Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in efficiently assigning radio access network (RAN) nodes to security gateways, leading to resource utilization imbalances and potential overloading, particularly in handling encrypted traffic.
Innovation Solution
A method involving measuring performance indicators and utilization metrics of RAN nodes and security gateways, performing regression analysis to build models, and creating optimization models that account for resource constraints to determine optimal assignments or reassignments of RAN nodes to security gateways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RAN nodes are assigned to security gateways based on existing methods, then security traffic handling is provided, but resource utilization becomes unbalanced and overloading occurs
Solution Approach 1:
The patent implements dynamic assignment of RAN nodes to security gateways based on real-time performance indicators and utilization metrics. The system continuously monitors CPU utilization, memory usage, and network throughput, and reassigns RAN nodes from overloaded gateways to underutilized ones, transforming the static assignment into a dynamic, adaptive process that resolves resource imbalance while maintaining security reliability
Solution Approach 2:
The system employs feedback mechanisms by measuring performance indicators of RAN nodes and utilization metrics of security gateways, then using this feedback information to optimize assignments. The continuous monitoring and reassignment based on measured metrics creates a closed-loop control system that prevents overloading and maintains balanced resource utilization, thereby improving both reliability and productivity
2Productivity
If more RAN nodes are assigned to a security gateway to handle increased traffic, then traffic handling capacity increases, but the security gateway may become overloaded
Solution Approach 1:
The system dynamically adjusts the number of RAN nodes assigned to each security gateway based on real-time utilization metrics. When a gateway approaches overload thresholds, the system automatically reassigns RAN nodes to other gateways with available capacity, enabling the network to handle increased traffic while preventing any single gateway from becoming overloaded
Solution Approach 2:
The system changes the assignment parameters (which RAN nodes are assigned to which security gateways) based on measured performance indicators and utilization metrics. By adjusting these parameters dynamically in response to changing traffic conditions, the system optimizes traffic handling capacity while maintaining gateway reliability through balanced load distribution
