Embodiment 1

[0078] An embodiment of the present application provides a data processing method, device and system. This embodiment takes figure 2 Take the network scenario as an example, assuming 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 can be a sending or receiving device. Generally, the ONU equipment and the 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 executed for the data processing of the above-mentioned equipment are given. The specific description is as follows:

[0080] S501: Send multiple passive optical network (PON) uplink data frames;

Embodiment 2

[0107] An embodiment of the present application provides another data processing method, device and system. This embodiment takes figure 2 Take the network scenario as an example, assuming 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, different from Embodiment 1, this embodiment assumes that there is a bearer network between the ONU1 device and the OTN1 device. That is to say, the ONU1 equipment is not directly connected to the OTN1 equipment, 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 those in Embodiment 1. In addition, the optional steps executable by the OTN device, such as bandwidth allocation and bandwidth adjustment, are the same as those of the OTN device in Embodiment 1. Specifically, see Figure 5 And related step explanations, which wi...

Embodiment 3

[0120]An embodiment of the present application provides yet another data processing method, device and system. This embodiment takes figure 2 Take the network scenario as an example, assuming 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, different from Embodiment 1, this embodiment assumes that there is a bearer network between the ONU2 device and the OTN1 device. That is to say, the ONU2 equipment is not directly connected to the OTN1 equipment, 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 those in Embodiment 1. In addition, the optional steps executable by the OTN device, such as bandwidth allocation and bandwidth adjustment, are the same as those of the OTN device in Embodiment 1. Specifically, see Figure 5 And related step explanations are no...

Abstract

This application discloses a data forwarding method, device and system. In a possible implementation manner, the data forwarding device includes a transceiver and a processor. Wherein, the transceiver receives an uplink data frame sent by an Optical Network Unit (ONU) device. The processor processes the uplink data frame to obtain a data frame group sent to the same destination ONU device. Then, the processor encapsulates the group of data frames into an optical transport network (OTN) data frame, and transmits the OTN data frame by using the transceiver. The data transmission technology disclosed in this application, by using cheap ONU equipment, and carrying the business with bandwidth guarantee requirements to the OTN data frame with corresponding bandwidth, reduces the equipment cost of the transmission network carrying the services with bandwidth guarantee requirements, and at the same time The quality of service transmission can 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...
