻辑通道中的发送是相互独立的,例如, PHYOAM装置 B中存在 10条逻辑通道, 其中, 第 7条逻辑通道内 存在需要发送的 LANE PHYOAM信息, 那么, PHYOAM装置 B仅 将下发至第 7 条逻辑通道中的子数据流所携带的部分或全部 IDLE PHYOAM信息替换为相应的 LANE PHYOAM信息, 而并不处理下 发至其它逻辑通道中的子数据流。 这样, 就可以针对每一条物理通道 生成对应的 LANE PHYOAM信息 , 并才艮据响应结果对该物理通道进 行监控和故障管理, 从而将对物理层 OAM开销的管理细化到每一条 物理通道, 提高了对物理层 OAM开销的监控能力和故障管理能力; 另一方面, 由于釆用了多逻辑通道模式, 因此, 在部分物理通道失效 息传送送至接收方,这样,便在一定程度上提高了***资源的利用率。 In practical applications, after the PHYOAM device B delivers each sub-data stream to the corresponding logical channel, the transmission of each sub-data stream in the corresponding logical channel is independent of each other. For example, there are 10 logical channels in the PHYOAM device B, where The LANE PHYOAM information that needs to be sent exists in the 7th logical channel. Then, the PHYOAM device B replaces only part or all of the IDLE PHYOAM information carried by the sub data stream sent to the 7th logical channel with the corresponding LANE PHYOAM. Information, not processed Substreams sent to other logical channels. In this way, corresponding LANE PHYOAM information can be generated for each physical channel, and the physical channel can be monitored and fault managed according to the response result, thereby fine-tuning the management of the physical layer OAM overhead to each physical channel, thereby improving The monitoring capability and fault management capability of the physical layer OAM overhead; on the other hand, due to the use of multiple logical channel modes, the partial physical channel invalidation is transmitted to the receiver, thus improving to some extent. Utilization of system resources.

同样, 若不存在生成的 BROADCAST PHYOAM 信息, 则 PHYOAM装置 C不对任何子数据流携带的 IDLE PHYOAM信息进行 替换。  Similarly, if there is no generated BROADCAST PHYOAM information, PHYOAM device C does not replace the IDLE PHYOAM information carried in any sub-stream.
步骤 S504: PHYOAM装置 C将携带 BROADCAST PHYOAM信 息的各子数据流分发至相应的逻辑通道。  Step S504: The PHYOAM device C distributes each sub-data stream carrying the BROADCAST PHYOAM information to the corresponding logical channel.

那么此时, 若逻辑通道中的子数据流仍携带 IDLE PHYOAM信 息, 并且该子数据流携带的 IDLE PHYOAM信息的数据长度大于对 应的 LANE PHYOAM信息的数据长度 ,则将部分 IDLE PHYOAM信 息替换为 LANE PHYOAM信息; 而若逻辑通道中的子数据流仍携带 IDLE PHYOAM信息 , 并且该子数据流携带的 IDLE PHYOAM信息 的数据长度不大于对应的 LANE PHYOAM信息的数据长度, 则将全 部 IDLE PHYOAM信息替换为 LANE PHYOAM信息 ,并且不再对该 子数据流携带 BROADCAST PHYOAM信息进行替换。  Then, if the sub-data stream in the logical channel still carries the IDLE PHYOAM information, and the data length of the IDLE PHYOAM information carried in the sub-data stream is greater than the data length of the corresponding LANE PHYOAM information, the partial IDLE PHYOAM information is replaced with the LANE. PHYOAM information; if the sub-data stream in the logical channel still carries IDLE PHYOAM information, and the data length of the IDLE PHYOAM information carried in the sub-data stream is not greater than the data length of the corresponding LANE PHYOAM information, then all IDLE PHYOAM information is replaced with LANE PHYOAM information, and the sub-data stream is no longer replaced with BROADCAST PHYOAM information.
第二种情况是: 逻辑通道中存在的 LANE PHYOAM信息需要立 即发送。 那么此时, 若逻辑通道中的子数据流仍携带 IDLE PHYOAM信 息, 则根据相应的 LANE PHYOAM信息对该子数据流携带的 IDLE PHYOAM信息进行替换,并且在 IDLE PHYOAM信息的数据长度小 于相应的 LANE PHYOAM信息的数据长度时, 将该子数据流中携带 的部分或全部 BROADCAST PHYOAM信息替换为 LANE PHYOAM 信息。 The second case is: The LANE PHYOAM information present in the logical channel needs to be sent immediately.
