Network Node Data Access via Observation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network observation systems consume significant resources and bandwidth, especially in networks with nodes constrained by energy and bandwidth, as they require intense asynchronous interrogations to monitor node states effectively.
Innovation Solution
A method where nodes signal operations to an observation device via a separate communication link, allowing the device to record and transmit information efficiently, reducing the need for direct node interrogation and conserving resources by using a relay device to minimize disturbance and save node resources.

Engineering Contradiction Analysis
1Loss of information
If a central server explicitly queries network nodes using protocols like SNMP to obtain operating parameters and performance metrics, then information on node status is obtained, but significant bandwidth and energy resources are consumed at the node level
Solution Approach 1:
The patent introduces an intermediary component (observation device or proxy) that collects information from network nodes asynchronously and stores it locally. This intermediary then provides information to external entities without requiring direct queries from them. The intermediary buffers and manages the information flow, eliminating the need for frequent synchronous queries that consume node resources, while still providing comprehensive monitoring capabilities.
Solution Approach 2:
The system performs preliminary action by having the observation device proactively collect and store operational information from nodes in advance, before any external query occurs. Information is gathered asynchronously at the node's convenience and cached at the observation device, so when external entities need information, it is already available without requiring the node to expend energy responding to queries in real-time.
2Use of energy by moving object
If asynchronous queries are used to monitor node states, then node resources are consumed less intensively, but the intensity of querying must be increased to observe all successive states
Solution Approach 1:
The observation device acts as an intermediary that continuously and asynchronously collects information from nodes without requiring high-intensity querying. It maintains a local record of node states and provides this information on demand to external entities. This approach achieves both low energy consumption at nodes and high monitoring efficiency, as the intermediary handles the burden of comprehensive observation while nodes simply provide information at their own pace.
Solution Approach 2:
The system creates a copy of the node's operational information and stores it at the observation device. Instead of repeatedly querying the original node for the same information, the system uses the copied data stored at the intermediary. This copying mechanism allows external entities to access monitoring data without increasing the intensity of queries to the actual nodes, maintaining both energy efficiency and monitoring completeness.
3Loss of information
If detailed observation of node operations is required, then complete information is obtained, but significant resources are consumed at the observed nodes
Solution Approach 1:
The observation device serves as an intermediary that collects detailed operational information from nodes and stores it locally. When detailed observation is required, the intermediary provides this pre-collected information without requiring the nodes to expend resources generating responses in real-time. The intermediary bears the resource burden of maintaining detailed information records, while nodes simply provide data asynchronously when convenient.
Solution Approach 2:
The system creates comprehensive copies of node operational data and stores them at the observation device. These copies contain detailed information about all node operations, available for retrieval without requiring the original nodes to regenerate the data. This copying approach enables detailed observation while consuming minimal resources at the node level, as the information burden is shifted to the intermediary's storage and processing capabilities.

AI summary
The invention relates to a method for accessing data related to at least one operation implemented by at least one node device (N1) of a network (R) from a plurality of node devices (N1, N2, N3) of said network, which are capable of communicating via a first communication link (L1). According to the invention, the access method is suitable for receiving a message through which a node device signals, to an observation device, an operation implemented by said node device; for recording at least one piece of information on said operation; and, upon receiving a request from a terminal via a second communication link, for transmitting a response developed from at least part of the recorded information. The invention also relates to a data-transmission method. The invention further relates to an observation device (DT) and to a node device (N1) of a network which implement the access method and the transmission method, respectively.
