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...

[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...

Abstract

The invention discloses a data forwarding method, device and system. In one possible implementation, a data forwarding apparatus includes a transceiver and a processor. Wherein the transceiver receives an uplink data frame sent by an optical network unit (ONU) device. And the processor processes the uplink data frame to obtain a data frame group sent to the same target ONU device. Then, the processor encapsulates this set of data frames into an optical transport network (OTN) data frame, utilizing the transceiver to transmit the OTN data frame. According to the data transmission technology disclosed by the invention, by using the ONU equipment with low price and bearing the service with the bandwidth guarantee requirement to the OTN data frame with the corresponding bandwidth, the equipment cost of bearing the service with the bandwidth guarantee requirement by the transmission network is reduced, and meanwhile, the service transmission quality can also be guaranteed.

Description

technical field [0001] This application relates to the field of optical communication, in particular to data transmission technology. Background technique [0002] Optical Transport Network (OTN) has the advantages of large capacity and low latency, and is widely used for data transmission in backbone or aggregation networks. OTN transports a variety of services, such as video services, enterprise private lines, and wireless services. OTN can also be used for the bearer network of other networks. For example, the OTN can be used as a bearer network of a passive optical network (Passive Optical Network, PON) to increase the transmission distance of PON services or provide better service protection. As another example, OTN can be used for 5G (5 th Generation) network transmission of various services. [0003] like figure 1 As shown, for each different service, special equipment must be customized to connect customer data to the OTN bearer network. For example, for video...
