Problems solved by technology

[0006] In the existing GPON system, one ONU can provide services for one user terminal, and can also provide services for multiple user terminals at the same time; when an ONU provides services for multiple user terminals, multiple user terminals share a total bandwidth, and the user There is a competitive relationship in bandwidth sharing among ONUs, and the user experience is poor; it is also not conducive to the management and maintenance of ONU products

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0043] figure 1 It is a schematic diagram of the implementation flow of the virtual ONU registration method in the embodiment of the present invention. Such as figure 1 As shown, the registration method of the virtual ONU may include the following steps:

[0044] Step 101, N virtual ONUs in the serial number state receive the SN request sent by the optical line terminal OLT; wherein, N is a natural number greater than or equal to 2.

[0045] In a specific embodiment of the present invention, when the ONU is just powered on, it is in the initial state; the ONU listens to the downlink frame sent by the OLT and acquires frame synchronization, and enters the standby state.

[0046] Specifically, the OLT sends a downlink frame every 125 microseconds, and when the ONU is first po...

Abstract

The embodiment of the invention discloses a registration method and system for a virtual optical network unit. The registration method comprises the steps that N virtual ONUs (Optical Network Units) at a serial number state receive a serial number (SN) request sent by an optical line terminal (OLT), wherein N is a natural number which is greater than or equal to 2; each virtual ONU sends an SN response to the OLT; and the OLT registers each virtual ONU according to each SN response.

Description

technical field [0001] The invention relates to chip data communication technology, in particular to a method and system for registering a virtual optical network unit. Background technique [0002] With the development of network technology, the transmission of services such as voice, data, and video has higher requirements on network bandwidth. Gigabit Passive Optical Network (GPON) was born under this demand. . A GPON system usually consists of an Optical Line Terminal (OLT) on the network side, an Optical Network Unit (ONU) and an Optical Distribution Network (ODN) on the user side. Generally, a point-to-multipoint network structure is adopted. Among them, ODN is composed of passive optical devices such as single-mode optical fiber, optical splitter and optical connector, which provide an optical transmission medium for the physical connection between OLT and ONU. [0003] In the GPON system, the broadcast mode is adopted in the downlink direction (that is, the directi...
