Hierarchical Network Capability Propagation for Intent Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intent-driven management systems, high dynamicity of services and network capabilities leads to increased interactions between layers due to unfulfilled intents, escalations, and lack of service adaptation, resulting in complexity and inefficiency.
Innovation Solution
A method and apparatus for determining and propagating network capabilities from the bottom layer to upper layers, using machine learning models to translate successfully fulfilled intents into network capabilities, allowing for reduced interactions and improved service adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intent-driven management is implemented with hierarchical layers, then service autonomy and dynamic goal fulfillment are improved, but the number of interactions between layers increases due to unfulfilled intents and escalations
Solution Approach 1:
The patent applies preliminary action by determining and propagating network capabilities from the bottom layer to upper layers before intents are executed. This allows upper layers to have advance knowledge of available capabilities, enabling them to formulate more appropriate intents that are more likely to be fulfilled, thereby reducing escalations and interactions.
Solution Approach 2:
The patent implements feedback by establishing a bottom-up propagation mechanism where network capabilities determined at the bottom layer are communicated to upper layers. This feedback loop enables upper layers to adapt their intent formulations based on actual network capabilities, reducing the need for repeated interactions and escalations.
2Device complexity
If traditional hierarchical intent handling is used, then management structure is simplified, but service adaptation to network dynamics becomes inefficient
Solution Approach 1:
The patent determines network capabilities in advance at the bottom layer and propagates this information upward before service execution. This preliminary action enables services at upper layers to adapt to actual network dynamics without requiring complex real-time negotiations, maintaining simple hierarchical structure while improving adaptation efficiency.
3Adaptability or versatility
If network capabilities are not pre-determined, then system flexibility is maintained, but the number of interactions increases due to lack of service adaptation
Solution Approach 1:
The patent determines network capabilities in advance at the bottom layer and propagates this information to upper layers. This preliminary determination of capabilities allows services to be formulated with better adaptability to actual network conditions, reducing the need for repeated interactions and improving overall intent fulfillment efficiency while maintaining system flexibility.

AI summary
A method performed by a network node for communicating information among a hierarchy of management systems structured as a plurality of layers including upper layers and a bottom layer for managing a communication network is provided. The method includes monitoring an update at the bottom layer after an action is executed in response to an intent specification received from an upper layer. The update includes information relating to whether the action was successfully fulfilled in the communication network. The method further includes determining a network capability of the bottom layer that corresponds to the executed action; updating an identification of network capability with the determined network capability of the bottom layer to obtain an updated identification of network capability; and propagating the updated identification of network capability to an upper layer above the bottom layer according to a defined policy.
