Embodiment Construction

[0068] 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. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0069] figure 1 An application scenario provided by the embodiment of the present invention is shown. Such as figure 1 As shown, the EPON system may include an EPON OLT and one or more EPON ONUs, and the EPON OLT may be connected to the one or more EPON ONU optical fibers through an optical splitter (Optical Splitter, referred to as "OS"), wherein the EPON The communication between the OLT and the EPON ONU is based on multiple downlink wavelengths and on...

Abstract

Disclosed are a method and an apparatus for device registration and wavelength switching in an Ethernet passive optical network system. The method comprises: sending a windowing message to an ONU; receiving a registration request message that is sent by the ONU according to the windowing message and used for requesting registration, the registration request message carrying wavelength information of the ONU, and the wavelength information comprising a registration downlink wavelength adopted by the ONU for receiving the windowing message; sending the registration message to the ONU according to the registration request message, the registration message comprising a logical link identifier (LLID) allocated by an OLT to the ONU; and receiving a registration acknowledgment message that is sent by the ONU according to the registration message and used for acknowledging completion of the registration. By means of the method and apparatus according to embodiments of the present invention, device registration and wavelength switching can be implemented in an Ethernet passive optical network system that adopts multiple downlink wavelengths and one uplink wavelength for communication, the process can be simplified, and the service volume of the system is increased.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a method and a device for equipment registration and wavelength switching in an Ethernet passive optical network system in the field of optical communication. Background technique [0002] With the rapid development of optical communication technology, a passive optical network (Passive Optical Network, “PON”) system is more and more widely used in optical communication technology. The PON system may include Time Division Multiplexing (Time Division Multiplexing, referred to as "TDM") PON, Gigabit Passive Optical Network (Gigabit Passive Optical Network, referred to as "GPON"), Ethernet Passive Optical Network (Ethernet Passive Optical Network, referred to as "EPON"), Time Wavelength Division Multiplexing (Time Wavelength Division Multiplexing, referred to as "TWDM") PON, Point to Point (Point to Point, referred to as "PtP") wavelength division multiplexing (Wavelength Divisi...
