Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony systems over packet networks face challenges in managing network resources effectively due to lack of connection path state awareness, leading to congestion, voice quality issues, and difficulty in isolating communication problems, especially in converged networks carrying real-time and non-real-time traffic.
Innovation Solution
A system and method using a connection admission control engine to gather network performance information, balance data flow, and take corrective actions by evaluating performance against thresholds, enabling intelligent management of network resources and call handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection admission control is implemented to manage network resources, then network performance and voice quality are improved, but device complexity increases
Solution Approach 1:
The patent introduces a Connection Admission Control (CAC) engine as an intermediary component that sits between network traffic and resource allocation. This CAC engine gathers network performance information, evaluates it against thresholds, and makes admission decisions. By placing this intelligent mediator in the network path, the system achieves improved network performance and resource management without requiring complex modifications to existing telephony equipment, as the CAC engine handles the complexity centrally.
2Difficulty of detecting and measuring
If real-time monitoring of network performance is implemented, then communication problems can be isolated faster, but use of energy increases
Solution Approach 1:
The patent implements a self-service monitoring system where the CAC engine automatically gathers network performance information from the network itself without requiring external monitoring equipment. The system evaluates performance metrics against predefined thresholds and automatically takes corrective actions when problems are detected. This self-service approach enables fast problem isolation while minimizing energy consumption by avoiding continuous active monitoring and relying instead on event-driven evaluation.
3Productivity
If data flow balancing is implemented across access points, then network congestion is reduced, but device complexity increases
Solution Approach 1:
The patent implements dynamic data flow balancing where the CAC engine continuously monitors network performance information and adjusts traffic distribution across access points in real-time based on current network conditions. The system evaluates performance metrics and dynamically redistributes data flows to prevent congestion, rather than using static load balancing rules. This dynamic approach improves network efficiency while keeping device complexity manageable by automating the balancing process through the CAC engine's threshold-based evaluation and corrective actions.
