Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bandwidth adjustment is performed via EMS configuration in existing 4G transmission technology, then bandwidth can be adjusted, but link interruption and data flow loss occur
Solution Approach 1:
The patent segments the bandwidth adjustment process into independent slot allocation units. Each slot can be independently configured and activated without affecting the overall link, allowing bandwidth adjustment through selective slot activation rather than complete link reconfiguration. This segmentation enables dynamic bandwidth changes while maintaining continuous data flow through the already-established link.
Solution Approach 2:
The patent implements preliminary slot configuration where slot resources are pre-defined and prepared before actual bandwidth adjustment is needed. The slot templates and resource allocations are established in advance, so when bandwidth adjustment is required, the system can immediately activate pre-configured slots without interrupting the existing link or requiring manual EMS intervention.
2Device complexity
If static bandwidth configuration is used in existing systems, then system complexity is reduced, but transmission efficiency decreases due to inability to adapt to traffic changes
Solution Approach 1:
The patent introduces dynamic slot activation mechanisms that allow the system to adapt bandwidth allocation in real-time based on traffic demands. The system maintains a pool of pre-configured slots that can be dynamically activated or deactivated through automated control, enabling the bandwidth to flexibly respond to traffic changes while keeping the underlying configuration structure relatively simple and manageable.
Solution Approach 2:
The patent changes the bandwidth allocation parameter from a fixed static value to a dynamically adjustable parameter based on slot activation states. By modifying the active slot count and configuration parameters automatically, the system can adapt transmission efficiency to traffic conditions without requiring complex manual reconfiguration, thus improving productivity while maintaining operational simplicity.
3Manufacturing precision
If manual slot configuration is required for bandwidth adjustment, then configuration precision is maintained, but operation time and productivity are reduced
Solution Approach 1:
The patent implements self-service automated slot management where the system automatically performs slot configuration, activation, and deactivation based on predefined policies and current traffic conditions. The automated controller monitors bandwidth usage and autonomously adjusts slot allocations without requiring manual intervention, thereby maintaining configuration precision through systematic rules while dramatically reducing the time required for bandwidth adjustments.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors traffic demand and bandwidth utilization, then uses this feedback to automatically adjust slot configurations. The feedback loop ensures that configuration decisions are made based on actual network conditions, maintaining precision while enabling rapid automated responses to changing requirements without manual intervention delays.

AI summary
The present disclosure provides a bandwidth adjustment method and a bandwidth adjustment device. An SPN device according to the present embodiments reports SPN group information and port flow information for determining whether a bandwidth adjustment is to be performed. An SDN device determines whether SPN devices in a same SPN channel need a bandwidth adjustment in accordance with the SPN group information and the port flow information reported by the SPN device, and after determining that the bandwidth adjustment is needed, transmits bandwidth adjustment information to the SPN devices in the same SPN channel. After receiving bandwidth adjustment information from the SDN device, the SPD device adjusts the bandwidth of link between the SPN devices connected to each other in the SPN channel in accordance with the bandwidth adjustment information.
