[0028] The first embodiment of the present invention proposes a DPU-based data communication method, image 3 It is a flowchart of a DPU-based data communication method according to an embodiment of the present invention, such as image 3 As shown, the process can include:

[0029] Step 301: Divide the DPU into multiple virtual central office devices vDPUs, and the data transmission channels of each vDPU are isolated from each other.

[0030] Here, the DPU includes multiple virtual optical network units (vONUs) and multiple FTU-Os obtained based on the physical ONU entity; in practical applications, the physical ONU entity can be logically divided into multiple vONUs.

[0031] Here, a corresponding relationship (mapping relationship) can be established between each vONU and the downlink port of each FTU-O, wherein, the downlink port of each FTU-O forms a corresponding relationship with one vONU; in each vONU of the DPU, one The vONU may correspond to one or more downlink por...

[0066] In order to better reflect the purpose of the present invention, further illustrations are made on the basis of the first embodiment of the present invention.

[0067] The second embodiment of the present invention proposes a DPU-based data communication and communication management method, and the specific process may include:

[0068] Step A1: The vONU in the vDPU determines whether to start the registration and online process. After determining to start the registration and online process, it sends a registration request (including the identification SN of the vONU) to the OLT, and the OLT processes the registration request to determine whether to allow the vONU to register and go online.

[0069] Step A2: Each successfully registered vONU has a complete set of PON service configuration parameters (including ONU_ID, OMCI_GEM_Port, multiple GEM_Ports, multiple T-CONT (Allo_ID), etc.) to support the management / service data related to the vDPU on the GPON The data trans...

Abstract

The embodiment of the invention provides a DPU-based data communication and communication management method and a DPU, and the method comprises the steps: dividing the DPU into a plurality of pieces of virtual local side equipment vDPUs, and enabling the data transmission channels of all vDPUs to be isolated from each other; enabling the data transmission channel of each vDPU in the DPU to receiverespective data transmission configuration parameters from an optical line terminal OLT; and enabling the data transmission channel of each vDPU to perform data transmission according to the respective data transmission configuration parameter.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, data communication technologies of access networks, and particularly relate to a data communication and communication management method based on a distribution point unit (DPU) and the DPU, which can be applied to copper cable access systems. Background technique [0002] The copper cable access system includes fast access user terminal (Fast) system and very high-speed digital subscriber line 2 (VDSL2) system, and the Fast system includes G-bit fast access user terminal (G.fast) system and multi-Gbit fast access Enter the user terminal (G.mgfast) system. Their network architecture can be divided into Fast / xDSL (DPU) and Fast / xDSL Terminal Equipment (CPE). figure 1 It is a schematic diagram of the system architecture of Fast / xDSL in related technologies, such as figure 1 As shown, the Fast / xDSL central office equipment (DPU) can provide user-end interfaces to connect to multiple ...
