Network Service Search via Routing Path Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for searching services and resources in networks are inefficient, especially in dynamic environments, as they require continuous updating of directory services and do not scale well in large networks, leading to excessive traffic and resource consumption.
Innovation Solution
A method that specifies a direction within the network by defining a routing path between a source node and a destination node, only including pre-configurable nodes along this path in the search, thereby reducing data generation and scaling efficiently, even in large networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a directory service is used to register and query services, then service location is achieved, but continuous updating is extremely cost-intensive and does not scale well in dynamic environments
Solution Approach 1:
The patent extracts the service registration function from the central directory service and relocates it to individual nodes. Each node that provides a service registers it locally at its own location rather than updating a central directory, eliminating the need for continuous updates to a central service while maintaining service location information availability.
2Ease of operation
If a lookup request is broadcasted into the network (flooding method), then service discovery is achieved, but it does not scale and causes enormous superfluous traffic in large networks
Solution Approach 1:
The patent applies local quality by making each node responsible for maintaining and advertising services locally at its position in the network. Instead of broadcasting to all nodes, services are advertised only to neighboring nodes, creating a distributed local knowledge base that scales efficiently without requiring network-wide flooding.
3Extent of automation
If a directory service is used, then centralized service management is achieved, but it does not take into account topological aspects and location of resources
Solution Approach 1:
The patent segments the centralized directory service into distributed local registries at individual nodes. Each node maintains its own service registration information and topology knowledge, enabling the system to adapt to topological changes and provide location-aware service discovery without requiring a monolithic centralized manager.

AI summary
Method for searching services, resources and/or functionalities in a network wherein the network comprises a multitude of nodes to which routable network addresses are assigned, and wherein the services, resources and/or functionalities which are to be searched, are specified by a source node (Q) that is characterized in that a corresponding direction is specified within the network by at least one destination node (Z) and/or nodes near to the destination node (Z), by which a routing path is defined between the source node (Q) and the corresponding destination node (Z), and characterized in that only pre-configurable nodes near to the routing path between source node (Q) and destination node (Z) are included in the search.
