Description

Information transmission method, device, equipment and computer readable storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, device, and computer readable storage medium. Background With the development of communication technology, ethernet standard rates have failed to meet the ethernet interface rates required for ethernet traffic. Based on this, flexible ethernet (flexible ethernet, flexE) technology creates an adaptation layer between a Media Access Control (MAC) layer and a physical coding sublayer (physical coding sublayer, PCS), which enables decoupling of the MAC rate and the PCS rate to accommodate different ethernet interface rates. In the process of transmitting the traffic stream of the ethernet service using FlexE technology, the management channel information of FlexE is also transmitted. Disclosure of Invention The application provides an information transmission method, a device, equipment and a computer readable storage medium, which are used for transmitting management channel information in FlexE, and the technical scheme is as follows: in a first aspect, an information transmission method is provided for transmitting management channel information in FlexE, where the method includes obtaining a first overhead frame, where a first bit of the first overhead frame is used to carry management channel information of a first channel, the first bit includes a bit different from a second bit, where the second bit is a bit in a first code block occupied by a management channel in an overhead frame corresponding to the first channel, and transmitting the first overhead frame through the first channel. The first bit is a bit included in the first overhead frame, and the management channel information is carried by multiplexing the first bit included in the first overhead frame, so that the structure of the first overhead frame is not required to be changed, the compatibility problem is avoided, and the universality is wide. And, because the first bit is the bit included in the first overhead frame, the process of transmitting the management channel information by using the first bit does not occupy extra transmission bandwidth, and the bandwidth utilization rate is high. In one possible implementation, the first code block is at least one of a fourth overhead code block, a fifth overhead code block, a sixth overhead code block, a seventh overhead code block, or an eighth overhead code block in an overhead frame corresponding to the first channel. The first code block may include one or more overhead code blocks in an overhead frame, with high flexibility. And, in the case where the first code block includes a plurality of overhead code blocks, the management channels in the plurality of overhead code blocks occupy more bits than the management channels in the single overhead code block, the management channels in the first code block supporting the transmission of more management channel information. In one possible implementation, where the first channel includes a plurality FlexE of instances, the first code block is at least one of a fourth overhead code block, a fifth overhead code block, a sixth overhead code block, a seventh overhead code block, or an eighth overhead code block in an overhead frame corresponding to a first FlexE of the plurality FlexE of instances. Even if the first channel includes a plurality of FlexE instances, not all of the fourth overhead code block-eighth overhead code block of the overhead frame corresponding to each FlexE instance are the first code block, but the fourth overhead code block-eighth overhead code block in the overhead frame corresponding to the first FlexE instance is used as the first code block, so that the position of the channel in the overhead frame is explicitly managed by defining the first code block. In one possible implementation, the first bit includes a bit corresponding to a reserved field of the first overhead frame. The reserved field belongs to an unused field in the first overhead frame, and the field utilization rate of the first overhead frame is improved by reusing the unused reserved field in the first overhead frame and using the original unused reserved field to carry the bit of the management channel information. In one possible implementation, the reserved field includes at least one of a reserved field in a second overhead code block or a reserved field in a third overhead code block of the first overhead frame. The application is not limited to reserved fields used for carrying management channel information, and can be reserved fields in the second overhead code block, reserved fields in the third overhead code block, reserved fields in the second overhead code block and the third overhead code block, and the flexibility is high. In one possible implementation, the first overhead frame is an overhead f
