Locality-Based Routing Table Generation for P2P Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional routing systems in peer-to-peer networks are inefficient due to unnecessary data routing through geographically distant nodes, leading to increased costs and inefficiencies as nodes become increasingly dispersed.
Innovation Solution
A routing table is generated based on locality, with nodes closest in proximity preferred, using roundtrip time and IP address prefix matching to determine the best transport options, and a threshold to differentiate significant differences in roundtrip times, ensuring data is routed through the most local and trusted nodes.

Engineering Contradiction Analysis
1Productivity
If traditional routing systems are used in peer-to-peer networks, then routing simplicity is maintained, but routing efficiency deteriorates due to unnecessary data routing through geographically distant nodes
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing locality information (IP address prefixes, roundtrip times) for all nodes before actual data routing occurs. Routing tables are pre-generated with locality scores, so when data needs to be routed, the system can quickly select the nearest node without performing complex real-time calculations, thus improving routing efficiency while managing complexity through advance preparation
Solution Approach 2:
The patent replaces traditional mechanical/geographic routing decisions with computational methods. Instead of physically routing data through geographically nearest nodes (which would require complex real-time location tracking and calculation), the system uses IP address prefix matching algorithms and roundtrip time measurements to computationally determine and simulate geographic proximity, substituting physical routing complexity with efficient computational logic
2Adaptability or versatility
If nodes are increasingly geographically disperse in peer-to-peer networks, then network coverage and flexibility are improved, but routing cost and inefficiency increase due to longer data transport distances
Solution Approach 1:
The system applies local quality by making routing decisions based on local characteristics of each node pair. Instead of using a uniform routing approach for all nodes, the system calculates specific locality metrics (IP prefix matching depth, roundtrip time) for each potential routing path and selects routes based on these localized measurements. This allows the network to adapt to geographic dispersion while minimizing transport costs by always choosing the locally optimal path
Solution Approach 2:
The patent changes routing parameters from traditional hop-count or fixed-path metrics to dynamic locality-based parameters including IP address prefix match depth and measured roundtrip time. By changing the parameters used to evaluate routing paths, the system can accommodate geographically dispersed nodes while optimizing for actual transport efficiency, reducing energy loss despite increased network flexibility
3Measurement precision
If routing tables include only roundtrip time considerations, then simplicity is maintained, but precision in determining local nodes deteriorates when roundtrip times are similar
Solution Approach 1:
The system merges multiple measurement methods into a unified routing decision framework. It combines IP address prefix matching (which provides structural locality information based on network topology) with roundtrip time measurements (which provide actual performance data). By merging these two approaches, the system achieves higher precision in node locality determination - using IP prefix matching to quickly eliminate distant nodes and roundtrip time to break ties among nearby nodes - while managing complexity through a hierarchical decision process

AI summary
Systems and methods storage of adding a node entry to a routing table of an inquiring node of a data network are disclosed herein. An inquire message is transmitted to a publishing node. The publishing node can be configured to publish a routing entry which can be added by nodes of a network. An acknowledgment response can be received from the publishing node. The roundtrip time elapsed between transmitting the inquire message and receiving the response can be measured by the inquiring node. For all node registration entries in the routing table of the inquiring node a determination of whether the inquiring node is closest in locality to the publishing node than to a node corresponding to each node registration entry can be performed. Such determination can be made based on (a) the roundtrip time between nodes (b) node IP address prefix matching.
