Node Capability Exchange for Communication Path Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in effectively coordinating and controlling processing functions among nodes along a communication path, especially during dynamic changes or when multiple nodes provide the same functions, leading to potential degradation of information transfer.
Innovation Solution
A technique where each node along a communication path exchanges information about its local and remote capabilities, allowing each node to determine the cumulative functions available and apply appropriate functions based on predefined criteria, ensuring efficient coordination and provisioning of processing functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple nodes provide the same processing functions, then function availability increases, but coordination complexity increases
Solution Approach 1:
Nodes exchange capability information proactively before processing decisions are needed. Each node advertises its local and remote capabilities to neighboring nodes, so that when a processing decision is required, the necessary information is already available without requiring complex real-time coordination queries.
Solution Approach 2:
The system implements a feedback mechanism where nodes receive capability information from upstream and downstream nodes, process this information to determine appropriate functions to apply, and then execute those functions. This closed-loop approach ensures coordinated decision-making across multiple nodes.
2Adaptability or versatility
If dynamic rerouting is implemented, then network adaptability improves, but control coordination difficulty increases
Solution Approach 1:
Capability information is exchanged and accumulated in advance along the communication path. When rerouting is needed, nodes already possess the capability lists from upstream and downstream nodes, allowing rapid reconfiguration without complex real-time coordination or re-exchange of capability information.
Solution Approach 2:
The system is designed to handle dynamic network conditions through periodic or event-triggered updates of capability information. Nodes can add, remove, or modify their advertised capabilities as network conditions change, and this information is automatically propagated through the network, enabling dynamic adaptation without manual reconfiguration.
3Manufacturing precision
If comprehensive capability exchange is implemented, then function coordination accuracy improves, but information exchange overhead increases
Solution Approach 1:
Nodes exchange capability information selectively with their immediate upstream and downstream neighbors rather than with all nodes in the network. Each node processes only the capability information relevant to its position in the path, accumulating local capability lists that are sufficient for making processing decisions without requiring global network knowledge.

AI summary
The present invention provides a technique for determining which nodes are to provide various functions on traffic along a particular communication path. Generally, a communication path may include multiple nodes between which and through which traffic is routed. These nodes may include the communication terminals at either end of the communication path, as well as various types of routing nodes along the communication path. Each node will send to other nodes in the communication path information identifying the local functions it is capable of providing to the traffic carried in the communication path, and if available, remote functions capable of being provided to the traffic by other nodes in the communication path. Each node will receive from other nodes in the communication path information bearing on the remote functions. Each node will access criteria to determine whether any local functions should be applied to the traffic.
