Virtual Concatenation Group Sequencing via Shared Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for sequencing members in multiple Virtual Concatenation Groups (VCGs) consume excessive hardware logic resources, especially when the number of VCGs is large, due to the independent sequencing circuits required for each group.
Innovation Solution
A method and device that determine a sequencing queue based on the arrival time of the latest member in each VCG, sequencing members in turn, and call the sequencing result after a preset allowed time interval that is the larger of two calculated intervals (T1 and T2), ensuring all members are sequenced before the result is required, thereby reducing resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sequencing circuit is configured for each VCG to sequence members independently according to its LCAS information receiving progress, then the sequencing accuracy and reliability are improved, but the hardware logic resource consumption increases significantly
Solution Approach 1:
The patent merges multiple independent sequencing circuits into a single shared sequencing circuit. The receiving end uses one sequencing circuit that processes LCAS information from multiple VCGs sequentially, rather than having separate sequencing circuits for each VCG. This combining approach maintains sequencing accuracy while significantly reducing hardware logic resource consumption.
Solution Approach 2:
The patent implements periodic action by having the single sequencing circuit process different VCGs in time slots. The circuit sequentially services multiple VCGs according to a scheduled time division pattern, where each VCG receives dedicated sequencing attention at its assigned time slot. This periodic servicing ensures reliable sequencing for each VCG while sharing the hardware resource across multiple groups.
2Productivity
If multiple independent sequencing circuits are used for multiple VCGs, then the sequencing of each VCG can be performed independently and reliably, but the hardware resource consumption increases
Solution Approach 1:
The patent applies dynamics by making the single sequencing circuit dynamically switch between different VCGs based on their respective time slots and LCAS information arrival patterns. The circuit adapts its operation by dynamically selecting which VCG to service next, optimizing the use of hardware resources while maintaining the ability to handle multiple VCGs concurrently through time-division multiplexing.

AI summary
The present invention discloses a method and device for sequencing members of multiple Virtual Concatenation Groups, which relates to virtual concatenation technology in optical communication field. The method comprises determining a sequencing queue of all arrived members of the VCGs according to the order of arrival time of the latest member in each of the VCGs, and sequencing members of each of the VCGs in the sequencing queue in turn; and calling a member sequencing result of each of the VCGs when the time of calling the member sequencing result of each of the VCGs is reached, an interval between the time of calling the member sequencing result of each of the VCGs and the time of starting sequencing of the members of each of the VCGs being greater than or equal to a preset allowed time interval from sequencing to calling the sequencing result. The technical scheme of the present invention can implement effectively sequencing members in multiple VCGs through a sequencing circuit, thereby significantly reducing the logical resource consumption.
