[0040] Optionally, in the embodiment, after the first automatic protection switching module obtains the target data, it is necessary to determine the sending mode in which the first automatic protection switching module is located, wherein the target data is data sent by the first chip logic forwarding module through the same service port on the first device, the sending mode can include but is not limited to a working mode, a protection mode, or a mode of being in the working mode and the protection mode at the same time, the working mode or the protection mode does not need to copy the data, and the mode of being in the working mode and the protection mode at the same time needs to copy the data; and whether the target data needs to be copied is determined according to the sending mode in which the first automatic protection switching module is located; wherein the first sending mode can be but is not limited to the mode of being in the working mode and the protection mode at the same time.

[0041] Optionally, in the embodiment, in the case that it is determined that the first automatic protection switching module is in the first sending mode, i.e., the target data needs to be copied, the obtained target data is copied twice to obtain two target data; the two target data are sent to the second FlexE working client and the second FlexE protection client of the second device through the working channel and the protection channel by the first FlexE working client and the first FlexE protection client, respectively.

[0042] Optionally, in the embodiment, the APS based on the FlexE client is not aware of the service, and the FlexE APS technology can be deployed on the premise of not affecting the existing service.

[0043] For example, as shown in FIG. 1, a FlexE network is deployed in a network, and the FlexE network comprises a first device and a second device. Figure 3As shown, the data sent by the chip logic forwarding module 300 reaches the replication module 302 in the APS via the port 301, and the replication module 302 replicates the received data in the case that the APS is in both the working mode and the protection mode, one copy of the data is transmitted to the logical link layer 305, the working client 307, and the partial physical coding sublayer (PCS) 309 in turn via the working link 303, and the other copy of the data is transmitted to the logical link layer 306, the working client 308, and the partial PCS 310 in turn via the protection link 304, and the partial PCS 309 and the partial PCS 310 send the data to the FlexE pad layer 311 and the partial PCS 312 in turn, and send the data out via the physical medium 313.

[0044] Through the scheme provided by the embodiment of the present application, the target data sent by the first chip logic forwarding module on the first device is acquired; in the case that the first automatic protection switching module on the first device is in the first sending mode, the acquired target data is copied twice to obtain two copies of the target data; and the two copies of the target data are sent to the second device through a target protection channel and a target working channel in the flexible Ethernet FlexE respectively, wherein the target protection channel is a protection channel between the first FlexE protection client on the first device and the second FlexE protection client on the second device, the target working channel is a working channel between the first FlexE working client on the first device and the second FlexE working client on the second device, the first FlexE protection client and the first FlexE working client on the first device correspond to the same service port, the target data is data sent by the first chip logic forwarding module through the same service port on the first device, and the second FlexE protection client and the second FlexE working client on the second device correspond to the same service port. By using the above technical scheme, the automatic protection switching of the flexible Ethernet client is realized by adding the data replication function and the replicated data can be sent to the opposite device through the working channel and the protection channel, and the technical problem that the APS technology cannot be applied to the flexible Ethernet client is solved.

[0045] In one example embodiment, sending the two copies of the target data to the second device through the target protection channel and the target working channel in the flexible Ethernet FlexE respectively includes: allocating a first time slot to a first copy of the two copies of the target data, and sending the first copy to the second device through the target protection channel on the first time slot; and allocating a second time slot to a second copy of the two copies of the target data, and sending the second copy to the second device through the target working channel on the second time slot.

[0046] It should be noted that the FlexE pad layer divides each 100GE PHY in the FlexE group into a data bearing channel of 20 slots, and the bandwidth corresponding to each slot is 5Gbps. Therefore, each data in FlexE is transmitted on the time slot allocated to it.

[0047] Through the scheme provided in the embodiments of the present application, different data is allocated different transmission time slots, which facilitates the receiving end to identify different data, and thus avoids conflicts between data.

[0048] In one example embodiment, the target data is transmitted to the second device through the target protection channel or the target working channel when the first automatic protection switching module on the first device is in the second transmission mode.

[0049] Optionally, the second transmission mode can include but is not limited to a working mode and a protection mode; the target data is transmitted to the second device through the working channel when the first automatic protection switching module is in the working mode; and the target data is transmitted to the second device through the protection channel when the first automatic protection switching module is in the protection mode.

[0053] For example, as shown in FIG. 4, the first automatic protection switching module is in a working state, and after the chip logic forwarding module 400 transmits data via the port 401, the data is transmitted to the opposite device via the working link 403 by the copying module 402, without transmitting the data via the protection link 404. Figure 4

[0054] As shown in FIG. 4, the first automatic protection switching module is in a working state, and after the chip logic forwarding module 400 transmits data via the port 401, the data is transmitted to the opposite device via the working link 403 by the copying module 402, without transmitting the data via the protection link 404. Figure 5 ​As shown, the first automatic protection switching module is in a protection state, after receiving the data sent by the chip logic forwarding module 500 via the port 501, the copy module 502 sends the data to the opposite device via the protection link 504, without sending the data via the working link 503.

[0058] Through the scheme provided by the embodiment of the present application, according to the state of the automatic protection switching module, the received data is determined, so that only one way of data enters the chip logic forwarding module.

[0059] In one example embodiment, according to the state of the second automatic protection switching module on the second device, sending one of the two target data to the second chip logic forwarding module on the second device comprises: in the case that the state of the second automatic protection switching module is in a protection state, sending the first target data of the two target data to the second chip logic forwarding module on the second device, wherein the first target data is one of the target data sent by the first device through the target protection channel and received by the second device; and / or in the case that the state of the second automatic protection switching module is in a working state, sending the second target data of the two target data to the second chip logic forwarding module on the second device, wherein the second target data is one of the target data sent by the first device through the target working channel and received by the second device.
