Abstract

The application provides an uplink overhead configuration method, an optical fiber network system and related equipment, which are used for independently configuring uplink overhead aiming at sub-equipment supporting a specific uplink rate, and improving the efficiency of uplink burst. The first message received by the first sub-device includes first indication information, where the first indication information is used to indicate that the first message is applicable to configuring uplink burst overhead parameters of the sub-device supporting the first uplink rate. Under the condition that the first sub-device determines to support the first uplink rate, the first sub-device triggers the uplink burst overhead parameter configured on the basis of the first message, but does not trigger other sub-devices with uplink rates (refer to uplink rates except the first uplink rate) to configure the uplink burst overhead parameter on the basis of the first message, which is beneficial to realizing independent configuration of uplink overhead for the sub-device with a specific uplink rate and further beneficial to improving the efficiency of uplink burst.

Description

Uplink overhead configuration method, optical fiber network system and related equipment The present application is a divisional application, the application number of the original application is 202311319468.2, the original application date is 10 months 10 days 2023, and the whole content of the original application is incorporated by reference into the present application. Technical Field The embodiment of the application relates to the field of optical communication, in particular to an uplink overhead configuration method, an optical fiber network system and related equipment. Background Fiber-to-the-room (fiber to the room, FTTR) refers to a technology that provides fiber medium access to the room downstream of an optical network terminal (optical network terminal, ONT) with fiber instead of a network cable. The fiber optic network system in the FTTR scenario includes a master device and one or more sub-devices, where the master device is capable of triggering an activation procedure of the sub-devices after the sub-devices are online, and configuring an uplink burst overhead parameter for each sub-device (the upstream overhead parameters). In the conventional configuration flow, a main device broadcasts an upstream_overhead message (upflow_overhead message), and each sub-device in the optical fiber network system that receives the Upstream Overhead message configures Upstream Overhead parameters of the sub-devices based on content carried by the Upstream Overhead message. However, there may be sub-devices supporting different uplink rates in the optical network system, and there may be different uplink overhead requirements for the sub-devices supporting different uplink rates. Therefore, the conventional configuration procedure leads to that the sub-devices supporting different uplink rates all adopt the same uplink burst overhead parameter, which may affect the efficiency of uplink burst. Disclosure of Invention The application provides an uplink overhead configuration method, an optical fiber network system and related equipment, which are used for independently configuring uplink overhead aiming at sub-equipment supporting a specific uplink rate, and improving the efficiency of uplink burst. In a first aspect, the present application provides an uplink overhead configuration method, which is applied to an optical fiber network system, where the optical fiber network system includes a main device and a plurality of sub-devices, and the plurality of sub-devices includes a first sub-device. The uplink overhead configuration method provided in the present aspect may be executed by the first sub-device in the optical fiber network system, or may be executed by a part of functional modules or chips in the first sub-device. Taking the first sub-equipment as an example, the first sub-equipment receives a first message, wherein the first message comprises first indication information, the first indication information is used for indicating that the first message is suitable for the sub-equipment supporting the first uplink rate to configure uplink burst overhead parameters, and if the first sub-equipment supports the first uplink rate, the first sub-equipment configures the uplink burst overhead parameters of the first sub-equipment based on the first message. Optionally, if the first sub-device does not support the first uplink rate, the first sub-device does not perform the configuration operation based on the first message. In the application, the first message received by the first sub-device contains first indication information, and the first indication information is used for indicating that the first message is suitable for the sub-device supporting the first uplink rate to configure the uplink burst overhead parameter. The first sub-device triggers configuration of an uplink burst overhead parameter of the first sub-device based on the first message if the first sub-device determines to support the first uplink rate. That is, the first configuration message received by the first sub-device only triggers the sub-device supporting the first uplink rate to configure the uplink burst overhead parameter based on the first message, and does not trigger the sub-devices of other uplink rates (refer to uplink rates other than the first uplink rate) to configure the uplink burst overhead parameter based on the first message, which is beneficial to realizing that the sub-device aiming at the specific uplink rate configures the uplink overhead independently, and further is beneficial to improving the efficiency of the uplink burst. In one possible implementation, the first sub-device supports a second uplink rate, the second uplink rate being different from the first uplink rate. The method further includes the steps that the first sub-device receives a second message, the second message comprises second indication information, the second indication information is used for indicating that the second message i
