OAM Block Window Detection for Lower MTN Processing Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OAM block detection in Metro Transport Networks (MTN) requires significant hardware resources and complex implementation due to block-by-block detection, which is inefficient.
Innovation Solution
A method and device for detecting OAM blocks by setting a detection window based on the location and period of the OAM block, allowing detection within this window rather than block-by-block, thereby reducing resource requirements and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If block-by-block detection method is used, then detection accuracy is maintained, but hardware resource consumption increases and implementation complexity increases
Solution Approach 1:
The patent divides the continuous block stream into discrete detection windows based on the periodic characteristics of OAM blocks. Instead of processing every block individually, the system segments the stream into relevant detection intervals, reducing the total number of blocks that need to be examined while ensuring OAM blocks are not missed due to their periodic transmission pattern.
Solution Approach 2:
The patent utilizes the periodic transmission characteristic of OAM blocks to establish a detection window mechanism. By identifying the period at which OAM blocks are transmitted, the system creates periodic detection windows that align with these transmissions, allowing efficient detection without examining every single block in the stream.
2Reliability
If block-by-block detection method is used, then no OAM block is missed, but processing time increases
Solution Approach 1:
The patent performs preliminary identification of OAM block positions based on their periodic transmission characteristics before actual detection. By pre-calculating where OAM blocks are likely to appear in the block stream, the system can prepare detection windows in advance, reducing the reactive processing time needed during actual detection while ensuring no blocks are missed.
