Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The invention provides a channel configuration method.

[0048] refer to image 3 , image 3 It is a schematic flowchart of the first embodiment of the channel configuration method of the present invention.

[0049] This embodiment proposes a channel configuration method, and the channel configuration method includes:

[0050] Step S10, the optical line terminal OLT acquires the uplink channel corresponding to each downlink channel;

[0051] In a general PON network, the channel in the optical line terminal is a TWDM channel. Each TWDM channel is divided into an uplink channel and a downlink channel. It usually includes multiple uplink channels and downlink channels. An uplink channel and a downlink channel form a physical channel. The OLT transmits data to the ONU through the downlink channel in the physic...

Abstract

The invention discloses a channel configuration method. The channel configuration method comprises steps that: an optical line terminal OLT acquires uplink channels corresponding to all downlink channels; and the OLT binds the downlink channels and the corresponding uplink channels into a channel beam, wherein the downlinks in the channel beam and any uplink channel in the channel beam are bound into a physical channel. The invention also discloses a channel configuration device. According to the invention, uplink usable bandwidth resources in the channel beam are sharable, and the uplink dynamic bandwidth distribution is free from effects of the downlink channels and can be freely switched between the uplink channels, so a condition that some physical channels are too idle since the physical channels are too busy in the PON network is avoided and bandwidth waste is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel configuration method and device. Background technique [0002] With the development of network technology, the network can be used to transmit a large number of services such as voice, data, and video, so the requirements for bandwidth continue to increase. PON (Passive Optical Network, Passive Optical Network) is produced under this demand. A PON system usually consists of an OLT (Optical Line Terminal, Optical Line Terminal) on the office side, an ONU (Optical Network Unit, Optical Network Unit) on the user side, and an ODN (Optical Distribution Network, Optical Distribution Network). to a multipoint network structure. ODN consists of single-mode optical fiber, optical splitter, optical connector and other passive optical components, and provides optical transmission medium for the physical connection between OLT and ONU. In order to further improve t...
