Tandem Switch Traffic Routing Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The telecommunications network faces inefficiencies due to the inability to accurately quantify and manage traffic loads at tandem switches, leading to misuse of resources and increased costs for carriers, as tandem switches are often added without traffic analysis, resulting in overburdened switches and underutilized resources.
Innovation Solution
A system and method for automating and managing trunk routing among switches, allowing a third-party tandem manager to direct subscriber-associated call traffic through subscriber-owned or third-party switches, reducing costs by avoiding higher fees associated with LEC-owned switches, and utilizing software for traffic analysis and data tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If tandem switches are added without traffic analysis, then network capacity increases, but resource utilization deteriorates and costs increase
Solution Approach 1:
The system performs preliminary traffic analysis and switch performance evaluation before routing decisions are made. The tandem manager proactively collects and analyzes traffic load data, switch utilization metrics, and cost information in advance, enabling informed routing decisions that optimize resource utilization while maintaining network capacity.
Solution Approach 2:
The system implements continuous feedback loops where traffic load information, switch performance data, and cost metrics are constantly monitored and fed back to the routing algorithm. This feedback mechanism enables dynamic adjustment of call routing decisions to optimize resource utilization across the network while maintaining adequate capacity.
2Reliability
If traffic is routed through LEC-owned tandem switches, then network reliability is maintained, but carrier costs increase
Solution Approach 1:
The system dynamically selects routing paths based on real-time switch performance data, traffic conditions, and cost information. Rather than statically routing through LEC-owned switches, the tandem manager continuously adjusts routing decisions to balance reliability requirements with cost optimization, selecting the most efficient available paths.
Solution Approach 2:
The system changes routing parameters dynamically based on multiple factors including switch utilization metrics, traffic load conditions, and cost data. By varying routing decisions according to these parameters, the system achieves cost optimization while maintaining network reliability through diverse and adaptive path selection.
3Ease of manufacture
If manual trunk routing management is used, then implementation simplicity is maintained, but traffic optimization capability deteriorates
Solution Approach 1:
The tandem manager system performs automated traffic analysis, switch performance evaluation, and routing optimization without requiring manual intervention. The system self-manages the collection of traffic data, analysis of switch metrics, and generation of optimized routing decisions, eliminating the need for complex manual management while achieving superior traffic optimization.
Solution Approach 2:
The system replaces manual trunk routing management with automated electronic analysis and decision-making algorithms. By substituting human manual processes with computerized traffic analysis and intelligent routing algorithms, the system achieves both operational simplicity and enhanced optimization capability.
Data Source
AI summary
A system and associated methods for automation and management of trunk routing among switches in a telecommunications network between carriers connected to a third party tandem services provider or manager (a “neutral tandem network.”) The system and methodology can be used to, among other things, effectuate a business model for providing preferred rates, or other preferences, to a defined group of members or subscribers by managing and directing subscriber-associated call traffic from subscriber-owned switches to one or more tandem switches owned by a third-party tandem managing entity other than a LEC or ILEC.
