Data Connection Control via Pre-established Alternative Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data networks with dynamic or mobile nodes, existing methods face challenges in maintaining continuous end-to-end data connections due to fluctuating transmission quality, leading to interruptions, packet loss, and increased network capacity requirements for connection re-establishment, which affects data throughput and overall network performance.
Innovation Solution
The method involves assessing the quality of data connections based on coding adaptations and proactively setting up alternative connections using higher coding methods to predict and prevent interruptions, minimizing packet loss and reducing control signals by initiating a search for a second data connection before the first one is disconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection search messages are flooded through the entire data network to re-establish a broken connection, then the connection can be restored, but the network capacity required for flooding is not available to other network connections and causes high requirements for network capacity
Solution Approach 1:
The patent segments the connection restoration process by establishing multiple alternative data connections (first alternative connection, second alternative connection, etc.) before the primary connection breaks. Each alternative connection is set up through different routing paths, dividing the restoration task into pre-established segments rather than requiring a complete network-wide flood search when failure occurs.
Solution Approach 2:
The patent performs preliminary action by proactively establishing alternative data connections before the primary connection fails. The source node sets up multiple alternative routes in advance, so when the primary connection breaks, restoration can occur immediately by switching to a pre-established alternative connection without requiring time-consuming network-wide searches.
2Reliability
If the source initiates renewed transmission of connection search messages after a connection breaks, then a new connection can be found, but packet delay increases and data packets that were already sent but could not pass the breaking point are lost
Solution Approach 1:
The patent establishes alternative data connections in advance before the primary connection fails. When the primary connection breaks, the source node can immediately switch to a pre-established alternative connection without initiating time-consuming connection search message transmissions, thereby minimizing packet delay and avoiding data loss.
Solution Approach 2:
The patent maintains continuity of useful action by ensuring that alternative data connections are continuously available and ready for immediate use. The source node keeps multiple alternative connections established and active, so data transmission can continue uninterrupted by switching to an alternative connection when the primary connection fails, avoiding delays and packet loss.
3Reliability
If multiple alternative data connections are established in advance, then connection continuity is improved and packet loss is reduced, but the device complexity increases
Solution Approach 1:
The patent segments the alternative connection management by organizing alternative connections in a structured manner (first alternative connection, second alternative connection, etc.). Each alternative connection is managed as a separate entity with its own routing path, making the complexity manageable through systematic segmentation rather than chaotic multi-path management.
Solution Approach 2:
The patent implements dynamic connection management where the source node can adaptively select and switch between alternative connections based on current network conditions and failure scenarios. The system dynamically adjusts which alternative connection is active, providing flexibility and reducing management complexity through automated decision-making rather than static configuration.
Data Source
AI summary
A method and a device for controlling data connections in a data network including a plurality of data network nodes. The quality of a first data connection is evaluated on the basis of the adaptations of at least one coding used for the first data connection, and a second data connection is established according to the evaluation and used as a replacement for the first data connection.
