Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information synchronization methods for single-stage switching networks fail to address topology changes due to link modifications, leading to reduced switching capability and bandwidth waste.
Innovation Solution
A switching network synchronization method that involves determining a unique target ID by combining suspected target IDs from multiple switching devices, allowing for information synchronization across the network, even with changed topologies, by selecting appropriate access devices as information synchronization devices and controlling synchronization paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connection method is used in single-stage switching networks, then the network structure is simple and easy to implement, but the network cannot adapt to topology changes caused by link modifications, leading to reduced switching capability and bandwidth waste
Solution Approach 1:
The patent implements dynamic synchronization by allowing switching devices to continuously update their suspected target IDs based on current network topology. When link changes occur, devices recalculate and propagate updated IDs through the network, enabling the synchronization mechanism to adapt dynamically to topology changes rather than relying on fixed connections.
Solution Approach 2:
The patent employs feedback mechanisms where switching devices send suspected target ID information to connected access devices, which then propagate this information to other switching devices. This feedback loop allows the network to automatically detect and respond to topology changes, with each device adjusting its synchronization target based on received information from neighbors.
2Reliability
If existing synchronization methods are used, then the implementation is simple for fixed networks, but information synchronization fails when network topology changes, causing bandwidth waste and reduced switching capability
Solution Approach 1:
The patent performs preliminary actions by having switching devices proactively determine and propagate their suspected target IDs before actual topology changes affect synchronization. Access devices collect ID information from multiple switching devices in advance, and the network maintains updated synchronization targets ready for immediate use when link changes occur, preventing synchronization failures rather than reacting to them.
Solution Approach 2:
The patent changes the synchronization parameter from static device IDs to dynamic suspected target IDs that are continuously updated based on current network topology. When topology changes occur, the suspected target ID parameters are recalculated and propagated throughout the network, allowing synchronization to maintain reliability despite structural changes.
3Adaptability or versatility
If multiple access devices are involved in synchronization, then the network can handle topology changes better, but the coordination complexity and communication overhead increase
Solution Approach 1:
The patent segments the synchronization task by assigning different roles to different access devices. Each access device independently collects suspected target ID information from connected switching devices and propagates this information to the network. This segmentation allows multiple access devices to work in parallel without requiring complex centralized coordination, reducing overall system complexity while maintaining adaptability.
