OAM Frame Segmentation for Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current OAM information transmission schemes face issues such as complicated processing, time-consuming frame alignment, and poor extendibility due to the limitations of length-variable and length-constant OAM frames.
Innovation Solution
The proposed solution involves an information transmission method where OAM information is encapsulated into an OAM frame consisting of N data frames, each with a constant frame length L. The value of N varies with the volume of OAM information, allowing for flexible and efficient transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OAM length-variable frame is used, then the frame format is flexible and can adapt to different message content volumes, but the frame alignment process becomes complicated and time-consuming
Solution Approach 1:
The patent segments the OAM frame into multiple fixed-length data frames (N frames of length L each). This segmentation allows the total frame length to be variable (adapting to different OAM information volumes) while each individual data frame maintains a fixed length structure, simplifying the alignment process at the receiver end.
2Loss of time
If OAM length-constant frame is used, then the frame alignment time is short, but the extendibility is poor and cannot carry large volume message contents
Solution Approach 1:
The patent introduces dynamic scalability by allowing N (the number of data frames) to vary based on the OAM information volume, while keeping each frame's length L constant. This dynamic adjustment of frame quantity rather than individual frame length maintains fast alignment processing while providing extendibility for larger message contents.
3Adaptability or versatility
If OAM length-variable frame is used, then the frame can carry variable message content volumes, but the processing becomes complicated and time-consuming
Solution Approach 1:
By segmenting the OAM frame into N fixed-length data frames, the patent enables variable total frame length to accommodate different message volumes while maintaining simple fixed-length processing for each segment. This segmentation approach preserves processing efficiency by avoiding complex variable-length frame handling.

AI summary
The present disclosure provides an information transmission method, an information transmission device, a communication device and a readable storage medium. The information transmission method includes: obtaining OAM information from an optical network; encapsulating the obtained OAM information to form an OAM frame, the OAM frame including N data frames each having a frame length of L, N varying along with a volume of the OAM information, L being a constant value regardless of the volume of the OAM information; and transmitting the OAM frame. The OAM information is transmitted in a length-constant frame, so it is able to facilitate encoding and decoding of a message, simplifying the processing and reduce the time consumption, and facilitate the extension in accordance with a message content and ensure the extendibility, thereby to solve such problems as complicated processing, being time-consuming, and poor extendibility in the conventional OAM information transmission scheme.
