Label Path Data Transfer Control for Sensor Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer systems face challenges in quickly adapting to the movement of sensors, as they require manual updates to multiple transfer tables across relay devices, leading to delays in data collection and processing.
Innovation Solution
The system partitions the data transfer path into three segments and uses label paths to facilitate efficient data routing, allowing for quick integration of new sensors by specifying a label path for data transfer, thereby bypassing the need for extensive table updates.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional transfer tables are used for data routing, then data transfer control is achieved, but system complexity increases and adaptation to sensor movement becomes slow
Solution Approach 1:
The patent introduces a label path as an intermediary mechanism between the sensor and the final destination server. Instead of directly managing complex transfer tables at multiple relay devices, the label path serves as a mediator that simplifies the routing process. When a sensor moves, only the label path needs to be updated at the current relay device, and this label path information is automatically propagated through the network, eliminating the need for manual reconfiguration at every intermediate relay device.
Solution Approach 2:
The patent segments the data transfer path into distinct segments: the sensor, the current relay device, the label path, and the final destination server. This segmentation allows each component to be independently managed. The label path itself is segmented into multiple hops, where each relay device only needs to manage its portion of the path, reducing the complexity burden on any single device while maintaining overall system adaptability.
2Reliability
If multiple transfer tables are updated when sensor moves, then correct data routing is achieved, but time loss increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing the label path mechanism and its automatic propagation rules before sensor movement occurs. When a sensor moves to a new location, the system already has the capability to quickly update the label path at the new relay device and automatically propagate this information through the network. This pre-prepared mechanism eliminates the need for time-consuming manual reconfiguration at multiple relay devices, reducing setup time while maintaining routing accuracy.
Solution Approach 2:
The patent employs feedback mechanisms where the label path update at one relay device automatically triggers updates at subsequent relay devices in the path. This feedback loop ensures that routing information is propagated throughout the network automatically, maintaining routing accuracy without requiring manual intervention at each step. The system continuously monitors and updates the label path based on sensor location changes, ensuring both reliability and speed.
3Ease of operation
If manual table updates are performed at each relay device, then data transfer control is precise, but operational complexity increases
Solution Approach 1:
The patent implements self-service by enabling the network system to automatically manage label path updates without requiring manual intervention at each relay device. When a sensor moves, the operator only needs to update the label path at the current relay device, and the system automatically propagates this change through the network. This self-service mechanism eliminates the need for operators to manually configure each relay device, significantly improving ease of operation while reducing the complexity burden on individual devices.
Data Source
AI summary
A transfer path between a sensor and a data processing server is partitioned into at least a first transfer path between the sensor and a first relay device, a second transfer path from the first relay device to a second relay device that transfers the data transmitted from the first sensor, and a third transfer path between the second relay device and the data processing server. A data transfer between each of the sensors and the data processing server is implemented by respectively controlling a pair of the first transfer path and the second transfer path, and a pair of the second transfer path and the third transfer path.
