ODU Path Bandwidth Auto-Setting via Control Signal Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication systems, the transmission capacity of ODU paths between transmission devices is often inadequate or excessive, leading to inhibited rapid signal communication, particularly when the transmission rate is determined through negotiation between source and sink devices.
Innovation Solution
A transmission device and method that monitor control signals during negotiation between user devices to set an appropriate ODU path bandwidth, allowing for automatic setting of the transmission rate and enabling prompt signal communication without requiring carrier intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission capacity of the ODU path is set in advance between transmission devices, then the optical transmission network can be established, but the transmission capacity may be excessive or insufficient when accommodating signals with negotiation-determined transmission rates (such as USB, HDMI, DisplayPort)
Solution Approach 1:
The transmission device automatically determines the transmission rate by monitoring control signals exchanged during negotiation between user devices, and autonomously sets the ODU path transmission capacity without requiring manual configuration by communication carriers. This self-service mechanism resolves the contradiction by making the system adapt to actual signal requirements while reducing operational complexity.
Solution Approach 2:
The transmission device monitors control signals transmitted and received during negotiation between user devices to obtain feedback information about the required transmission rate. Based on this feedback, the device dynamically adjusts the ODU path transmission capacity to match the actual signal requirements, ensuring both reliability and reduced complexity.
2Productivity
If the transmission capacity is insufficient, then communication can be established, but video images cannot be projected on sink devices and rapid signal communication is inhibited
Solution Approach 1:
The transmission device monitors control signals during negotiation to obtain feedback on the required transmission rate, then dynamically sets the ODU path capacity to match actual needs. This ensures the transmission capacity is sufficient for rapid signal communication while maintaining communication reliability by accurately matching capacity to requirements.
Solution Approach 2:
The transmission capacity of the ODU path is made dynamic rather than fixed, allowing the system to adapt transmission capacity in real-time based on the actual signal requirements determined through negotiation monitoring. This dynamic adjustment ensures both rapid communication and high success rate by preventing both insufficiency and excessive capacity.
3Ease of operation
If communication carriers manually change the setting of the ODU path, then the transmission capacity can be adjusted, but labor is required and rapid signal communication is inhibited
Solution Approach 1:
The transmission device automatically determines transmission rate and sets ODU path capacity by monitoring control signals during negotiation, eliminating the need for manual intervention by communication carriers. This self-service approach resolves the contradiction by making setting adjustment extremely easy (automated) while reducing the time required to near-zero levels.
Solution Approach 2:
The manual mechanical process of changing ODU path settings by communication carriers is replaced with an automated electronic monitoring and determination system. The transmission device electronically monitors control signals and automatically configures the path, substituting human operation with an automated control mechanism that is both easier and faster.
