Telephony Traffic Control Module for Congestion Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network congestion in telephony systems leads to queueing delay, packet loss, and blocking of new connections, resulting in reduced network throughput, necessitating effective solutions to manage and mitigate these issues.
Innovation Solution
A system and method that utilize a traffic control module to analyze telephony connection requests, determine traffic information, and decide whether to forward or deny requests based on factors like auto-dialing behavior, policy violations, and potential network congestion, employing techniques such as spoofed replies and alternative routing to manage network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If telephony connection requests are forwarded to intended recipients, then network throughput increases, but network congestion worsens leading to queueing delay and packet loss
Solution Approach 1:
The patent applies preliminary action by analyzing traffic information and determining congestion conditions before forwarding connection requests. The system proactively identifies auto-dialing behavior and potential congestion sources, and takes preventive measures by denying requests or providing spoofed replies before actual congestion occurs, thereby maintaining quality of service while preserving network throughput for legitimate traffic.
2Reliability
If traffic analysis and filtering is implemented to reduce congestion, then quality of service improves, but device complexity increases
Solution Approach 1:
The patent extracts and isolates the traffic analysis and congestion management functions into a separate traffic control module. This module specifically handles connection request analysis, traffic information determination, and congestion response generation. By extracting these complex functions from the core telephony system, the patent improves quality of service while containing device complexity within a dedicated component rather than distributing it throughout the entire system.
3Loss of energy
If spoofed replies are sent instead of actual system responses, then network load is reduced, but information accuracy deteriorates
Solution Approach 1:
The patent introduces spoofed replies as an intermediary mechanism between the traffic control module and originators. Instead of directly denying connection requests or forwarding them to recipients, the system sends spoofed replies that mimic actual system responses. This intermediary approach reduces network load by preventing unnecessary traffic generation while maintaining a level of information accuracy that preserves protocol compatibility and prevents originators from detecting the congestion management actions.
Data Source
AI summary
A system, method and non-transitory computer readable storage medium comprising instructions that when read by a processor perform receiving a telephony connection request, determining addressing information regarding the telephony connection request, the addressing information including at least routing information or a phone number, determining traffic information regarding the telephony connection request based on the addressing information, the traffic information including previous telephony connection requests, sending a reply in response to the telephony connection request, wherein: forwarding the telephony connection request to an intended recipient would result in a system response, and the reply differs from the system response.
