Example Embodiment
[0077] Example 1:
[0078] An embodiment of the present application provides a data processing method, device and system. This embodiment is based on figure 2 As an example, assume that ONU1, ONU2, and OTN1 are devices on the service sending side, and OTN2, ONU4, and ONU3 are devices on the service receiving side. It should be noted that this embodiment assumes that there is no bearer network between the ONU device and the OTN device. In the actual application process, any ONU device can be a sending or receiving device, and the corresponding OTN device is a sending or receiving device. Generally, ONU equipment and OTN equipment usually have the functions of sending and receiving service data at the same time.
[0079] Figure 5 The steps that need to be performed for the data processing of the above equipment are given. The specific description is as follows:
[0080] S501: Send multiple passive optical network (PON) upstream data frames;
[0081] Specifically, ONU devices (for ...
Example Embodiment
[0106] Example 2:
[0107] An embodiment of the present application provides another data processing method, device and system. This embodiment is based on figure 2 As an example, assume that ONU1, ONU2, and OTN1 are devices on the service sending side, and OTN2, ONU4, and ONU3 are devices on the service receiving side. It should be noted that, unlike Embodiment 1, this embodiment assumes that there is a bearer network between the ONU1 and the OTN1 device. In other words, the ONU1 device is not directly connected to the OTN1 device, but is interconnected through a bearer network.
[0108] In this embodiment, the steps performed by the ONU device and the OTN device are basically the same as the first embodiment. In addition, optional steps that the OTN device can perform, such as bandwidth allocation, bandwidth adjustment, etc., are the same as those of the OTN device in Embodiment 1. Specifically, see Figure 5 As well as the explanation of the related steps, I won't repeat the...
Example Embodiment
[0119] Example 3:
[0120] An embodiment of the present application provides yet another data processing method, device, and system. This embodiment is based on figure 2 As an example, assume that ONU1, ONU2, and OTN1 are devices on the service sending side, and OTN2, ONU4, and ONU3 are devices on the service receiving side. It should be noted that, unlike Embodiment 1, this embodiment assumes that there is a bearer network between the ONU 2 and the OTN 1 device. In other words, the ONU2 device is not directly connected to the OTN1 device, but is interconnected through a bearer network.
[0121] In this embodiment, the steps performed by the ONU device and the OTN device are basically the same as the first embodiment. In addition, the optional steps that the OTN device can perform, such as bandwidth allocation, bandwidth adjustment, etc., are the same as those of the OTN device in Embodiment 1. Specifically, see Figure 5 And the related step explanation, I won't repeat them he...
