Authentication Node Redirection for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, unresponsive authentication nodes can lead to significant network traffic congestion and potential network downtime due to repeated authorization requests, as users attempt to access the network when the authorization system is not responding.
Innovation Solution
The system redirects network authorization traffic to a different authentication node when the primary node experiences degraded performance or becomes unresponsive, and stops redirecting once the node is operational again, thereby preventing network overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users repeatedly send authorization requests when the authentication node is unresponsive, then the chance of successful authentication may improve, but network traffic congestion increases and may bring down the entire network
Solution Approach 1:
The patent introduces an intermediary mechanism (authentication failure detection and redirection system) that detects when the authentication node is unresponsive and redirects authentication requests to alternative nodes. This mediator prevents direct repeated requests from overwhelming the network by intercepting and rerouting failed authentication attempts, thus resolving the contradiction between maintaining authentication reliability and preventing network congestion
Solution Approach 2:
The system performs preliminary detection of authentication node responsiveness before allowing repeated authentication requests. By proactively identifying unresponsive nodes and implementing redirection before network congestion occurs, the system prevents the harmful accumulation of retry traffic while still allowing legitimate authentication attempts to proceed through alternative paths
2Reliability
If the authentication algorithm is made difficult and time-consuming to ensure security, then network security is improved, but authentication response time increases
Solution Approach 1:
The patent segments the authentication process into multiple independent authentication nodes distributed across the network. Each node can handle authentication requests independently using the same secure algorithms, allowing the system to maintain high security standards while providing multiple parallel paths for authentication, thereby reducing overall response time through load distribution
Solution Approach 2:
The system dynamically selects which authentication node to use based on current node responsiveness and load conditions. When the primary authentication node is unresponsive or slow, the system dynamically redirects requests to alternative nodes, maintaining both security (by using the same cryptographic algorithms) and performance (by adapting to real-time network conditions)

AI summary
In response to determining that the authentication function operating on the authentication node on a network is not responsive, a re-direct message may be communicated to at least one edge device on the network that requests of the authentication function on the authentication node be re-directed to a different authentication node.
